For the last two days I've been over here in Adelaide, at the Superdrome and some motel close by, looking after the Victorian NTID sprint squad as part of the NTID sprint camp that's running here for four days.

I've been lucky enough to work with Sean Eadie (who regular readers will know of) and Bryce Mitchell who's one of the WA NTID coaches, running a couple of training sessions on the track and also generally looking after the squad.  I've got 10 riders in my direct care, and while we have support from Josh (NTID co-ordinator) it's a daunting task.   To put it in context, we'll have to do two days of racing (sprinting, which is very coach-intensive) with my squad having just me to look after them, after two days of training sessions and other 'camp stuff'. The state squad, which isn't that much bigger, has three coaches and two mechanics and a host of family people to help out.  And they reckon they're over-worked!  Heh!

This is not a complaint,  I'm loving the opportunity to learn from these kids and also the other coaches, I roomed with Sean last night and we had some really good talks on sprint training philosophy and so on which I hope will end up with Sean and I co-authoring "the" book on sprint training ("the" book because there isn't one at the moment).  I've got Gary West's (national sprint coach) list of sprint drills to add in to our standardisation project that you can see a glimpse of here.  We have to dispel the old ways (no, sprinters do NOT need to do lots of road miles and race road in winter, that SLOWS THEM DOWN! FFS!).  I'm thrilled to be on the same page as Sean on this and we'll be able to work together to drag a lot of the current coaching practices for sprint out of the dark ages.

I'm incredibly fortunate to have been given this opportunity by Hilton and the guys at the NTID.  Today I got to assist (in a very minor way, I was just a start-line holder for a drill) the AIS team training, getting to work with champions like Anna and Kaarle is just brilliant.

We're going to be seriously under the pump tomorrow, the racing starts and there's a full afternoon-evening's sprinting for all my guys and also research to carry out on how the other guys are racing and so on.  The kids have to manage their food for the afternoon/evening on their own, we're taking them on a 'guided shopping trip' tomorrow to help them choose foods that they can race on during a long block of track time, then lunch, then in to the track at ~1pm.  We don't expect to get out of there 'till 10pm or so, then a very late dinner and back at 8am on Sunday for more. 

It's my job to look after them all, get them in the right state of mind, manage any incidents, provide pre-race tactical support and post-race debriefing.  I'm very excited by the opportunity and the pressure and it's going to be a blast. I have a great team of riders to work with and we're all going to work together.  Don't call me, I'll be busy!  Bring it on.

I see on the Interpipes that Carnegie-Caulfield have cancelled the Modella road race today due to concerns about high winds.  I commend them for this decision.  Organisers have a duty of care.  I wonder what conditions are like out at Eildon today for the Junior Tour?  Weatherzone suggests 72km/h wind gusts.  I hope we have the same level of commitment to rider safety that CCCC have shown.

Today I'm working in at Cycle Science Mitcham (as I do on most Thursdays).  We often get reps in to try to sell us stuff.  Pete, who owns the shop, has a PhD in biochem and is a very smart man and a real scientist.  

So anyway... We don't stock Skins, or any of those other faux-compression clothes, for example.  No evidence, go away ...

Now, today, a rep shows up, from 'Eken Human Performance Enhancement'.  Yes, alarm bells are ringing ...

They sell those hologram/magnetic/snake-oil placebo bracelets that you may have seen around.  Buddy, you're in the wrong place ... GTFO!

My original intention for the aI was to have some racing for the pure sprinters who have nothing 'til summer.  But, I've been underwhelmed by entries and late withdrawals which I'm surprised by, but if that's the market, we have to adapt.  So we're opening it up a bit, not to all comers, but relaxing the entry criteria.  The race is tomorrow night and we'll see who shows up!

Prologue, ho-hum. 

Stage 1.  Bizarre crashes, but normal for the first week.  Everyone's desperate to snag a win early to take the pressure off.

Stage 2.  Guys, it's a rainy road, ride like it's a rainy road.  Old racing adage : You don't win a race on a descent, but you can lose one.   There's always been narrow roads and the risk of rain in the Tour.  At least it wasn't raining on the pave ...

