Simon Warren’s Cycling Climbs of Scotland

South of Fairlie, the turn inland from the A78 starts a sharp change from the Clyde coast to the moor above it. Fairlie Moor Road climbs eastwards towards the upland crossing in the direction of Dalry, with bends lifting it away from the shore. The ascent covers roughly 3.3 kilometres and gains about 240 metres, most of that height coming in the earlier part of the climb.

As the coastal ground falls behind, the setting becomes more open and the road has room to reveal the hillside ahead. The upper section is gentler overall, though small changes in gradient prevent it from feeling entirely uniform. Views back towards the Firth of Clyde give the effort a clear geographical reward: the coast you have left remains part of the landscape. It is a climb defined by that transition, with the hardest work preceding the broadest surroundings.

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.
