Training plans 10K
The sub-40:00 10K
A sub-40:00 10K works out at 4:00/km (6:26/mi), held for the full distance. Typical preparation is 9–13 weeks of 50–65km a week, spread over 5–6 sessions. The work splits into three paces: easy volume at 4:55–5:30/km, threshold running near 4:05/km, and interval reps around 3:50/km. A recent race time is the truest guide to whether this goal fits this season.

These are dead-even splits — going out quicker than 4:00/km is the most common way a 40:00 slips away in the final quarter.
A typical week
Key session 1
Intervals — reps around 3:50/km (5K effort) with jog recoveries
Key session 2
Tempo — sustained comfortably-hard running near 4:05/km
Long run
The week's cornerstone at 4:25–4:55/km, adding 40:00-pace finishes as race day nears
Plus 3+ easy runs. The remaining runs stay genuinely easy (4:55–5:30/km); they carry the volume the key sessions are built on.
Asked often
- What pace is a sub-40:00 10K?
- 4:00 per kilometre, held for the full 10K. Even or slightly negative splits protect a 40:00 far better than a fast start.
- How long should I train for a sub-40:00 10K?
- From a reasonable base, 9–13 weeks. Start from where your running actually is: a recent race time sets the 10K timeline better than the calendar does.
- What happens if I miss training weeks?
- A static plan quietly breaks — every later week assumes fitness you didn't build. An adaptive plan like RunV's re-ramps volume and recalibrates paces so the 40:00 goal stays honest.

The engine behind your sub-40:00
RunV builds your sub-40:00 plan around your week, then recalibrates it after every run — finished, cut short, or missed.
