How about the world championships?
From the 3x world champion and multiple TdF and Giro stage winner:
"There is no need to spend more than 25 minutes warming up. In fact, I’m quite certain I have left many of my best performances on the ergometer before some time trials even started by warming up too hard and much too long."
The second part of that is interesting. Makes physiological sense, right?
