Can one get real stats for TDF racers?
Compare GC leaders/winners, Hill Sprint winners, Flat sprint winners, Hill Climb leaders (poka dot), etc.
Rider weight, bike weight, etc.
How many riders are logging power stats?
It is likely easier to get real data from a race than getting it from a lab. Is 100% effort in a lab the same as 100% effort during a race?
What about international track finals? TT cyclists?
