Simon Warren’s Another 100 Greatest Cycling Climbs

White Shaw Moss is the steep northern approach from Deepdale, leaving the Dentdale side for the road towards Ingleton. This is the short, concentrated climb, rather than the much longer ascent from the south. Early bends introduce the hillside at close quarters, and the gradient soon makes clear that the valley is being left decisively behind. The selected route measures about 2.2 kilometres, with most of that distance contributing directly to the rise.

A brief easing breaks the lower climbing, but the harder work returns through the middle before the slope gradually moderates near the top. At roughly 10.3% overall, the ascent remains substantial even where it offers a little relief. The open upper country and views back towards Dentdale give the finish a sense of space that the turning lower road lacks. It is a compact route into the Dales uplands, with a notably serious middle section.

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

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

Rider weight (kg)

Bike + kit includes clothing, bottles and luggage.

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.