Stage 3.  Pave.  Always going to be decisive.  Way back on '03 or '04 when it was last there, Armstrong and the other GC contenders were freed of Iban Mayo on the Pave.  It's a selective surface.  It's always been said that the first week of the Tour weeds out the specialists, ie: it hurts the pure climbers. The stages are long and hard and they soften up the lightweight mountaingoats.   The first week is why pure climbers very rarely win the Tour. This time it was Frank Schlek, C'est la Vie.  Armstrong lost time too, Contador, Andy Schleck and Evans coped well.  Cancellara had a sook about it (two days in a row, Fabian, channeling Cadel eh?) as did the old cheat (Bjarne Riis, btw, he had his TdF win stripped of him for cheating, but read this  .... Um, Bjarne ... You didn't win the '96 tour, you cheated and that result has been purged) but it's an important part of the Tour.  Take out the hard bits of the first week and you may as well do half a dozen ITT's up mountains to decide the tour.  The Tour is bigger than that.  It's bigger than the riders.  It's a race that requires a lot of all round abilities and a little bit of luck.  The great riders make their own luck.

Stage 4.  What is this, the rebirth of the old sprinters?  Petacchi?!  Two stage wins?  Wow.  Robbie McEwen's still got the smarts but hasn't got the legs anymore, but Cavendish, if I was one of his leadout riders I'd be furious.  You bust your guts to set him up for a stage and he sits up and watches the finish.  Not how to motivate your team mates.  Roll out Zabel and Kursipu!

Armstrong, 7 times winner .. Undisputably the greatest tour rider of all time.  Last year in his comeback despite team issues and injuries, 3rd place.

Last night, he's the fastest of the real contenders in the prologue.  His team mates, right up there too (team time trial form is therefore very good) Early days, yes .. but ominous.  It's going to be another fantastic tour.

Every time you do a drill that involves crossing a finishing line, throw your bike.

Really.

Every. Single. Time.

Make it automatic, a reflex.

Races get won and lost at the throw.  At the end of a race it has to just happen.  Make a habit of it now.

I had to defer the DUCCs session this morning due to rain.  Given that it's freezing cold outside and windy it's a good day for being indoors.  I've just been to the butcher to get the 4.5kg of mince beef for tonight's spag boll for Spin and it's bloody cold out!  So today's jobs - work on sprintTracker to get it to the point where I can (still with a lot of manual hacking) enter some individual efforts into the database.  I'm also going to keep chipping away at the sprint drills page.

I did get a good chance to speak with Martin Barras last week, his sprint progression is this :

1. strength
2. power
3. acceleration
4. speed
5. speed-endurance

He has his sprinters gym work set to lead the program by around two weeks.  For example :

In a strength block, they're concentrating on strength in the gym and on the bike (squats, deadlifts, legpress (if you must ...) in the gym, K1's on the bike).  They max out on strength in the gym about two weeks before they do on the bike, and start working on power (cleans, snatch, hang clean pulls, clean pulls, ballistic leg press etc) before they switch the emphasis over to power on the bike, and so on.  The rough gym to bike matchup is this :

I'm going to see if I can get more information about the gym work that Craig Colduck used during the speed and speed-endurance blocks.  Craig wrote a famous article that I have a copy of here.  I'd also like to compare this to how Gary West is programming these days and also John Beasley.  There's many ways to skin the cat!

Following the "if you want to rise to the top, start in the mail room" philosophy, I've started at the bottom as a sprint coach, as a lowly assistant coach to the NTID here in Victoria.  It's a great opportunity to learn from Hilton and also as many other sprint coaches as I can.  Along the way I'm documenting sprint drills to a level of detail that should make them useful.

You can see a sample here : The motorbike double-jump.

The plan is to document all the sprint drills I come across, get power data from them, draw diagrams, use animations where necessary and useful etc.  This will take place here mainly, but hopefully will end up being used as guidelines (in some form or other) for sprint coaches in all of Australia to use as drills.  ie: we'll have a reasonably consistent naming and implementation system across the country, so a rider training with us in Melbourne can go over to Perth and know what an MACC or a K1 or a windout is and it'll be basically the same drill.

Remembering , of course, that these drills are not what sprint coaching is all about, in the same way that a spanner is not what being a mechanic is all about.  They're tools to do a job, I want to catalog and describe them to a level of detail that as far as I'm aware, hasn't been done yet.

