Bear Road, Brighton: Cycling Climb

The climb · United Kingdom

About Bear Road, Brighton

Bear Road climbs out of the Lewes Road valley towards Warren Road near the top of Race Hill. It is a direct way to discover the height hidden behind Brighton's streets: terraced housing lines part of the northern side, while cemetery grounds give the road a more open setting on the opposite side. The uphill line is easy to understand, with the ridge providing a clear destination above the houses.

The effort comes from staying on the rising road rather than negotiating a complicated succession of turns. As the housing thins towards the upper end, the route begins to feel connected to the open ground around Race Hill. It remains an urban climb throughout, but the transition from valley junction to ridge gives it a satisfying sense of progress. Bear Road makes a substantial hill out of an everyday city street.

03 / 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.

Based on the 1.47 km elevation profile. Assumes steady power, with no stops, braking or drafting. Rounded to the nearest minute.

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.
