Marathon Pace Chart: Finish Times from 3:00 to 6:00 (Pace per Mile & Km)

A marathon has one honest question at its heart: what pace do I need to hold to finish in my goal time? The answer is simple arithmetic. A 4-hour marathon needs 9:09 per mile (5:41 per km) — every single mile, 26.2 times in a row. A 3-hour marathon needs 6:52 per mile (4:16/km). A 5-hour marathon comes out to 11:27 per mile (7:07/km). That is the entire mystery of marathon pacing: your finish time divided by the distance gives you the per-mile price of admission, and this marathon pace chart prices every goal from 3:00 to 6:00.

The math is exact — a marathon is 26.2188 miles (42.195 km), and these are the paces that add up to each finish time. Find your row in the chart, then read on for what those paces actually demand, how to split your race, and how to pick a goal you can trust.

Bookmark this page for training season. Runners tend to think in round finish times — 3:30, 4:00, 4:30 — and then guess the per-mile cost on the fly. With your row memorized (9:09 for 4:00, 8:01 for 3:30, 10:18 for 4:30), every workout gets a number attached to it: your marathon-pace miles, your easy pace relative to it, and the exact speed you need on the treadmill.

The Marathon Pace Chart

Every pace below is computed from the official marathon distance: finish time in seconds divided by 26.2188 miles for the per-mile pace, and by 42.195 for the per-kilometer pace, rounded to the nearest second. These are the paces you would need on a perfectly even split — the rhythm every training plan is built around.

Finish Time	Pace per Mile	Pace per Km
3:00	6:52	4:16
3:15	7:26	4:37
3:30	8:01	4:59
3:45	8:35	5:20
4:00	9:09	5:41
4:15	9:44	6:03
4:30	10:18	6:24
4:45	10:52	6:45
5:00	11:27	7:07
5:30	12:35	7:49
6:00	13:44	8:32

Notice how the gaps widen toward the slower rows. Moving the goal from 3:00 to 3:30 buys you 69 seconds of pace per mile; moving it from 5:00 to 5:30 buys you another 68. Every extra minute in your finish-time goal makes each mile noticeably cheaper — which is why picking the right goal row matters far more than squeezing a few seconds out of any single workout.

If your watch and your races run in kilometers, work straight from the per-km column and ignore the per-mile numbers entirely — the rows are the same goals either way. A 4:00 marathon is 5:41 per kilometer, and that is the number to program into your watch alerts for pacing, fueling reminders and course checkpoints.

The Famous Goals Up Close

Sub-3 (6:52 per mile). This is the line between very fast and near-elite. A sub-3 marathoner holds 4:16 per kilometer — roughly 21:20 for every 5K of the race — 8.4 times in a row. That pace is a hard tempo run for most club runners, and sustaining it takes years of consistent mileage, structured workouts and usually a coach or a serious plan, not just talent. If you are within reach, the gains come from the long run, fueling discipline and race-day execution, not from one magic session.

Sub-3:30 (8:01 per mile). The experienced runner’s milestone. Dropping from 4:00 to 3:30 shaves 68 seconds off every mile — a jump that usually comes from a second or third training cycle, not from trying harder on race day. Runners who break 3:30 tend to have two things the 4:00 group is still building: a genuinely easy long run pace and the discipline to run the first half of the race slightly slower than the second. It is also the point where a coach or a well-chosen plan starts paying for itself.

Sub-4 (9:09 per mile). The most chased club in running. Nine-oh-nine is a pace many regular runners can hold for a 10K but must learn to sustain for 26.2 miles — and the gap between the two is where marathon training lives. Most sub-4 plans peak around 40-55 miles a week, with the bulk of it easy running and a weekly session at or near goal pace. The biggest single predictor is simple: can you run 9:09 on tired legs in the last miles of a long run, while taking in fuel? Nail the fueling and the pacing, and the fitness usually follows.

The 4:30-to-5:00 rows deserve respect too. A 10:18-to-11:27 mile is where most first marathons land, and it is the smartest goal for a debut: ambitious enough to demand real training, forgiving enough to survive a rough patch at mile 22 without the day falling apart.

