Climbing in big rin + high sustaining heart rate?
From 2:00 onwards, Pantani is out of the saddle really pushing it hard for like the whole mountain. I know these guys were on EPO, even Pantani was doing cocaine, but it still has to be challenging holding that pace up the mountain.
How do these guys sustain such a high heart rate climbing? I mean it has got to be high to put out that amount of power they do. Also, what gears are they climbing in? 53x16?
