Formulas

Arithmetic, not physiology. Distance is locked at 15.000 km (9.32057 mi). Pace = time / distance. This is even 15K race pace, not race-equivalence. For a 10K→15K estimate, use the race time predictor (Riegel). This page does not clone VDOT or McMillan tables.

  • pace = time / 15.000 km
  • 15K = 15.000 km = 9.320567883 mi
  • 1 mile = 1.609344 km

FAQ

What pace for a 1:15 15K?

A 1:15:00 15K is 8:03 per mile, or 5:00 per kilometer, at even pace. That is the same even-pace band as a 50:00 10K. Distance is locked at 15.000 km (9.32 mi). There is no Calculate button; pace updates live.

What is 15K race pace?

15K race pace is even pace for 15.000 kilometers. A 1:00:00 15K is 6:26/mi · 4:00/km. A 1:30:00 15K is 9:39/mi · 6:00/km. Load a chip or type a finish time to see min/mile, min/km, and splits.

How many miles is a 15K?

A 15K is 15.000 kilometers, which is 9.32 miles (exactly 9.320567883 mi using 1 mile = 1.609344 km). SplitLab locks this page to that distance so a 1:15:00 finish is 8:03/mi.

What are even-pace 15K splits?

A 1:15:00 15K hits every kilometer on the 5:00 clock: 5:00, 10:00, … 1:15:00. The 5K mark is 25:00, 10K is 50:00, and halfway (7.5K) is 37:30. Mile 1 is 8:03.

Does this predict a 15K from a 10K?

No. This page is even-pace arithmetic for 15.000 km. It does not estimate a 15K from a 10K, and it is not VDOT or McMillan. For a fatigue-based estimate from a recent race, use the race time predictor (Riegel).
