About Yad Moss
Yad Moss is a long ascent through upper Teesdale, heading north-west towards the higher North Pennines. The selected route covers about 15.6 kilometres at an average gradient near two per cent, so the journey develops through distance rather than a single imposing slope. Much of the road rises gently, allowing the height gain to accumulate almost unnoticed when compared with the sharper climbs nearby. The scale comes from how long the upland approach continues.
The gradient is not uniform. Shorter steeper passages and small descents interrupt the general rise, giving the ride changes of pace without turning it into a succession of major banks. Higher up, the road becomes gentler again, with only a modest gain over the closing kilometres. The broad, remote setting gives time to appreciate the gradual move into higher country. Yad Moss is a climb whose length matters more than any one stretch of road.

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.

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.
