e-mtb is going to be who can pedal thier bike above the limit best, surely?
I’ve been to Les Gets. I’ve got a good idea on what the course is going to be like, having watched previous years XC races. As always, its steeper than it looks.
The sections where someone is going to be pedalling au-naturel above the limit I think is going to be minimal*. Or at least, such short duration that it will be a large effort for minimal gain. Maybe the occasional tactical overtake but as a general strategy I dont think it has the legs. Perhapsif Sagan is truly hundreds of watts better than the rest of the field it might work.
I dont know enough about ebikes to be able to say how, if at all, they will need to manage their batteries, and I dont know enough about the rules to know if battery swaps are permitted.
*possible exception of the start/finish. Will be interesting how they set the course up for this.
