Beginner Marathon Training Plan: 16 Weeks, Four Runs a Week
A 16-week beginner marathon plan for 4:00 to 6:00 finishers: four runs a week, peak 51 km, long runs up to 23 km. Free, built from your own race time.
A beginner marathon plan runs 16 weeks at four runs a week, peaks at about 51 km, and builds the long run to 23 km. It fits runners heading for a 4:00 to 6:00 marathon: roughly a 25 to 38 minute 5k, or a half marathon between about 1:56 and 3:00.

The sample runner has a 27:00 5k and four free days a week:
- Base, weeks 1 to 6. From 32 to 41 km a week. One short quality session: an 8-minute marathon-pace plus 8-minute threshold progression, cruise intervals of 3 × 1 km, a 15-minute tempo. Long runs grow from 14 to 19 km.
- Build, weeks 7 to 10. Two quality days now, threshold plus a small VO2max dose such as 3 × 3 minutes or 6 hill repeats of 75 seconds. Long runs reach 22 and 23 km. A 5k time trial in week 10 checks your progress.
- Peak, weeks 11 to 14. Marathon pace arrives: 4 to 5 km mid-week runs, 1 km alternations, and 23 km long runs that finish with 8, 10, then 12 km at goal effort.
- Taper, weeks 15 and 16. A 15 km dress rehearsal with 6 km at marathon pace, then an easy race week.
Every fourth week drops to about 75 % of the week before.
Who counts as a beginner
Beginner here means fitness, not experience. The plan reads a recent race with Jack Daniels' VDOT, one number that sets every training pace, and predicts your marathon from it. A predicted marathon slower than 4:00 is the beginner band. A 27:00 5k is VDOT 35 and predicts about 4:16.
| Marathon finish | Race pace | Easy | Threshold | Interval |
|---|---|---|---|---|
| 4:00 | 5:41 | 6:06–7:17 | 5:19 | 4:53 |
| 5:00 | 7:07 | 7:35–9:00 | 6:38 | 6:05 |
| 6:00 | 8:32 | 9:04–10:41 | 7:57 | 7:19 |
Your easy pace is 25 seconds to about two minutes per km slower than marathon pace, depending on where you sit in the band. That gap is the whole point: 80 % of this plan is easy running, and easy has to feel easy.
No recent race? Pick the beginner level in the generator instead. Week 1 then starts with a 5k time trial, and every pace appears once you enter the result.
Why the long run stops at 23 km
Many beginner plans put a 32 km run three weeks before the race. At a 7:00 easy pace that is close to four hours on your feet, longer than a fast runner's entire marathon. The fatigue from a run that long costs more training than it builds.
This plan limits the long run to 45 % of the week and to three hours, whichever comes first. Daniels caps long runs for higher-mileage runners at 150 minutes for the same reason. For the sample runner the limit lands at 23 km, about 2 hours 35 minutes. The race itself covers the rest, on fresh legs after the taper.
What replaces the missing kilometres:
- Marathon pace at the end of the long run. Running 8 to 12 km at goal pace on tired legs teaches the exact skill race day asks for.
- Consistency across 16 weeks. Volume never jumps more than 10 % between loading weeks. Nielsen (2014) found runners who added more than 30 % over two weeks got injured more often than those under 10 %.
- A two-week taper. Bosquet's meta-analysis found performance gains peak with about two weeks of tapering and a 41 to 60 % cut in volume.

FAQ
Can I train for a marathon on three runs a week? Yes. The peak stays at 50 km, because the two other runs get longer. Four days spreads the load and is easier on the body.
How long should my longest run be as a first-time marathoner? In this plan, 45 % of your peak week and no more than three hours. Across the beginner band that works out at about 18 to 23 km.
Should I run the marathon at the pace in the table? Use it as the starting point. If your week-10 time trial comes in faster, enter it and your marathon pace updates.
Is 16 weeks long enough for a beginner? If you run about 25 to 30 km a week today, yes. The plan never starts below half its peak, so build to 25 km first if you are lower. With more time, choose 20 or 24 weeks and the extra weeks go into base.

R · Repetition. Speed, economy and running power; short fast reps with full recovery. RPE 9–10, fast and controlled.
- Your VDOT of 49.8 is a single number that captures current running fitness (a 'VO₂max' adjusted for running economy). Every training pace is derived from it.
- VDOT comes from one recent, hard race or time trial. Use a result you raced all-out, ideally 5 km or longer; a half-marathon or 10 km gives the most stable estimate.
- Switch the units toggle to read paces per mile. As you get fitter, re-race; your VDOT and all paces will update.
- These are Daniels’ discrete training paces (E, M, T, I, R), not continuous zones: you run at each one for a specific purpose. The gaps between the harder paces (T, I and R) are intentional, not a glitch.
