Work out race handicap instantly with clear inputs, formula shown and shareable results.
The handicap reduces the actual time by the allowance percentage, and the adjusted pace divides that net time by the race distance. Percentage handicaps scale with race length, which is why the same allowance is fair across a 5 km and a marathon while a fixed minute deduction is not.
Adjusted time
net time = actual time x (1 - allowance percentage)
Pace
pace per km = net time / distance in km
net time = actual time x (1 - allowance percentage). The handicap reduces the actual time by the allowance percentage, and the adjusted pace divides that net time by the race distance.
Percentage handicaps scale with race length, which is why the same allowance is fair across a 5 km and a marathon while a fixed minute deduction is not.
Enter actual finishing time, handicap allowance, race distance. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
