Estimation of cycling power

To reach a given speed, a cyclist must be able to produce a sufficient power, equal to the sum of powers required to overcome three types of resistances:

• Resistance of friction

• Resistance of the air

• Resistance of gravity

In the following calculator, an instant speed gives an instant power and a mean speed gives a mean power.

For example, the mean speed of a continuous maximal effort during 7 min approximately (climbing preferably) allows evaluating the Maximum Aerobic Power (MAP).

Auxiliaries for calculation:

• Speed

• Mean speed

• Slope
