Power (expressed in watts) = strenght x speed
Melle, for example, kicked an average power of 284 Watts. And at the second test during last weekend we were impressed by Erik because of his results: 290 Watts, an improvement of 12 watts compared to the first test!
But what is the significance of such an average power? What does this say about our current form and how do we relate to the great ones of the earth?
To provide insight into this, we look at some values of a person weighing 75 kg that is cycling on a flat road in windless weather.
Of course, it is never windless outside, in addition the rolling resistance, weight of the bike and the gradient percentage also play a role.
To achieve a speed of 25 km on an ascent with a gradient of 5%, 394 watts is needed. Now we’re talking!
Driving behind another cyclist requires between 30 and 50% less power.
We look and compare two Italian heroes from the past and present, Vincenzo Nibali en Fausto Coppi… Funny detail: Nibali was the winner of the Cima Coppi in last year’s Giro.
We compare them with one of our fastest men, Erik:
Nibali kicked 473 watts away at an acceleration for four minutes, with a peak of 1000 watts!!
As far as we know, the Italian heroes never climbed the Mauna Kea. So we take the Cima Coppi (the Stelvio) to calculate.