I'm pretty pleased.  Apart from a positive trend in my peak power output (up, not as much as I'd like, but still consistently going up is good, after a bit of a slump for a few months) I got offered a paid position with the NTID on Tuesday night when I was up at the AIS at the NTID coaching conference.  I didn't want to write about it here until I'd had a chance to talk to a few friends about it.  It's a very part-time position working as an assistant to Hilton Clarke with the Victorian NTID sprint squad.  This is basically what I've been doing for the last few months and it's been recognised by the guys at the NTID and they've committed to paying me to continue to do it.

As you can imagine, I'm very happy about this.  Paid coaching positions are few and far between and this is a great opportunity to develop further as a sprint coach and learn so much more, with a little bit of financial help.  I've done a lot of hours (I guess at roughly 250 hours since February, ~20 weeks, ~13 hours a week, give or take) helping that squad so far for 'free' (really, it's like being at school, I don't expect to get paid when I'm learning and aren't really a lot of use) as well as a bit of paid work while Hilton's been having his knee replaced, which will soon be over. Hilts will be back on deck and I'm sure the guys in the squad will be glad to have him back. 

I've done my best but I'm far from perfect when it comes to running some of the drills, in particular some of the motorpacing stuff is quite tricky to get right and I have a lot of practice and instruction to receive before I'm competent.  Getting the pacing right is critical in drills like motorbike entries, each rider needs a different entry speed, different rate of acceleration and so on, and some need me to go very fast indeed (getting close to 80km/h) which I'm still not comfortable doing.  I hit 80km/h on Saturday pacing one of them, and that's scary-fast on the velodrome on a motorbike.  In some ways it'll be frustrating to have to go back to being the assistant at the training sessions when I've been running the show for about a month, but I'll suck it up and it'll be a good, humbling experience when it happens.

Martin Barras (former Australian Sprint coach) is going to be at DISC on Thursday as part of the level 2 coaching course that's running there at the moment and I'm going to sit in on his session (and not ask any questions, ok!  Yes I will behave, Brendan!) and see what interesting things he has to say.  At the level 2 course I did back in November last year in Adelaide, Craig Colduck was one of the presenters.  Craig was Martin's strength coach and we got the chance to see a lot of the nuts and bolts of his programming style, getting a chance to see how Martin did it directly from him will be great.

We had a good turnout at our DISC session tonight too, I'm pleased to see growth in our little sprint group, I'm gradually handing over the reins to Nathan for the enduro programming and session running, having two of us means I can concentrate on my sprinters while Nath looks after the enduros, so far it's working well and I think everyone who attends is benefitting from having the two of us working together.

We're running an invitational sprint round at DISC on the 9th of July too, which I need a few more riders to attend, if you're interested you can read about it (and the invitational criteria!) here.

And ... I'm going to the AIS/NTID sprint camp in Adelaide in mid July to help out, I'll miss one of our DISC sessions, but Nathan's ok to run it on his own and the sprinters will have plenty of stuff to do without me.

Finally, I've got more track powertaps to play with, I think we've got, between myself, Hilton, the VIS and NTID six of them.  I swapped over the axles in two of the VIS ones today to use studs (conventional track nuts) from the rather fiddly bolts they originally came with.  Darryl Perkins is building the most recent pair of hubs into two more wheels which we should have in a week or two.

It's all go ....

I had to leave the NTID conference early on Wednesday, missing a few interesting talks, hopefully there'll be a DVD or at least a booklet summarising the ones I missed, which looked pretty worthwhile.  I came home in a little (80 seater) turboprop plane chock-full of families with babies (why?!)  but survived the ordeal of daddy encouraging little Johnny kicking the chair in front of him without having to channel Hilton on daddy .. Just ..

We had a solid night in at DISC with the NTID squad, it was bloody cold, started at about 12 or so degrees and warmed up(!) to about 14 by the late afternoon.  This meant that times would be a bit slower, but everyone rode well and it was a good session.

Thank you to Stewart Lucy for running the spin session for me on Tuesday, and to Dino for heating the bolla to feed the troops.

I'll get the next track and spin session programs up soon, and am looking forward to a good flaying on Sunday at DISC with the aboc Sprint Squad!

One of the over-riding themes of the NTID conference so far has been the "X-factor", which isn't physiological (unless you consider brain/personality physical, which you may well do, and I may agree with ... but anyway ..).  I've touched on this myself recently.

