Marathon Pace Calculator
Calculate your marathon pace and mile-by-mile splits. Enter goal time or current pace to plan your 26.2 mile race strategy with even or negative split options.
The marathon (26.2 miles / 42.195 kilometres) is the pinnacle of distance running — and pacing is its most technical element. Start too fast and you'll bonk. Nail your pace and you'll run a PR. This calculator gives you your required pace, a printable mile-by-mile split table, and a race strategy to match.
Marathon Pace Formula
Pace (min/mile) = Finish time (minutes) ÷ 26.219
Pace (min/km) = Finish time (minutes) ÷ 42.195
Example — targeting a 4:00:00 (4-hour) marathon:
- Pace per mile: 240 ÷ 26.219 = 9:09 min/mile
- Pace per km: 240 ÷ 42.195 = 5:41 min/km

Marathon Race Strategy: The 3 Approaches
Even splits (Recommended for first-timers)
Run every mile at exactly the same pace. Surprisingly hard to execute — the first miles feel very slow, which is psychologically uncomfortable.
Rule: If miles 1–3 feel too easy, you're doing it right.
Negative splits (Best for experienced runners)
Run the second half 1–3 minutes faster than the first half. The most common strategy for BQ attempts and PR races.
- Miles 1–8: 15–20 seconds per mile slower than goal pace
- Miles 9–16: Goal pace
- Miles 17–20: Goal pace or slightly faster if feeling strong
- Miles 20–26.2: Everything you have
Positive splits (What most runners do by accident)
Going out too fast in miles 1–10. Results in a dramatic slowdown in miles 18–22 — the dreaded "wall." The marathon wall (hitting the glycogen wall) happens when muscle glycogen is depleted. At around 75–80% of maximal aerobic capacity, muscles rely heavily on glycogen. A hard first half depletes it faster.
Fuelling Strategy by Finish Time
| Finish time | Gel/fuel timing | Water strategy |
|---|---|---|
| Under 3:00 | Miles 5, 10, 15, 20 | Every other aid station |
| 3:00–4:00 | Miles 5, 9, 13, 17, 21 | Every aid station |
| 4:00–5:00 | Miles 5, 9, 13, 17, 21, 24 | Every aid station + electrolytes |
| Over 5:00 | Every 45–60 min throughout | Every aid station, consider sports drink |
Take gels 2–3 minutes before aid stations so you can wash them down with water. Never try a new gel brand on race day — only use what you've trained with.
Predicting Marathon Time From Shorter Races
| 5K | 10K | Half marathon | Predicted marathon |
|---|---|---|---|
| 20:00 | 41:33 | 1:31:44 | 3:11:41 |
| 25:00 | 51:57 | 1:54:40 | 3:59:35 |
| 28:00 | 58:10 | 2:08:40 | 4:28:41 |
| 32:00 | 1:06:28 | 2:27:06 | 5:06:46 |
| 35:00 | 1:12:41 | 2:41:04 | 5:35:51 |
Predictions assume marathon-specific training including 18–20 mile long runs. Using a half marathon result is the most accurate short-distance predictor.
Frequently Asked Questions
What is the Boston Qualifying standard?
Boston Qualifying (BQ) standards vary by age and gender. For 2025: Men 18–34 need sub-3:00 (6:52/mile); Men 35–39 need sub-3:05; Women 18–34 need sub-3:30 (8:00/mile). Standards are published at baa.org. Getting a BQ time isn't enough — you typically need to run 2–5 minutes faster than the cutoff due to field size limits.
What is the marathon "wall" and how do I avoid it?
The wall (usually between miles 18–22) occurs when muscle glycogen is severely depleted and the body struggles to maintain pace. To avoid it: train with long runs of 18–20 miles, practise race-pace fuelling in training, start conservatively in the first half, and take gels or sports drink regularly throughout the race.
How long does it take to recover from a marathon?
The general guideline is one day of easy recovery per mile raced — 26 days. Most runners feel normal at 2 weeks but muscle damage at a microscopic level takes 3–4 weeks to fully repair. Running a marathon every 8 weeks year-round leads to accumulated fatigue and injury. Most coaches recommend 2–4 marathons per year maximum.
Should I run a tune-up race before my marathon?
Yes — a 10K or half marathon race 4–6 weeks before your marathon serves three purposes: it provides an accurate pace prediction, gives you race-day practice, and provides a confidence boost or a reality check for your goal pace. Don't race all-out — treat it as a strong tempo effort.
What is a good first marathon time?
For a first marathon, finishing is the primary goal. Finishing under 5 hours (pace: 11:27/mile) is considered a solid result. Most first-timers finish between 4:30 and 6:00. The most important advice: don't set a time goal for your first marathon. Set a strategy goal (run every mile, only walk aid stations) and let the time be whatever it is.
