Is his watts so much lower due to tailwind or fitness?
I can only speculate, but being fitter doesn't mean you ride at lower watts, it means you can ride at higher watts. His (or mine) power meter might be out, there might have been tailwind for him, I had slight headwind, and I am guessing he was on a TT bike, as this road is a tester paradise. He might also have been in a bunch.
Edit: His wattage is really low for that speed though, so either TT bike or a bunch. Or the mother of all tailwinds.
