I'm new to this siteand forum, but have been watching cycling for 20 odd years. Im not a cyclist, but I know a bit about performance athletes.
I really enjoyed yesterday's stage. For me, the indications were there that I was watching a sport on a more level playing field than before. Contrary to it being dull, I thought it was riveting as all the lead riders appeared to be hanging in at the edge of their capabilities....which is what you would hope and expect to see in a cleaner race. Voeckler was hanging in there, but seemed to grow in confidence when he witnessed the difficulties that the others were having at close quarters.
Voeckler made a scarcely veiled reference to being blown away by Armstrong and Basso in 2004 and concluding that, even in his current good form, he could not have stayed with them. He implied that this was down to cleaner racing.
I was fascinated to read the analysis of the Luz Ardiden on "The Science of Sport" blog. The conclusion was:
"
All of this further confirms, to me anyway, that there is a "limit" to how much power a rider can produce going up a hill. I've given the theoretical argument why this is the case before, and I estimate that around 6 to 6.2W/kg on these long climbs is the ceiling for normal performance. But now, as we get more and more data, we're seeing the same thing emerge over and over - guys just do not ride these HC climbs to finish stages at 6.3, 6.4 W/kg or higher."
Not without improper assistance anyway. The Armstrong/Basso ascent was at approx 6.4w/kg output if I remember rightly.
I may be wrong...TV may be unclean, but I doubt it. I think it more likely to be a combination of factors:
1. the home MJ effect
2. good form coming into the tour
3. increased confidence in his own climbing ability....seeing cleaner competition
4. the "stars" operating within a more natural performance envelope.
I haven't seen any power output figures for yesterday, but I suspect they, in conjunction with times, will bear this out.
Performance at around 6.4w/kg is what you'd expect with the assistance of blood doping. Performance at around 6w/kg is what you'd expect to see clean.
