Simon Warren’s Cycling Climbs of Scotland

A climb above the Dornoch Firth, Struie Hill takes the road inland from its northern end towards the higher moorland. The lower approach passes through trees, giving the opening part a more enclosed feel than the landscape waiting above. Beyond the narrow bridge, a sharper bend introduces more purposeful climbing, and the road continues upwards past the viewpoint. The changing outlook helps make an ordinary stretch of road feel like a distinct ascent.

The measured climb is about 3.8 kilometres, averaging roughly 5.1%. It is substantial enough to find a rhythm, but the steeper change in the lower part prevents the effort from feeling entirely uniform. As the trees give way, the firth becomes the defining feature of the view, and the road's inland destination begins to make sense. Struie is an understated climb, with the shift from woodland to a wider horizon doing much of the work.

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.
