The climb · Spain
About Lagos de Covadonga
Lagos de Covadonga is dramatic from the start, a climb that announces itself with steep ramps and narrow, winding roads. The mountains of Asturias tower around you, with waterfalls and rugged peaks framing the ascent.
The gradient bites in sections, forcing careful breathing and concentration. Each hairpin seems to test your patience, but the scenery offers moments of distraction and inspiration.
Summiting is a triumph, a reward for both strength and willpower. This climb is for riders who thrive on challenge and appreciate the raw beauty of northern Spain.

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

Based on the 12.34 km elevation profile. Assumes steady power, with no stops, braking or drafting. Rounded to the nearest minute.
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.
