Somewhere – I suspect Twitter – I discovered that a certain energy-drink maker is webcasting all of this year’s World Cup mountain bike races, both live and on-demand. I’ve devoured all of the cross-country races, which have so far taken place in Europe but which will shift to Mont Ste. Anne, Quebec, this weekend. The racing is spectacularly engrossing, the athletes are stupendously strong, and my binge-watching has stoked my lust for a mountain bike like this one.
