## Race Predictions

Based on your **5km time of 39:57** we can use the equation *T _{2} = T_{1} x (D_{2}/D_{1})^{1.06}* to predict your finish times for longer distances.

**5km**– 39:57**10km**– 1:23:18**Half Marathon**– 3:03:47**Marathon**– 6:23:10

This prediction formula will be more accurate for distances close to 5km, so the 10km prediction time of 1:23:18 will be more attainable and relevant than a full marathon of 6:23:10.

The equation *T _{2} = T_{1} x (D_{2}/D_{1})^{1.06 }*was published by Peter Riegel in 1977 where

*T*is your 5km time and

_{1}*D*is the 5km distance, and

_{1}*T*and

_{2}*D*are your predicted time and distance.

_{2}## How do you compare?
