Wrong.

The measurement of power mentioned here is a good indication of ability. Cyclists use the proportion of watts produced per kilogram of body weight to provide a truly objective measure of performance. This number takes into account the mass of bones, muscle, connective tissue, and other physical attributes that create power. If Jillian's power output over the same amount of time is comparable to other athletes of her gender, age and ability, then it is a fair competition. The numbers don't lie.
