35
To find the circumference of your rear wheel, you can either measure the wheel yourself using a tape
measure, or look up the value in an online calculator. For example, on this site you can find the
circumference using the diameter of the wheel and the thickness of the tyre:

For example, if your wheel size is 700c and the tyres are 25 mm thick, the circumference is 2111 mm.
This is the value you should enter.
Note: To get help on choosing which metrics you want to see during an activity, see Choosing
