2. If applicable, enter the pace you expect to slow down to toward the end of the race. To get negative splits, enter the pace you expect to increase to rather than a slower pace. 

3. Enter the mile where you expect the fade to kick in. 

4. Click on Calculate now to get your readings.
 

 

To calculate from your target FINISH TIME

1. Enter your target time in hours and minutes. For the half-marathon the target time can also be entered just in minutes. 

2. Enter the amount of fade. This is how much you expect to slow down and can be entered as seconds per mile, or as a percentage. To get negative splits, enter the amount of fade as a negative value by preceding it with a minus sign. Select the type of fade calculation required.

4. Enter the distance (mile) where you expect the fade to kick in.

5. Click on Calculate now to get your readings.

Readings
  • OVERALL average mile pace regardless of fade or increase.
  • AVERAGE mile pace before your fade or increase mark.
  • AVERAGE mile pace after fade or increase occurs.
  • SPLITS for every  mile.
  • HALF-MARATHON split.
  • FINAL time based on calculated splits.
Cool eh? ...now go calculate!
