Simon Warren’s Another 100 Greatest Cycling Climbs

At Millook, the Cornish coast supplies a sharp transition from the bottom of the valley to the road above. This is the ascent heading south-west, a little under a kilometre long, with tight bends carrying it up the hillside. The road gains height quickly, so the sea and lower valley begin to fall away almost as soon as the climbing starts.

There is little opportunity to make the effort uniform. The turns interrupt the line of the road, and the sustained steepness makes each change of direction part of the climb's character. Towards the upper end, the slope becomes less demanding and the pedals can turn more freely, though the short distance has already delivered a substantial effort. A glance back gives the ascent its scale: the coastline is close, but suddenly well below. Millook makes a strong impression in very little road.

03 / 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.

Based on the 0.94 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.
