“It’s a about a 15.3 km climb,” said Kerrison. “Around 41.30 [in duration]. Chris’s average for the whole climb was 414w, and a VAM of 1602 Vm/h.”
VAM is a measure of climbing speed, measured in metres-per-hour. The biggest values ever seen in pro cycling, over sustained climbs, were in excess of 1800 Vm/h, from Lance Armstrong and Marco Pantani.
At the other end of the scale, the grupetto on a climb like the Col du Soudet would be more like 12-1300 Vm/h. 1600 Vm/h is much closer to the climbing speeds seen in the pre-EPO era – although accurate VAM data is not always easy to come by, since it’s frequently calculated from historic TV coverage.“Asymetric chain rings mean that our power values over-read by about 6%, so corrected for that, his power-to-weight was 5.78w/kg,” he continued. This means that Froome’s corrected average for the whole climb was more like 390w.
