Hugo Koblet said:"Uphill sprints" is a broad term. Is it a Worlds Copenhagen or a Mur de Huy type sprint?
It has to be at least as difficult as Copenhagen. 400-500 m of climbing. Mur de Huy is the upper limit, more difficulty and it counts for explosive climbing. I don't know...Mur de Huy really is the crossover point, maybe even a bit too hard for that category.
