What a 15:00 5K predicts
Estimate| Distance | Estimated time |
|---|---|
| 10K | 31:16 |
| 10 miles | 51:47 |
| Half marathon | 1:09:00 |
| Marathon | 2:23:52 |
These are estimates from the Riegel formula, T2 = T1 × (D2 ÷ D1)^1.06. They assume you’ve trained for the other distance, so treat them as a guide, not a promise.
Under 17 minutes, the 5K is hard from the gun
Sub-17 is fast club running. The race is short enough that you start hard and hold on, so training leans on intervals at 5K pace and quicker, plus threshold runs.
A long warm-up with strides matters more here than in any longer race. You need to be ready to run fast from the first step.
Watch your second kilometre. That’s where a start that was too quick shows up.
Pace questions runners ask
- What pace do I need for a 15:00 5K?
- A 15:00 5K is 3:00/km (4:50/mi), 20.0 km/h, held for the whole race.
- What treadmill speed is 15:00 5K pace?
- Set the treadmill to 20.0 km/h or 12.4 mph to run 3:00/km (4:50/mi).
- Where should I be at halfway in a 15:00 5K?
- With even pacing you pass halfway in 7:30; with a negative split, a little later.
- What does a 15:00 5K predict for other distances?
- The Riegel formula estimates 31:16 for the 10K, 51:47 for the 10-mile race, 1:09:00 for the half marathon, 2:23:52 for the marathon, assuming you’ve trained for each distance.
