I'm sure you're right.. but even at my crap level, I've had jokey conversations with some much better runners where we were talking about getting competitive advantage from being at altitude in the Alps, oxygen tents etc. Of course that's totally legit, but the hyper-competitive mindset is still there, even at that level of athlete. Funny & pathetic, but it's not about money very often I think. There have been some highly embarrassing cases of totally rubbish amateur athletes being busted (cylists) for self administered EPO regimes! Incredible but there's no end to human weirdness.
Anyway, I need some un-shattered illusions or I'll go and get the rope
