Lol! I’m genuinely interested by that answer Weeksy Care to elaborate ‘over there’ ??
In simple terms, the fast guys (not just in MTBing, but other similar sports) are not just fast because they have skills, or balls, but they have the ability to do it harder and faster than anyone else. It’s proven watching other things like motorbike racing that the fast fellas are fast because they are likely to be more used to the speed, more used to the HR, more used to the training.
Take our resident fast XCer here, Njee, he’s putting in 190bpm averages for an hour and a half, not only can he keep up that HR, but he can obviously maintain concentration too, he’s got the strength, stamina and fitness (although he’ll argue now) that other riders lower down don’t have.
However, I’d bet you on a non-pedally DH ride, he’d be closer to my level than he would be on an XC ride… because your average blokes will only go so fast on a downhill I rekon. He wins and crushes me because he’s fitter, stronger and faster.
There’s obviously a finite level where this turns round and person A needs to up his skills (or bike) but not many here are at the level where a free ‘upgrade’ of riding an extra 10 hours a week wouldn’t give them a performance result.
