About Coll de Soller

Collections

Climb out of Sóller on the northern side and the old pass road soon becomes a succession of hairpins. Each bend gives you another small piece of the hillside, with the valley dropping away behind. Around 7.6 kilometres of climbing makes this a proper effort, but the broadly steady gradient leaves room to enjoy the shape of the road. Settle into the turns rather than treating every short straight as a sprint.

There is pleasure in a climb that lets you keep pedalling without constant changes of gear. Sóller offers that rhythm, broken by the tighter corners and the temptation to look back. The satisfaction comes from joining the bends together smoothly, all the way to the pass. A good choice when you want the climb itself to be the occasion, rather than simply the price of reaching the other side.

04 / Your effort

How long would it take?

Enter the power you could hold for the whole climb. We calculate a moving time from the elevation profile and the forces you ride against.

Sustained power

W/kg

Use your intended climbing effort, rather than FTP unless you can hold it for the predicted duration.

Rider weight (kg)

Bike + kit weight (kg)

Bike + kit includes clothing, bottles and luggage.

Advanced settings

Defaults represent a road-bike scenario. Adjust these settings to match your tyres, drivetrain and riding position.

The science behind the calculation

For each part of the stored profile, we solve the steady-state cycling power equation for speed, then add distance ÷ speed across the climb. Gravity uses rider + equipment weight; available power is W/kg × rider weight. This uses the profile’s distance and elevation together, without mixing in another route’s metrics.

Power × efficiency = gravity + rolling resistance + air resistance + bearing losses

The resistance equations are adapted from Martin et al. (1998), Validation of a Mathematical Model for Road Cycling Power. Air density changes with profile altitude using NASA’s standard-atmosphere model. This calculator’s adaptation has not been independently validated.

It predicts travel at the power you enter, including on descents. It does not model acceleration, cornering, braking, traffic, wind, changing weather or fatigue. At altitude, choose power you can sustain there: thinner air reduces drag, but this model does not predict its effect on your ability to produce power. Profile quality and assumed equipment settings also affect the result.
