How we work this out
A single division, then a set of race distances so the number means something. If you run in miles, the headline follows your unit and the race distances are still shown in their official metric lengths.
Step by step
- Convert your distance to kilometres if needed.
- Divide the purchase price by the distance to get cost per kilometre.
- Multiply by 5, 10, 21.0975 and 42.195 for the standard race distances.
What this does not claim
- We do not assume a replacement mileage. There is no universal number of kilometres a running shoe should last, and inventing one would change your result for no good reason.
- Price is what you paid. Resale value, warranty replacements and the second pair you bought on sale are not included.
- Half marathon and marathon distances are the official World Athletics lengths.
