Quinag gives this climb its scale long before the gradient becomes the main concern. Heading south on the A894 from the Kylesku side, the road rises beside the mountain towards the high ground above Loch Assynt. Broad slopes and the mountain's broken outline make the strip of tarmac feel small in the landscape. The ascent runs for about 5.7 kilometres, with enough continuity to become a proper stretch of climbing rather than another brief rise in a coastal ride.
The gradient averages around 4.1%, so the character is more sustained than abrupt. Height accumulates progressively as the road works towards the pass, and the surrounding country remains as much a part of the ride as the effort itself. This is an ascent to settle into and watch unfold, with a mountain backdrop that gives relatively moderate climbing an unusually strong sense of place.

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.
Use your intended climbing effort, rather than FTP unless you can hold it for the predicted duration.

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.
