Why so many runners finish at 3:59

More marathoners bunch at four hours than at any other round number. Allen and colleagues (2017) went through 9,789,093 finishing times from 1970 to 2013 and counted 48,230 runners bunched at 4:00, with 29.5% more finishers in the minute before it than in the minute after. They put this down partly to pacing and planning and partly to extra effort over the last 2.195 km.

So learn your mile-26 time before you start. At even pace it's 3:58:00, two minutes before the finish, and a chart that stops at mile 26 won't show you that.

What 3:59 and 4:01 mean per mile

Over 26.2188 miles, each minute on the finish clock is 2.3 seconds a mile (1.4 seconds a km), and five minutes is 11.4 seconds a mile. Finishing under 3:59:00 needs 9:06 a mile. Under 4:01:00 allows 9:11. The table shows the slowest whole-second pace that finishes under each target:

For the tiers either side, see 3:30 marathon pace and 5-hour marathon pace.

Splits for a 4:00:00 marathon

The even plan holds 9:09 or 9:10 for every mile. The negative plan starts 2% slower and finishes 2% quicker: you pass halfway at 2:01:12, 72 seconds behind even pace, and run the second half in 1:58:48. If you've never run one, negative splits explained shows how the shape works. Both plans reach 4:00:00 to the second.

Two rows catch people out. Mile 13 on the even plan is 1:59:00, because the halfway mat comes 0.1094 mile later, so don't read mile 13 as your halfway split. And the negative plan's first mile is 9:20, so a slow opening mile on that plan means it's working.

To plan a different finish time, open the split calculator with 4:00:00 filled in. For the same goal on a treadmill, the treadmill pace chart gives the speed to set.

Which pace to hold on the watch

The highlighted row is the slowest whole-second pace that still breaks 4:00:00. For this goal it's 9:09, the same as the exact average rounded. Each extra second a mile adds 26 seconds at the finish, which is how 9:10 turns 3:59:54 into 4:00:20.

Courses are measured along the shortest route a runner could take, so a GPS watch usually shows more distance than the course (USATF). If yours reads 1% long, it has to show 9:03 a mile for you to break four hours on the clock. The pace converter switches any of these paces between miles and kilometres.

If you plan walk breaks at 4:00, the run/walk calculator works out the running pace they cost: with 4 minutes running and 1 minute walking, the race is exactly 48 cycles, 3:12:00 of running and 0:48:00 of walking.

Fuel for four hours

A four-hour marathon runs well past 2.5 hours. That's the line Burke and colleagues (2011) draw in their review of carbohydrate for training and competition: beyond it, they say, intakes of up to 90 g an hour may help.

If you take a gel every 30 minutes, that's 7 gels and 154 g, about 39 g an hour. At even 4:00 pace the 30-minute marks fall near miles 3.3, 6.6, 9.8, 13.1, 16.4, 19.7 and 22.9, so you can write them on the band. That's clock arithmetic, so try the schedule on your long runs first to see how much your stomach takes.

Four hours and Boston

4:00:00 is the Boston qualifying standard for women and non-binary athletes aged 55 to 59 in the 2027 and 2028 races. Meeting it only lets you apply. For 2027 the B.A.A. accepted qualifiers who were 5:17 or more under their standard, so this group needed 3:54:43: that's 8:57 a mile or 5:33 a km. The Boston qualifying times page lists every age group with its pace.

What a 4-hour marathon usually takes

Riegel's endurance formula, in the form most calculators use (a known time multiplied by the distance ratio to the power 1.06), links a 4:00:00 marathon to these shorter race times:

Treat those as minimums. In a survey of 2,303 recreational runners, Vickers and Vertosick (2016) found the formula well calibrated up to the half marathon but at least 10 minutes too optimistic in the marathon for half of them. Weekly mileage improved their predictions: running 50 rather than 30 miles a week went with marathon times 25:32 faster for men and 31:41 faster for women. A 1:55:07 half says 4:00 is within reach, and no more than that. If your weekly mileage is low, you'll want a faster half first.

Common 4-hour marathon mistakes

• Pacing at 9:10. It looks like 9:09 rounded, but 26.2188 miles at 9:10 is 4:00:20.
• Pacing off the watch's distance. A watch that reads 1% long has to show 9:03 a mile for a sub-4 on the clock, so use the mile markers and the band's elapsed times.
• Banking time early. Going out at 8:50 a mile puts you ahead of both plans, and that lead then has to last through the final 10 km. The negative plan is 1:12 behind even pace at halfway and still finishes on time.
• Aiming for 4:00:00 at mile 26. The last 0.2188 mile takes about two minutes, so your mile-26 time should read 3:58:00.

How the numbers are worked out

14,400 seconds over 26.2188 miles is 549.23 seconds a mile, which reads 9:09; held for the whole race, 9:09 gives 14,394 seconds, or 3:59:54. Each checkpoint is the exact elapsed time rounded to the nearest second, so no split drifts more than half a second and the last row is 4:00:00.
