Simon Warren’s Cycling Climbs of Scotland

Riding back up Glen Etive towards the A82 puts the valley's gentle rise beneath your wheels. This climb covers the upper part of that return, heading north-east along the narrow road; it begins well above Loch Etive and does not include the whole journey from the loch. The River Etive and the mountain slopes around the glen provide the setting for a climb whose outline is more gradual than severe.

The section runs for 9.2 kilometres at an average of 1.7%. There are small rises and dips, but the road gains height overall towards the main-road junction. The middle part adds height more readily than the opening stretch, without turning the route into a sustained steep ascent. This is a climb to enjoy for the length of time it keeps you among the hills, with the effort spread over the journey. A quiet numerical outline for a large landscape.

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.
