About this calculator
An intermediate rider covering 80 km with 800 m of climbing and two rest stops should plan on about 5 hours (302 minutes): 3.2 hours of riding at 25 km/h, about 1.3 hours added for the climbing, and 30 minutes of stops. The calculator adds those three parts and scales the riding and climbing time for fitness and weather.
The formula
Time (minutes) = [distance ÷ (25 × fitness × weather) + elevation ÷ (600 × fitness) + stops × 0.25] × 60. The base pace is 25 km/h on flat roads and 600 m of climbing an hour. Fitness ranges from 0.7 for beginners to 1.8 for elite riders, and weather from 1.2 in ideal conditions to 0.6 in severe weather. Each stop adds 15 minutes.
Why climbing gets its own term
On a climb most of your power goes into lifting rider and bike against gravity rather than overcoming air resistance, so speed falls sharply. Physics-based cycling models, such as the one Martin and colleagues validated against power-meter data, combine aerodynamic drag, rolling resistance and the change in height; this calculator uses a simpler rule of thumb in the same spirit as Naismith's rule for hikers.
Planning food and drink
Use the estimate to plan fuel. Sports nutrition guidance, including the 2016 joint position of the Academy of Nutrition and Dietetics, Dietitians of Canada and the American College of Sports Medicine, supports carbohydrate during exercise lasting more than about an hour, typically 30 to 60 g an hour, and up to 90 g an hour for efforts longer than 2.5 to 3 hours. The table below turns ride time into a plan.
| Ride time | Carbohydrate per hour | Notes |
|---|---|---|
| Under about 1 hour | Usually not needed | Water is enough for most riders |
| About 1 to 2.5 hours | 30–60 g | Drinks, gels, bars or food |
| Over 2.5 to 3 hours | Up to 90 g | Glucose–fructose mixes absorb faster at high rates |
How to use
Enter the ride distance in km, the total elevation gain in meters and the number of planned stops, then choose your fitness level and the expected weather. The default, 80 km with 800 m of climbing, intermediate fitness, average weather and two stops, gives about 302 minutes. With a headwind (0.8) on a 60 km ride with the same climbing and stops, the result is about 290 minutes.
Frequently asked questions
How much time does climbing add to a ride?
At this calculator's base rate of 600 m an hour, every 100 m of climbing adds about 10 minutes for an intermediate rider, less for fitter riders. An 800 m day adds about 80 minutes on top of the flat-road riding time.
Which fitness level should I choose?
Pick the level whose flat-road speed matches yours: the base is 25 km/h, so beginner (0.7) corresponds to about 17.5 km/h, advanced (1.4) to about 35 km/h and elite (1.8) to about 45 km/h before weather. If your recent rides were slower, choose the lower level.
How much should I eat on a long ride?
For rides over about an hour, sports nutrition guidance supports roughly 30 to 60 g of carbohydrate an hour, and up to 90 g an hour for efforts longer than 2.5 to 3 hours, using drinks, gels or food you have practiced with. Drink regularly as well, more in hot weather.
