Thinking about this some more since I posted earlier. I dont think I ever could walk away from cycling. It may be that in the future I switch my intrest from Tour's to local or domestic racing, or the u23 or something, but Ive been following the sport and to a lesser extent participating in the sport for 25 years.
One thing that has changed for me, is that I dont always support winners anymore. I celebrate podiums, or top 10's or top 20's from riders Im pretty sure are clean. I support great performances from riders even if they dont win, or even finish a race. I couldnt care that Contador won the tour, or Schleck came second, but I do enjoy the fact that Hesjedal placed well, or that geraint came second on a stage. I would rather support a clean rider finishing 10th now, than a doped one winning.
There are obvious exceptions, I cant help loving vino.
The positive side of me says what I said earlier. Ten years ago every positive was a step in the wrong direction, now, hopefully every positive is a step in the right direction.
The cynic in me says, if it appears too good to be true, it probably is.
