Road Bike 44:00 [3]
Evening ride on my usual loop Zoo-Maur-Witikon. After reading a lot about VAM, Dr. Michele Ferrari's measurement of climbing performance, I was curious what kind of values I ride when riding fast but not really hard. So I measured the splits on both clims, the one up to the Zoo and the one up to Witikon. VAM basically expresses the number of meters climbed in one hour. For example, climbing a 500m hill in 30min equals a VAM of 1000m/h. VAMs are higher on steeper climbs, hence one can not compare them 1-to-1 but they give an indication. My correspnding VAMs were 1040 and 1140m/h, respectively. How does that compare to the climbing kings? Follwing a quote from Ferrari's observations during the Giro 07:
"In the hardest stage of this Giro 2007, it was a fierce battle since the first climb, and the endurance of the cyclists was toughly put to a test.
The pink jersey group, after the Passo S. Pellegrino, was climbing the Passo Giau (10km at 9% average gradient) at 1627 m/h, the Passo Tre Croci (8km at 7%) at 1450 m/h, while the last 4 km at 12% of the Tre Cime di Lavaredo were devoured by Di Luca in 15'30" (1780 m/h), with Simoni and Cunego at 1700 m/h, Schleck at 1672 m/h, and the excellent Mazzoleni and Riccò, both for a long time in breakaways, at 1650 m/h."
The highest VAM I was reading about was achieved in the Vuelta 2002 by Heras (1900m/h) while Amstrong was riding VAMs of about 1550-1750m/h during the TdFs. His VAMs are lower because passes tend to be flater in the TdF than in the Giro.
My values are even poorer since the climb today was very short compared to the cited hills. In order to reach a VAM of 1600 on the Witikon climb, I would have had to ride it in 6:15, instead, I had 8:45. When riding all-out, I'd probably only come slightly below 8min.
It's a long way to the top...
