How it works

Arithmetic, not physiology. Distance is locked at 3.000 km (1.86411 mi). Pace = time / distance. This is even 3K race pace, not race-equivalence. For a 5K→3K or mile→3K estimate, use the race time predictor (Riegel). This page does not clone VDOT or McMillan tables.

  • pace = time / 3.000 km
  • 3K = 3.000 km = 1.864113576 mi
  • 1 mile = 1.609344 km

FAQ

What pace for a 15:00 3K?

A 15:00 3K is 8:03 per mile, or 5:00 per kilometer, at even pace. That is the same even-pace band as a 25:00 5K and a 40:00 8K. Distance is locked at 3.000 km (1.86 mi). There is no Calculate button; pace updates live.

What is 3K race pace?

3K race pace is even pace for 3.000 kilometers. A 12:00 3K is 6:26/mi · 4:00/km. An 18:00 3K 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 3K?

A 3K is 3.000 kilometers, which is 1.86 miles (exactly 1.864113576 mi using 1 mile = 1.609344 km). SplitLab locks this page to that distance so a 15:00 finish is 8:03/mi.

What are even-pace 3K splits?

A 15:00 3K hits every kilometer on the 5:00 clock: 5:00, 10:00, 15:00. Halfway (1.5K) is 7:30, and mile 1 is 8:03.

Does this predict a 3K from a 5K or mile?

No. This page is even-pace arithmetic for 3.000 km. It does not estimate a 3K from another race, and it is not VDOT or McMillan. For a fatigue-based estimate from a recent race, use the race time predictor (Riegel).
