Training plans Half marathon
The sub-2:15 half marathon
Running a sub-2:15 half marathon means holding 6:24/km (10:18/mi) for 21.1 kilometres. Plan on 4–5 runs and 37–53km per week for around 9–13 weeks. Training happens at three speeds — easy mileage (7:19–7:54/km), tempo work near 6:07/km, and faster reps at about 5:52/km. Whether that timeline is realistic depends on your current fitness — the honest test is a recent race result, not ambition.

Even splits shown — at 6:24/km the opening kilometres should feel almost too easy; that restraint is what a 2:15 costs up front.
A typical week
Key session 1
Intervals — reps around 5:52/km (5K effort) with jog recoveries
Key session 2
Tempo — sustained comfortably-hard running near 6:07/km
Long run
The week's cornerstone at 6:49–7:19/km, adding 2:15-pace finishes as race day nears
Plus 2+ easy runs. All other runs sit at 7:19–7:54/km by design — accumulating volume without stealing from the key days.
Asked often
- What pace is a sub-2:15 half marathon?
- 6:24 per kilometre, held for the full half marathon. Racing the first half a touch inside 6:24 and finishing strong beats banking time every time.
- How long should I train for a sub-2:15 half marathon?
- From a reasonable base, 9–13 weeks. Coming back from time off, add a re-ramp phase before the half marathon block rather than compressing it.
- What happens if I miss training weeks?
- Missed weeks are where PDF plans fail: the schedule marches on without you. RunV rebuilds the remaining half marathon weeks around what you actually ran.

Built to get you under 2:15 — and to bend when life does
RunV builds your sub-2:15 plan around your week, then recalibrates it after every run — finished, cut short, or missed.
