What a 48:00 10K predicts
Estimate| Distance | Estimated time |
|---|---|
| 5K | 23:01 |
| 10 miles | 1:19:29 |
| Half marathon | 1:45:54 |
| Marathon | 3:40:49 |
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.
Sub-50 is a pacing job
Under 50 minutes is a common target once finishing a 10K feels comfortable. Settle into goal pace by the first kilometre marker and check it every kilometre after that.
One session a week at or just under goal pace, plus regular easy runs, builds most of the speed you need.
If the course has a water station, a mouthful is plenty.
Pace questions runners ask
- What pace do I need for a 48:00 10K?
- A 48:00 10K is 4:48/km (7:43/mi), 12.5 km/h, held for the whole race.
- What treadmill speed is 48:00 10K pace?
- Set the treadmill to 12.5 km/h or 7.8 mph to run 4:48/km (7:43/mi).
- Where should I be at halfway in a 48:00 10K?
- With even pacing you pass halfway in 24:00; with a negative split, a little later.
- What does a 48:00 10K predict for other distances?
- The Riegel formula estimates 23:01 for the 5K, 1:19:29 for the 10-mile race, 1:45:54 for the half marathon, 3:40:49 for the marathon, assuming you’ve trained for each distance.
