How does climbing affect ride time?

Climbing is modelled with VAM (velocità ascensionale media — your average rate of ascent in metres per hour). Extra climbing time = elevation gain ÷ VAM, added to your flat-distance time. This is the cycling version of Naismith's rule described by Cicerone. The default rate of 4.8 seconds per metre corresponds to a VAM of 750 m/h, typical of a recreational-to-club rider. Strong climbers (VAM ~1000-1500 m/h) climb faster, so set a lower seconds-per-metre value in Advanced; loaded tourers (VAM ~400 m/h) should set a higher one.

Should I include cafe stops?

Yes, include all planned stops — cafe breaks, photo stops, puncture allowances. A typical cafe stop is 15-30 minutes. Stops are added on top of your moving time and lower your overall average speed but not your moving average.

What flat speed should I enter?

Enter your typical no-stop average on flat terrain. For recreational riders this is roughly 18-25 km/h; most club riders sit at 25-32 km/h. This figure only covers the horizontal distance — the climbing time is added separately via the VAM model.

Total Distance

Total route distance from your GPS or route planner (Komoot, Strava, RideWithGPS).

Elevation Gain

Total ascent for the route — the cumulative metres climbed, from your route planner or head unit.

Average Flat Speed

Your typical no-stop average on flat roads (recreational 18-25 km/h, club riders 25-32 km/h).

Number of Stops

How many cafe, photo or mechanical stops you expect to make.

Average Stop Duration

Average length of each stop — a cafe stop is typically 15-30 min, a quick photo or refuel 2-5 min.

How We Calculate This

Ride Time Estimation

This uses the VAM method — the cycling equivalent of Naismith's rule (Cicerone) — where climbing time is added on top of the time to cover the flat distance.

Flat time = Distance ÷ Flat speed
Climb time = Elevation gain ÷ VAM, where VAM (m/h) = 3600 ÷ seconds-per-metre (default 4.8 s/m ≈ 750 m/h)
Moving time = Flat time + Climb time
Total time = Moving time + Stop time
