Finish Time Calculator

Predict a race time based on your times at other distances.

Split distance already run: Miles Kilometres Metres Yards
Time for split hours mins secs
Total race distance Miles Kilometres Metres Yards or Select Run Type Marathon Half Marathon 10km 5km

NOTE: For best results use race distances that are close in length. For example using a 5K time to predict a 10K time will yield a realistic estimated 10K finish time goal. Using a 5K time to predict a full marathon would not. Many runners use the following formula to predict an accurate full marathon goal time based on a half marathon finishing time: Half Marathon Time X 2 + 10 minutes = Full Marathon estimated time
