This nice little programme is written by © Axel Kohlmann to help runners to predict their race time by using a result achieved on a different distance.
Please note that ...
... every field has to be filled in. If your run is shorter than one hour please put in: 0 hours.
... the calculator is based on kilometers. It would produce wrong results if miles are used.
To help: 10miles = 16.109 K, half marathon = 21.096 K, marathon = 42.195 K
... decimal numbers are put in by using points, not commas (e.g. 42.195