And about Boston qualifying: qualifying times vary by age group and change from year to year, so check the BAA’s own site for your current standard rather than training to a number you saw quoted somewhere last year.

Splits for the Big Goals

A pace only becomes a plan when you can check it mid-race. These splits give you the cumulative clock readings at each checkpoint for the two most popular goals. If you are ahead of the 10-mile split but slower than your target pace, you know exactly how the morning is going — no guesswork on the course.

Checkpoint	4:00 Goal (9:09/mi)	3:30 Goal (8:01/mi)
5 mi	45:46	40:04
10 mi	1:31:32	1:20:08
Half (13.1)	2:00:00	1:45:00
20 mi	3:03:04	2:40:16
Finish	4:00:00	3:30:00

The checkpoint that matters most is the half. Cross halfway at 2:00:00 on a 4:00 goal and you are exactly on the money; arrive at 1:57 and you have three minutes in the bank — but the bank charges brutal interest after mile 20, so spend it carefully. The 20-mile split is the honesty check: reach it in 3:03:04 with fuel still going down smoothly, and you are about to finish strong.

On race morning, reduce your splits to the ones you will actually see. Most runners write three numbers on their hand or arm: the 10K, the half and the 30K mark at 18.6 miles. Your watch shows distance in real time, but the hand-written trio is what you check when your brain goes quiet at mile 22 — and it keeps you from doing math with a tired head.

Even Pace or Negative Split?

For almost everyone, the plan is even effort — roughly the same pace per mile from the first mile to the last, which is what every row in the chart assumes. A true negative split, running the second half a touch faster than the first, is the elite ideal, but it works best for runners experienced enough to know exactly what even effort feels like when the adrenaline is flowing.

What usually breaks a marathon is not the pace plan but the fuel tank. Around mile 20, most runners’ glycogen stores run low — the famous wall — and pace collapses no matter what the chart said. That is a fueling failure, not a pacing failure: taking in roughly 60-90 grams of carbs per hour from gels, chews or sports drink is what lets the plan survive the last 10K. Start the race 5-10 seconds per mile slower than your goal pace for the first couple of miles, let the crowd’s adrenaline pass, then settle into your row.

One exception worth naming: on a hilly course, even effort does not mean even pace. Mile splits will swing up and down with the terrain while your breathing stays level — so on a rolling course, chase the feeling, not the row.

Whatever your strategy, rehearse it before race day. Most plans include marathon-pace miles inside the long run — say, 6-8 miles at your chart pace in the middle of an 18-miler — specifically so the pace feels boring and automatic by the time it counts. A pace you have practiced for weeks is a pace you can hold when the crowds and the nerves are loud.

How to Choose Your Goal Time

Do not pick a goal from the chart by hope. The classic rough guide: take a recent half marathon, double it and add 10-20 minutes. A 1:52 half becomes roughly a 4:00 marathon (double is 3:44, plus a little under 20 minutes). The faster you are, the less you add; the slower, the more. It is a starting estimate, not a contract — the course profile, the weather and how long ago that half was all move the number.

If your most recent race was a 10K instead, our race pace calculator predicts your marathon finish time from that pace — a recent 10K is a genuinely useful predictor for most runners. Either way, pick the goal your training supports, not the one your imagination prefers. Then train the actual pace: our treadmill pace chart converts every marathon pace into the belt speed you need for indoor sessions (9:09 per mile, for example, is about 6.6 mph).

And if you have never run a marathon, make the goal finishing strong. A 4:30-to-5:00 target gets you to the line with a smile on most debut training plans — and sets up the second marathon, which is where the real time-chasing begins.

Finally, re-test before you commit. A goal picked 16 weeks out should survive contact with your training: if your marathon-pace workouts feel controlled and your long runs end strong, the goal stands. If every goal-pace mile is a battle by week 8, move one row down the chart. The chart does not judge — it just shows you the price, and a price you can pay is always better than a dream you cannot.
