Quick Answer
Most first-time marathoners finish in 4:30–5:30. Sub-5:00 is a solid beginner goal. Sub-4:30 is a strong first marathon. Sub-4:00 is excellent. The overall average across all runners is roughly 4:30 (men ~4:21, women ~4:48). Finishing at any pace puts you in the tiny fraction of people who’ve ever completed a marathon.

| Finish Time | Pace / Mile | Pace / Km | Level |
|---|---|---|---|
| 3:30:00 | 8:00 | 4:58 | Very strong first marathon (experienced athlete) |
| 3:45:00 | 8:35 | 5:19 | Excellent beginner |
| 4:00:00 | 9:09 | 5:41 | Strong beginner / sub-4 goal |
| 4:15:00 | 9:44 | 6:02 | Good beginner |
| 4:30:00 | 10:18 | 6:24 | Typical trained beginner (around average) |
| 4:45:00 | 10:52 | 6:44 | Comfortable beginner |
| 5:00:00 | 11:27 | 7:06 | Solid first marathon |
| 5:30:00 | 12:35 | 7:49 | First-timer / run-walker |
| 6:00:00 | 13:44 | 8:32 | Run-walker / completing the distance |
The highlighted rows (4:00, 4:30, 5:00) represent the three most common beginner targets. Pick the one that aligns with your half marathon pace — if you can run a half in 1:50–2:00, sub-4:00 is realistic. If your half is 2:15–2:30, aim for 4:30–5:00.
Average Marathon Times by Age and Gender
These include all runners, not just beginners. First-timers should expect to finish 15–30 minutes slower than these averages.

| Age Group | Men (Average) | Women (Average) |
|---|---|---|
| 18–24 | 4:10–4:30 | 4:40–5:00 |
| 25–29 | 4:05–4:20 | 4:30–4:50 |
| 30–34 | 4:00–4:15 | 4:25–4:45 |
| 35–39 | 4:05–4:20 | 4:30–4:50 |
| 40–44 | 4:10–4:30 | 4:35–4:55 |
| 45–49 | 4:15–4:35 | 4:45–5:10 |
| 50–54 | 4:25–4:50 | 4:55–5:25 |
| 55–59 | 4:35–5:05 | 5:10–5:40 |
| 60–64 | 4:50–5:25 | 5:25–6:00 |
| 65+ | 5:10–6:00+ | 5:50–6:30+ |
The 30–39 age bracket produces the fastest averages. After 50, times increase gradually — but a well-trained 60-year-old still finishes comfortably within most course time limits (typically 6–7 hours).
How to Predict Your Marathon Time
The most reliable predictor is your recent 10K time or half marathon time:
👉 Swipe to view full table
| Your Recent Race | Multiply By | Example | Predicted Marathon |
|---|---|---|---|
| Half marathon | × 2.1–2.2 | 2:00 half | ~4:12–4:24 |
| Half marathon | × 2.1–2.2 | 2:15 half | ~4:43–4:57 |
| 10K | × 4.6–4.8 | 55:00 10K | ~4:13–4:24 |
| 10K | × 4.6–4.8 | 65:00 10K | ~4:59–5:12 |
| 5K | × 9.5–10.0 | 28:00 5K | ~4:26–4:40 |
Use the higher multiplier if this is your first marathon — the final 10 km is where first-timers typically slow down. If you’ve done a structured training plan with long runs up to 32–35 km, you’ll likely beat these predictions.

What Matters More Than Your Time
For your first marathon, the primary goal should be finishing healthy and enjoying the experience. The time on the clock matters far less than crossing the finish line with a smile — and having a body that recovers well enough to want to do it again.
Common first-marathon mistakes that hurt finish times: starting too fast (adrenaline is real), skipping in-race fuelling (you need 30–60g of carbs per hour after the first hour), and insufficient long-run training (your longest run should reach at least 30–35 km before race day).
Get these basics right and your time will take care of itself. Your second marathon is where you chase the clock — your first is where you learn the distance.
Our marathon coaching programmes give you a 16–20 week training plan with weekly long runs, pacing targets, fuelling strategy, and race-day preparation — all personalised to your current fitness and goal time.
