Pace, time & distance
Why one pace gives you six training paces
Most pace calculators stop at a single conversion — pace in, finish time out. This one goes further: the moment you calculate a pace, it's used as your reference to generate your full training-pace set automatically, using the same percent-of-reference-pace relationships that established methods like Jack Daniels' VDOT system and the McMillan Running Calculator are built on. No second form, no separate tool — one result, six paces, because that's what you actually need to plan a week of training around a single race result or goal pace.
Finish-time matrix
Your pace translated into finish times across the most common race distances.
| Pace (min/km) | 5K | 10K | Half Marathon | Marathon |
|---|---|---|---|---|
| 4:00 | 20:00 | 40:00 | 1:24:19 | 2:48:38 |
| 4:30 | 22:30 | 45:00 | 1:34:52 | 3:09:44 |
| 5:00 | 25:00 | 50:00 | 1:45:22 | 3:30:44 |
| 5:30 | 27:30 | 55:00 | 1:55:51 | 3:51:42 |
| 6:00 | 30:00 | 1:00:00 | 2:06:20 | 4:12:40 |
| 6:30 | 32:30 | 1:05:00 | 2:16:49 | 4:33:38 |
| 7:00 | 35:00 | 1:10:00 | 2:27:18 | 4:54:36 |
Times assume an even, consistent pace throughout — real race pacing typically varies with terrain, fatigue and fuelling.
Performance-level benchmarks
| Level | 5K pace | 10K pace | Typical profile |
|---|---|---|---|
| Beginner | 7:00-8:30 /km | 7:15-8:45 /km | New to structured running, building a base |
| Recreational | 5:30-7:00 /km | 5:45-7:15 /km | Regular runner, a few races completed |
| Intermediate | 4:30-5:30 /km | 4:45-5:45 /km | Consistent training, sub-50 10K range |
| Advanced | 3:45-4:30 /km | 4:00-4:45 /km | Competitive club-level, structured plan |
| Elite | Under 3:15 /km | Under 3:20 /km | National/regional competitive standard |

Frequently asked questions
What's a good 10k pace?
For recreational runners, 6:00–7:00 /km (≈10–12 min/mile) is common. Sub-50-minute 10k requires roughly 5:00 /km.
How do I convert min/km to min/mile?
Multiply your min/km pace by 1.60934. A 5:00 /km pace is about 8:03 /mile.
How accurate is a pace calculated from a single run?
Fairly accurate for that specific effort, but pace naturally varies with terrain, fatigue, heat and fuelling — treat a single result as a snapshot rather than a fixed number, and use several runs to establish a genuine training pace.
Should I train at my race pace every session?
No — most structured plans mix easy pace (slower, most volume), tempo pace (moderately hard, sustained) and interval pace (faster, short bursts) rather than running every session at goal race pace, which raises injury risk and blunts adaptation.
Why does my pace feel different on a treadmill vs outdoors?
Treadmill belts assist your stride slightly and remove wind resistance, so outdoor pace at the same effort is often 5-10 seconds/km slower — many runners set a 1% incline on the treadmill to roughly offset this.
What pace should I use to predict a marathon time?
Race-specific fitness (not just easy-run pace) predicts marathon time best — a recent 10K or half marathon result, run through a race-time predictor, gives a more reliable marathon estimate than extrapolating from training pace alone.