I'm still not sure ... The x-factor is best defined as dedication and passion, and much seems to be made of the fact that the most dedicated athletes (and ballet dancers, violinists etc ...) are the ones who reach the elite level.  As a result, there's been a bit of a cultural shift in the talent ID process, they're (we're!) trying to focus on x-factor stuff more.  I agree that it's important and much is made of how much and how well someone trains leading to their elite-level performance.  But is the tail wagging the dog?  I suspect to a certain extent it is.  The kids that naturally do very well (the talented ones!) get positive feedback, so they enjoy their pursuit, they then practice more and smarter, and get better.  But they have to have talent first, I think.  The feedback loop seems to be being forgotten or overlooked in the haste to redefine selection criteria.   Not always is it the most talented physically (sometimes for them it's too easy, which leads itself to complacency or fear of failure), but I suspect that the current emphasis on the X factor may be taking things too far, and most coaches gut feeling would probably reflect this. 

Interesting stuff all the same...

While the NTID isn't paying me, I am getting a few perks.  I'm off to Canberra (sitting at Tulla at the moment in the departure lounge) for a two day conference on talent ID at the AIS.  Some interesting speakers, on I'm looking forward to is a bloke from the air force who's going to talk on the things they look for in fighter pilots.  If it's as interesting as the talk at the NTID Cycling conference in Adelaide in May by the police psychologist it'll be excellent.  I have to leave early (on a little Dash-8!) to get back in time to be Hilton-Virtual at the NTID training session at DISC on Wednesday, but will still get the keynote speakers.

This does mean I miss Spin tonight, but that's ok, I did the ergo session yesterday on my recovery day so my sprinters, I have hurt like you will and it is good!

See you when I get back ....

Over the last few months I've collected quite a bit of data from the NTID and aboc sprint squad sessions with track power meters.  We haven't done anything with the data yet, but just collecting and having a quick look at it.

Now the data isn't perfect, but it's reasonably good and I'm going to use it to try and sort out which of the drills we use at track training are the best at producing overload.

Huh?

In the gym, we manipulate three main variables - intensity (how heavy the weight is), volume (how many times we move it and how far) and recovery (how much time you get between reps and sets).

This is because we want to overload at least one of these variables every time, to disturb homeostatis and drive an improvement.

On the bike, we need to do the same thing.  We need to manipulate intensity, volume and recovery - but we don't have the same easy way of manipulating intensity that we do in the gym.  With, for example a squat or a power-clean, we just add more weight to the bar.  Simple .. We can micro-load with humiliator-plates if we need to (0.5kg plates, everyone loves the humiliators - they're tiny, but they make it so much harder!).  Up goes intensity.  The other two variables are trivially easy to manipulate as well.

On the bike, how do we do that?  Up the gears?  Ok, except that we never really get a 'fail' on the bike, the rider can turn any gear we put under them (on a velodrome anyway).  Up the speed, by chasing a motorcycle or another rider etc, and up the cadence by using small gears at high speeds.  These are all ways to do it, but I don't think we've ever really looked closely at how well they work.  The traditional sprint drills we use are all based on experience (which is not to be discounted!).  Now we're collecting a lot of data, we can start to see which drills get the best overload events out of our athletes - which ones produce the highest peak power, for example, or the highest power at a specific cadence range, the highest torque and so on.

Hopefully with some careful analysis of the data I've collected, with a bit of help from Dr Dan at the VIS, we'll be able to identify which of the drills we use are the best at overloading our athletes so we can train them smarter.  Watch this space!

Many of you by now know that I'm working for the National Talent ID in an ad-hoc sort of way, indirectly anyway, as Hilton Clarke's assistant.  The sprinters, mainly (I'm still doing a little enduro work, but nothing sophisticated).  I've now spent a considerable amount of time with the sprint squad here in Victoria, and without exception they're a very talented group.  Working with them is a pleasure.

But that's not what I want to write about.  I want to write about how we tell who's got "it".  Ie: who's got the drive to get to the very top.  It's a relevant topic to me now, and one worth reading widely on.

