aboc's been reasonably unique for some time (started in 2003) in being aimed primarily at recreational racers and beginning event and racing cyclists at a realistic and affordable price.  There's a few more starting to crop up, a newish one is David Heatley's Cycling-Inform.  I'm guessing he's mainly competing with Simon Quick's Quickcycle (price is about the same anyway), and is charging $97p/m at the moment according to his site.  I think this is a good thing, but am a little disapointed at the marketing spin he's chosen to use on his site, and I quote :

Finally a cycling coaching program that is specifically geared
for a busy cyclist that has to fit their training around family 
and work commitments.

I think that's a little misleading.  aboc has been specifically working with balancing life and cycling for 'the rest of us' for five years or more and making a point of it.  No problems with the competition at all, the more the better, and it's good to see everyone else running camps in the mountains too (what took you so long?!).  I'm all for it, I'm confident that aboc is great value and despite some encouragement to raise our charges, aboc will remain very affordable and will not be focussed on elite riders at the expense of the rest of us.
