This 15K pace chart links finish times from 48 minutes up to 2:00 with the pace required over 15 kilometres (about 9.32 miles), shown per kilometre and per mile alongside the matching treadmill speed. The 1:00, 1:15 and 1:30 rows are highlighted because they sit on the clean 4:00, 5:00 and 6:00 min/km marks.
Reading the chart
Locate your goal time on the left and read across. A 1:15:00 15K needs 5:00 min/km, about 8:03 min/mile at 12.0 kph, while breaking the hour requires 4:00 min/km or faster, roughly 6:26 min/mile. Every row is the finish time divided by 15 kilometres exactly, so nothing here is rounded to a convenient number. For a step-by-step walkthrough of the underlying formula, see how to calculate running pace.
Where the 15K fits
The 15K is a common tune-up distance in marathon and half marathon training blocks, long enough to test race-day fuelling and pacing discipline without the full recovery cost of a longer effort. It rewards the same even-effort approach as the longer distances: settle into goal pace early rather than banking time, since the back half will ask for it. A continuous run at target pace, building from 3 km up toward 8 km over several weeks, is a practical way to rehearse it.
Compare and predict
A recent 10K is a solid input for the race time predictor, which can estimate a 15K or half marathon time from it using Riegel's formula. Cross-check the pace here against the 10K pace chart and the half marathon pace chart, and use the pace calculator to convert any figure between units.
Frequently asked questions
What pace is a 1:15 15K?
A 1:15:00 15K works out to 5:00 min/km, about 8:03 min/mile. It is the same 5:00 min/km rate as a 25:00 5K held for three times the distance.
What pace do I need to break 1:00 for a 15K?
Sub-1:00:00 needs faster than 4:00 min/km, about 6:26 min/mile or quicker, sustained for the full 15 kilometres.
How long is a 15K, and how is this chart calculated?
A 15K is 15 kilometres, about 9.32 miles. Each pace is the finish time divided by 15 km, with the per-mile column using the exact 1.609344 km-per-mile factor.
