Pace and race times

One division for the pace, and one exponent for the prediction. The predictions reaching well past what you have actually raced are marked as such.

Your pace

Example

5:00/ km

8:03 per mile, or 12.0 km/h on a treadmill.

pace = 25:00 ÷ 5.00 km = 5:00 / km
10 km = 1500 × (10 ÷ 5.00) ^ 1.06 = 52:07

25:00, or 1:55:00 for over an hour.
