5km Race Pace Calculator

The 5km is the sharpest test of running fitness — fast enough to hurt, long enough to punish poor pacing. Whether you're targeting a sub-20 breakthrough or building toward a triathlon run split, knowing your required pace per kilometre is the starting point.

Enter either your goal finish time or your goal pace per kilometre — the calculator works both ways, giving you your projected finish time, km/h speed and even splits throughout the race.
