Bike Pace Calculator

Quick answer

The bike pace calculator turns a cycling distance and time into average speed and pace per kilometre and mile – for common distances from 10 km to 300 km, including the 180 km Ironman bike leg.

Average speed
28.57
Pace per km
2:06
Pace per mile
3:23

Cyclists usually think in speed, but pace (minutes per km or mile) makes it easy to plan a long ride or the bike leg of a triathlon.

How to use the Bike Pace Calculator

  1. Distance
  2. Custom distance
  3. Riding time – hours
  4. minutes
  5. seconds

Results update as you type, every field has its own unit menu, and everything is calculated in your browser.

How it works

Choose the distance (or enter your own) and the riding time.

Inputs explained

Field What to enter
Distance Choose one: 10 km, 20 km, 40 km (Olympic triathlon), 50 km …
Custom distance Units: km, mi, m, yd
Riding time – hours A number
minutes A number
seconds A number

What each result means

  • Average speed = [d]÷([Riding time – hours]×3600 + [minutes]×60 + [seconds])
  • Pace per km = ([Riding time – hours]×3600 + [minutes]×60 + [seconds])÷60÷([d]÷1000)
  • Pace per mile = ([Riding time – hours]×3600 + [minutes]×60 + [seconds])÷60÷([d]÷1609.344)

Example values

How the main result changes when Custom distance changes and everything else stays at the example values above:

Custom distance (km) Average speed (km/h)
30 28.57
45 28.57
60 28.57
75 28.57
90 28.57
120 28.57

Formula

Speed = distance ÷ time · Pace = time ÷ distance

Worked example

Inputs — Distance: 100 km; Riding time – hours: 3; minutes: 30; seconds: 0.
Results — Average speed = 28.57 km/h; Pace per km = 2:06; Pace per mile = 3:23.

Key terms

Pace
Time per unit of distance.
