The 3:30 marathon pace is 8:01 per mile or 4:59 per km. To finish under 3:30:00 you need an average slightly faster than that over the full 26.2 miles (42.195 km). At an even pace you reach 10 km in 0:49:46, halfway in 1:45:00 and mile 20 in 2:40:11.
The tool below is already set to a 3:30:00 goal, so the splits are ready. Change the goal time to test your own target, or switch to a negative split to see how the two halves change. It also gives the training paces for the goal and the race times that match it.
Everything is calculated in your browser, so nothing you type is uploaded, and the tool is free with no account or sign-up.

How to use the pace tool for this goal
- Check that Race is set to Marathon.
- Goal time is already 3:30:00. Type another time to see its pace and splits.
- Pick Pacing: Even, Negative split or Positive split. For the last two, set Difference between halves (%).
- Choose miles or km with the Units switch. Every pace and distance changes with it.
- Read the average pace and the split table: each row has the split time and the elapsed time.
- Use Print splits for a paper copy or Copy link to keep the exact result.
The split table has two columns that are easy to mix up. Split time is how long that one mile or km takes. Elapsed is the clock reading when you reach it, and it is the column to compare with your watch during the race. To compare goals, change only Goal time and watch the average pace and the Elapsed column update; nothing else needs resetting. Make a pace band for this time opens the pace band generator with the same race and goal. The tables scroll sideways inside their box on a small screen.
Everything runs in your browser and nothing you type is uploaded. Settings stay in the page address, so a copied link opens with the same goal. Prefer your phone? There is a RunPacePlan app for Android, with the iPhone version coming soon.
What training paces go with a 3:30 marathon goal?
For a 3:30:00 goal the easy pace is 9:13 to 10:25 per mile, the long run 8:49 to 10:01, threshold 7:28 and interval 6:43. These come from the same equations the training pace calculator uses, with the goal time as the input.
| Run type | Per mile | Per km |
|---|---|---|
| Easy | 9:13–10:25 | 5:43–6:28 |
| Long run | 8:49–10:01 | 5:28–6:13 |
| Marathon pace | 8:01 | 4:59 |
| Threshold | 7:28 | 4:38 |
| Interval | 6:43 | 4:11 |
Put your own recent race into the training pace calculator to see whether your current fitness points to the same paces.
What if I miss 3:30 by five minutes either way?
Five minutes changes the pace by about 11 seconds a mile. Use the row that matches the time you are really aiming for.
| Goal time | Per mile | Per km |
|---|---|---|
| 3:20:00 | 7:38 | 4:44 |
| 3:25:00 | 7:49 | 4:52 |
| 3:30:00 | 8:01 | 4:59 |
| 3:35:00 | 8:12 | 5:06 |
| 3:40:00 | 8:23 | 5:13 |
Which 5K, 10K and half marathon times match a 3:30 marathon?
A 3:30 marathon matches a 5K of about 22:00, a 10K of 45:37 and a half marathon of 1:41:06. These are estimates of equal fitness from the Daniels and Gilbert equations, not promises. A half marathon near 1:41 is a useful check before you commit to the goal.
Should I run even or negative splits for 3:30?
Even splits are the simplest plan: 8:01 for every mile. A negative split runs the second half faster. With a 2% gap the first half takes 1:46:04 and the second 1:43:56, which still adds up to 3:30:00. The slower start leaves room for mistakes, but it asks for a strong finish.
How many weeks and miles a week does a 3:30 plan need?
The marathon training plan generator builds plans from 12 to 24 weeks and sets marathon pace and threshold pace from your goal time. Its 16-week intermediate plan with four runs a week peaks at 39.6 miles (64 km) with a longest run of 19.8 miles (32 km). Enter 3:30:00 as the goal time to get paces on every run.
How do I start a 3:30 marathon?
Start at 8:01 per mile or a touch slower and let the first miles feel too easy. A fast start is a familiar reason for fading late. Check your elapsed time at 10 km (0:49:46) and at the half (1:45:00); if you are a minute ahead at the half, ease off rather than bank it. To see what a fast start costs, choose Positive split with a 2% gap: the first half takes 1:43:56 (about 7:56 per mile) and the second 1:46:04 (about 8:05 per mile). The early seconds look free, but you pay for them in the second half.
Who is a 3:30 marathon for?
It suits a runner who trains four or five days a week and whose half marathon is near the 1:41:06 that matches a 3:30 marathon. Holding 8:01 per mile for 26.2 miles asks for long runs well beyond two hours. If your best recent half marathon is much slower than that, the goal may need another training cycle.
What mistakes cost people a 3:30?
The first is starting faster than 8:01 and paying for it after mile 20. The second is treating 3:30:00 as “under 3:30”: a GPS watch often reads the course long, so aim for a few seconds a mile of margin. The third is never practising goal pace; intermediate and advanced marathon plans here end the long run with a race-pace segment.
How does 3:30 compare with 3:00 and 4:00?
A 3:00 marathon is 6:52 per mile (4:16 per km) and a 4:00 marathon is 9:09 per mile (5:41 per km), so 3:30 sits between them at 8:01. See the sub 3 hour and sub 4 hour pages for their splits. A 1:45:00 half marathon is the same 8:01 pace over half the distance.
How this tool works and where the numbers come from
Pace is the finish time divided by the distance (42.195 km, or 26.2188 miles). Training paces and matching race times use the Daniels and Gilbert (1979) oxygen-cost equations with RunPacePlan’s own zone definitions; the matching times are estimates of equal fitness, not predictions.

Frequently asked questions
What pace do I need to run a 3:30 marathon?
You need 8:01 per mile or 4:59 per km on average. Finishing under 3:30:00 means being slightly faster than that across the whole distance, so check your elapsed time at each marker against the split table.
Is 3:30 a good marathon time?
It is well ahead of the average. RunRepeat’s State of US Marathons 2025 report puts the 2024 US average at 4:34, about an hour slower than 3:30. See the average marathon time page for the figures by age and gender.
What is the halfway split for a 3:30 marathon?
At an even pace the halfway point (21.1 km) comes at 1:45:00. The 30 km mark is at 2:29:18 and mile 26 at 3:28:15.
Can I print the splits or a pace band?
Yes. Print splits prints the split table, and Make a pace band for this time opens the pace band generator with the same goal time.
Does the tool use miles or km?
Either. The Units switch changes every pace and distance on the page, and your choice is remembered in this browser.
Is this medical or coaching advice?
No. The paces are calculated from a goal time. Build up gradually and ask a doctor before starting hard training if you have a health condition.
