La Redoute leaves Sougné-Remouchamps on the slopes above the Amblève valley, beginning on a relatively manageable town approach before the road turns upwards beyond the motorway underpass. The ascent becomes more demanding through its middle, where the hillside gives the climb a much sharper character than the opening suggests. This entry follows the full selected rise, including the easier continuation above the main ramp.
About two kilometres of road gain roughly 180 metres. The work is unevenly shared: the stronger middle slopes ask substantially more than the lower approach, while the gentler final section offers a chance to feel the height already gained. The climb's shape is part of its attraction, moving from a town departure to a sustained hillside effort and then a less severe ending. La Redoute remains a convincing ascent even when considered simply as a road out of the valley.

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.
