I hear youazdroptop said:I don't like it much either, but we've supposedly tried to clean up sports here in the U.S. and we all know they're not clean. Normal humans don't run a 4.3 40 at 260 pounds. Just like normal humans can't race for 3 weeks straight across huge mountain passes and perform like our cycling heros do. I climb my local 26 mile high mountain and I'm toast for 3 or 4 days! granted I'm a 40 year old lowly cat 4 racer who only trains 12 to 16 hours a week.
However, I do think that TDF is possible without the use of PEDs. If it was possible for guys to do it in the 1910s without PEDs (granted they were trying to cheat but they were doing themselves more harm than good with the stuff they were taking) it is definetely possible today. However it will make for a dramatic change in the way the Tour (and grand Tours in general) is raced and the times and speeds recorded.
