Training plans Marathon
The sub-3:30 marathon
To break 3:30 for the marathon, you need an average of 4:59 per kilometre — 8:01 per mile — from gun to tape. Most runners get there on 63–87km per week across 5–6 runs, built over roughly 15–19 weeks. Expect three gears in the plan: 5:54–6:29/km for easy runs, roughly 4:38/km for tempo sessions, and 4:23/km for intervals. Your starting fitness decides whether the goal is a season away or further — judge it from a recent race, not a hopeful guess.

The table assumes level pacing; most runners land a 3:30 by holding two or three seconds per kilometre back from 4:59 early on.
A typical week
Key session 1
Intervals — reps around 4:23/km (5K effort) with jog recoveries
Key session 2
Tempo — sustained comfortably-hard running near 4:38/km
Long run
The week's cornerstone at 5:24–5:54/km, adding 3:30-pace finishes as race day nears
Plus 3+ easy runs. Everything else is easy running at 5:54–6:29/km — the volume that makes the hard days land.
Asked often
- What pace is a sub-3:30 marathon?
- 4:59 per kilometre, held for the full marathon. The runners who break 3:30 are usually the ones still passing people in the last quarter.
- How long should I train for a sub-3:30 marathon?
- From a reasonable base, 15–19 weeks. If you're returning from a break, rebuild first — squeezing a 15-week plan into less is how marathon builds break.
- What happens if I miss training weeks?
- If the plan can't adjust, missed weeks turn into injury risk or a blown goal. RunV recalibrates after every run — including the ones that didn't happen — to keep 3:30 in reach.

Sub-3:30, minus the guesswork
RunV builds your sub-3:30 plan around your week, then recalibrates it after every run — finished, cut short, or missed.