This came across on a coaching mailing list called "supertraining".  It's by a famous author called Daniel Coyle, who's pretty well known, it's fair to say.  He wrote a superb book on Lance Armstrong called 'Lance Armstrong's War'.   He makes the observation that being the sort of athlete that rises to the top is a mental thing - it's about dedication and commitment (and all those cliche's!).  He's right, but I think in our area, he's not all right - By that I mean he's only got half the picture and that may be because he's listening to coaches who are dealing with pre-sorted athletes.  Mark Rippetoe makes the point rather bluntly (as is his style) when he says that most elite level coaches have little idea of what they're doing with regards to athlete development because they're working with athletes who are pre-selected.  I think Rip's not right there (and he was talking about American football coaches, so I've taken this way out of context!), but I think understand what he's trying to say.  Armstrong himself got it right, I'll roughly paraphrase from memory : 'if you don't have the legs, no amount of mental strength will help'. The truth is you need both.  You need talent and drive.  Drive without physical talent will lead to frustration or delusion, physical talent without drive, to nothing at all.

So, back to talent ID.  How do you tell who's good before you train them for years?  Part of it is physiological screening (a fancy way of saying tests).  This gets the exercise physiologists all excited.  They get wattbikes out, put kids on scales, they do vertical jump tests, they measure thigh diameters, if they're really lucky they get to do muscle biopsies on their victims and soon enough they'll be able to do genetic tests.  Wow ... What does this achieve?  It gets the ones who are good physically, at least (and this may change if and when gene testing gets sorted) at the time of the test.  They do a lot of correlating.  They get very excited and get paid to do it.  It's interesting, but it's not all there is to it.  Far from it.  These tests are, by necessity, crude and can exclude those who do have real potential but haven't blossomed yet. 

Sometimes, it's the kid that fails the tests who ends up at the top.  I can bring something personal to this, when my Dad was a kid he was a bit of a swimmer, and he got tested by some ex-phys who basically told him he was unfit.  A week later he set the 6th fastest 200m butterfly time in the world.  I spoke recently with Ken Tucker at a conference in Adelaide. Ken was Anna Meares' coach when she was a kid, and he said that Anna wasn't great as a kid.  She certainly wasn't talentless, but she wasn't as naturally quick as her sister Kerrie.  Kerrie was outstanding (and went on to win a few medals of her own!).  But, Anna kept on improving and she had the right combination of talent and drive that took her to the very top and has kept her there for a long time.  Ken saw in Anna the qualities of a genuine champion but it took time to come out.  She was fortunate to have a coach that had the vision to see it in her.

So it's the right combination that matters, not (as Doyle implies) mental drive on its own, unless your game is chess!

We need to test for obsessive (healthy!) desire to be the best that the athlete can be, and that's something that I doubt can be easily done, I suspect it's something that some kids grow into given the right environment.  I think I can see the signs in a very select few that I'm lucky enough to work with.  It's rare, and you can see it in their eyes when they do a hard effort, when they don't shirk a hard session, when they do 'the hard yards' that we ask of them as their coaches, not whinging about them but relishing them.  They have to want to hurt and have to be prepared to make some pretty big sacrifices to get to where they want to be. I'm going to quote one of them.

Cycling doesn’t shape my world, it’s everything I am and everything I hope to be.

drive.  Priceless.

My sprinters are getting restless, and I can't say I blame them.  Although there's an NTID sprint camp in July some of them have forgotten about and not everyone gets to go to that, so their motivation (especially the younger ones) drops off when their main races are not until late next summer.

So I'm thinking we might run an invitational sprint round of the SSS over winter, call it the IaWSR! (I'm a wuss racer?) - anyway ... I may be able to grab one of Blackburn's dormant Friday nights.  This won't be like the summer series, although the structure would be the same (F200, grading, round robins and then finals) we'd make it invite-only and really only for pure sprinters (ie: if you're racing road etc, this is not for you, this is for the specialists who are wanting some racing over winter), with a minimum qualifying time, at the moment I'm thinking a 13.5s F200 at DISC, but that number might change.  We want J17's to be able to race it, J17 for next summer, that is.

I'll need buy-in from Blackburn, and from Sue (we need her commissaire skills) and also the NTID (ie: Hilton, I'm not at the reigns full-time, he has to make the call on the NTID's involvement), but at the moment some possible dates are Friday the 9th of July or Friday the 6th of August.

Everything on bicycles is at least 10 years behind motorcycles and cars.  The Kamm Tail was originally developed in the 1930's in Germany.

Now it's showing up on bicycles!

