Take a peek at stage 3 of the Vuelta a San Juan last week, the 15km/9.4mi time trial on road bikes (TT bikes and aero bars prohibited to level the field for less well funded and equipped teams. It's interesting to see the ergonomics and styles used to tackle a relatively short time trial that's just long enough to separate the sprinters, pure climbers and pure long range TT specialists.
It was won by Remco Evenepoel, who weighs maybe 61 kg, by more than 30 seconds over the 2nd place finisher. Check out his form. I'm not sure I could do that for a mile, let alone 10. But he looks relaxed, well within his comfort zone while still trouncing the competition.
I'd like to see a road bike only TT stage on every grand tour. It'd be more relatable to many viewers. Most of us can find a 5-10 mile route suitable for time trials in our areas. I've chosen a couple within easy riding distance of my home.
