Question: An elite Tour de France cyclist can maintain an output power of 440W during a sustained climb.
Part I: At this output power, how long would it take an 81kg cyclist (including the mass of his bike) to climb the famed 1100-m-high Alpe d'Huez mountain stage? Neglect any friction.
If possible just a brief explanation how you got the answer? Thanks.