Our distant cousins over in triathalon-land think aerodynamics matters, and they're right, but it REALLY matters at 60+km/h in sprints.  Will this technology make it into sprint bikes? 

Hilton Clarke had his knee replaced on Thursday last week, and while he's away I'm looking after his NTID and VIS sprint squads (and a couple of CCCC ringins), we had our first completely Hilton-Free-Day on Saturday afternoon.  The session was all K1's which is basically a load of gate starts over short distances, the format being 3 sets of 3 reps of starts, each set has reps going up quarter, half and three quarter lap, and each set goes up a gear.

Generally they all did pretty well, I had to get a little bit cranky at the end, as the drill usually finishes with a small gear quarter lap effort, and some of the lads mucked about during it, it was pretty funny, but at the same time, they're there to train and I had to make sure they did their efforts properly.  Guys, if any of you are reading this, you can horse around between efforts, but you do your efforts at 100%, or you're wasting your time and mine.

In other news, Nathan's taking a bigger role in the DISC sessions now, he's looking after the enduro stream including programming for them, and is also doing more of that at Spin.  I'm happy that this is happening, Nathan's almost finished his level 1 and he's ready to take more responsibility for that side of things.

And we had a time trial on Sunday, run by Blackburn and with CSV looking after part of it. I was the announcer, but didn't have much of a job to do except call riders to the start, which was ok for the CSV Open, but the combine part was a mess, no-one's numbers matched what was on the starting list and the on-the-day entries didn't fit anywhere.  We need to stop the on-the-day entries altogether for TT's.

I'm glad I wasn't riding the CSV Open part of it - not because I don't like TT's (which is true!) but because the CSV guys just packed up and left with no results.  WTF?!  The results are up now, which is good, but at the time they just left.   Not good enough.  I don't know if Blackburn ended up getting the results done and having a presentation for the combine event because I had to get going, but they're not currently on the Blackburn website. It's not good enough these days.  It's embarrasing to be a part of when this happens, and more importantly, keeps happening over and over.

But .. We did run a good session at DISC on Sunday afternoon, Nathan had the enduros doing handicap starts and then some brutal efforts while the sprinters did powerjumps and then chased the motorbike around and around.  We all left well fried.  Today I was at Blackburn again coaching the DUCCs but only three showed up, so instead of doing blocking practice, we did flying 200s and match sprints.  The guys enjoyed that and learned a bit so it wasn't a waste of their time.

I did get a small bit of time to speak with Mal Sawford (CCCC president) about some inter-club stuff and in particular volunteer management, but we didn't get a chance to reach any conclusion, he had to race!  At least the ideas are on the table.  I still think that the northern combine model is worth trialing.  Here's more about how they do it. Mal is skeptical about its effectiveness in our combine because he is of the opinion that the NC races require a lot less manpower to run, but I think it's worth a try.  I guess that's up to the race committee people to sort out, but there is goodwill between the clubs and that's the main thing.

I think the Summer Sprint Series is a pretty good thing, but then, I would, it's my baby and all parents are irrational and myopic.

Cycle Sport Victoria have an award for the club promoted event of the year.  The forms and so on are here.

Should we nominate for it?  Has anyone got the time to bash out two pages of guff about it?

I'm a book junkie, really ... Can't get enough. On the bedside table (ok, my floor...) is "Supertraining" by Mel Siff and a pile of other training books and novels etc.  My latest bit of bedtime reading is the second edition of "Training and Racing with a power meter" which arrived in the mail yesterday.  Not that it matters but this was one of the first copies published and it has the author's signatures in it.  Uhuh ... Someone else scribbled in my book!  Anyway ...

I've got two copies of the first edition (don't ask ...) and one of the second.  Hopefully I won't get another copy of it soon.  A very quick summary; this remains THE book on power training for enduros.  It's not quite totally useless for sprinters, there's a chapter that talks about track for about two pages and doesn't (in my quick scan last night) mention sprint, but there's a page or two on BMX, which is very similar to track sprint.  Hopefully I'll get a chance to read it soon and try to glean something useful from it.  Dr Dan from the VIS and I have been looking at data from some of the VIS sprinters and power is a great tool, but 95% of the book is about endurance thresholds etc which we just don't care about!

I also got another power meter today for aboc, another Powertap, it's the Pro +, and will be used by Nathan with his enduro riders.
