Asked by Noah

The record time for a Tour de France cyclist to ascend the 1100-m-high Alpe d'Huez is 37.5 min. The rider and his bike had a mass of 65 kg. At the average speed of the ride, the metabolic power to ride on level ground would be 700 W. To this, we must add the power to make the climb.

What was his total metabolic power? Express your answer in watts.

work done against g = m g h = 65 * 9.81 * 1,100 = 70,142Joules
time = 37.5 * 60 = 2250 seconds
power =701,415 / 2250 = 312 watts
312 + 700 = 1012
about a kilowatt :)
