How it works
Arithmetic, not physiology. Distance is locked at 8.000 km (4.97097 mi). Pace = time / distance. This is even 8K race pace, not race-equivalence. For a 5K→8K or 10K→8K estimate, use the race time predictor (Riegel). This page does not clone VDOT or McMillan tables.
- pace = time / 8.000 km
- 8K = 8.000 km = 4.970969538 mi
- 1 mile = 1.609344 km

FAQ
What pace for a 40:00 8K?
A 40:00 8K 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 and a 1:15:00 15K. Distance is locked at 8.000 km (4.97 mi). There is no Calculate button; pace updates live.
What is 8K race pace?
8K race pace is even pace for 8.000 kilometers. A 32:00 8K is 6:26/mi · 4:00/km. A 48:00 8K 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 an 8K?
An 8K is 8.000 kilometers, which is 4.97 miles (exactly 4.970969538 mi using 1 mile = 1.609344 km). SplitLab locks this page to that distance so a 40:00 finish is 8:03/mi.
What are even-pace 8K splits?
A 40:00 8K hits every kilometer on the 5:00 clock: 5:00, 10:00, … 40:00. Halfway (4K) is 20:00, the 5K mark is 25:00, and mile 1 is 8:03.
Does this predict an 8K from a 5K or 10K?
No. This page is even-pace arithmetic for 8.000 km. It does not estimate an 8K 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).
