Simon Warren’s Cycling Climbs of Scotland

On western Mull, the B8035 leaves the southern shore of Loch na Keal near Gribun and climbs inland towards the road to Loch Scridain. Ben More Road is a climb through this coastal landscape, rather than an ascent of the mountain itself. The ascent rises for about 3.6 kilometres, gaining roughly 135 metres, with the road drawing away from the water into the higher ground behind the coast.

The surrounding cliffs and upland slopes give the ascent more scale than its modest height gain suggests. Its interest lies in that change of setting, from the edge of the sea loch to the road above Gribun. Access is currently restricted: the council's September 2026 update says the B8035 between Kinloch and Gruline remains closed to all public traffic because of rockfall hazards.

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.
