Calculate the pace needed for a target half marathon finish time.
Dividing the target time by the race distance gives the pace that must be held throughout. The halfway split is the checkpoint that reveals whether the pace is on track early enough to correct. The half marathon is the longest distance most runners can hold near threshold pace, which makes even pacing more forgiving than in a full marathon.
Half Marathon Pace
Pace = finish time ÷ the half marathon distance of 21.0975 km
