Calculate training paces
Use a recent race result to estimate practical training pace ranges.
Use these as starting ranges. Recovery, terrain, heat and accumulated fatigue should change the pace you actually run.
Calculate training paces from a recent race
The Training Pace Calculator converts a recent race result into practical pace ranges for easy running, steady aerobic work, tempo sessions, threshold training, intervals and short repetitions.
Rather than asking you to guess a target pace, the calculator starts with demonstrated race fitness. Enter a recent 5K, 10K, half marathon or marathon result, then choose minutes per kilometre or minutes per mile.
How to use the Training Pace Calculator
- Select the distance of your recent race.
- Enter your finish time.
- Choose minutes per kilometre or minutes per mile.
- Review the six suggested training pace ranges.
Use a recent race completed at a genuine, controlled effort. A current result is usually more useful than an old personal best that no longer reflects your present fitness.
What each training pace means
| Training pace | Primary purpose |
|---|---|
| Easy / recovery | Conversational running, recovery and low-stress aerobic mileage |
| Steady | Controlled aerobic running that is quicker than easy pace |
| Tempo | Sustained, comfortably hard running |
| Threshold | Focused work near the pace you could hold for roughly one hour |
| Interval | Hard aerobic repetitions with recovery between efforts |
| Repetition | Short, fast and relaxed work with full control of form |
Worked example: training paces from a 45-minute 10K
A runner who completes 10K in 45:00 would receive approximately these pace ranges:
| Training type | Pace per km |
|---|---|
| Easy / recovery | 5:19–6:05 |
| Steady | 4:57–5:19 |
| Tempo | 4:41–4:57 |
| Threshold | 4:27–4:41 |
| Interval | 4:03–4:25 |
| Repetition | 3:41–4:03 |
These are ranges, not fixed instructions for every run. Use the slower end when tired, on hills or in warm conditions. Use the quicker end only when the session, terrain and recovery level support it.
How the calculator derives the ranges
The calculator starts with the average pace from your submitted race result and applies percentage-based ranges around that pace. Faster training categories sit closer to or above race pace, while easy and steady running use a slower range.
This is a practical pace guide, not a laboratory measurement of lactate threshold, VO₂ max or heart-rate zones. Two runners with the same race result may still respond differently because of training history, terrain, fatigue and running economy.
How to apply the training paces
- Keep easy days genuinely easy and conversational.
- Use steady pace for controlled aerobic mileage, not for recovery runs.
- Use tempo and threshold ranges for sustained efforts or longer repetitions.
- Use interval and repetition ranges for shorter, structured work with suitable recovery.
- Adjust pace for hills, heat, wind, trail surfaces and accumulated fatigue.
- Avoid turning every run into a test of whether you can hit the fastest number in the range.

Frequently Asked Questions
Which race result should I use?
Use a recent result from an accurately measured race completed at a strong effort. Choose the result that best reflects your current fitness rather than your fastest result from several years ago.
How recent should the result be?
A result from the last several weeks is usually suitable, provided your training and fitness have not changed significantly since then.
Why does my easy pace feel too slow or too fast?
Easy pace varies with fatigue, heat, hills and training background. Treat the range as a guide and prioritise relaxed, conversational effort over forcing a precise number.
Do these paces work for hills or hot weather?
Use effort rather than exact pace when conditions change. Hills, heat, wind and technical surfaces can make the correct training effort slower than the calculator suggests.
How often should I recalculate my training paces?
Recalculate after a representative race or when your fitness has clearly changed. There is little value in adjusting the ranges after every normal training run.
What is the difference between tempo and threshold pace?
Tempo running is generally controlled and sustainable for longer blocks. Threshold pace is usually quicker and closer to the hardest effort you could sustain for around one hour.
