Training plans Marathon
The sub-3:00 marathon
Running a sub-3:00 marathon means holding 4:16/km (6:52/mi) for 42.2 kilometres. Plan on 5–6 runs and 70–95km per week for around 16–20 weeks. Training happens at three speeds — easy mileage (5:11–5:46/km), tempo work near 4:00/km, and faster reps at about 3:45/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 4:16/km the opening kilometres should feel almost too easy; that restraint is what a 3:00 costs up front.
A typical week
Key session 1
Intervals — reps around 3:45/km (5K effort) with jog recoveries
Key session 2
Tempo — sustained comfortably-hard running near 4:00/km
Long run
The week's cornerstone at 4:41–5:11/km, adding 3:00-pace finishes as race day nears
Plus 3+ easy runs. All other runs sit at 5:11–5:46/km by design — accumulating volume without stealing from the key days.
Asked often
- What pace is a sub-3:00 marathon?
- 4:16 per kilometre, held for the full marathon. Racing the first half a touch inside 4:16 and finishing strong beats banking time every time.
- How long should I train for a sub-3:00 marathon?
- From a reasonable base, 16–20 weeks. Coming back from time off, add a re-ramp phase before the 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 marathon weeks around what you actually ran.

Built to get you under 3:00 — and to bend when life does
RunV builds your sub-3:00 plan around your week, then recalibrates it after every run — finished, cut short, or missed.
