Splits for a 4:00:00 marathon

Even pacing holds one pace from start to finish. The negative plan starts 2% slower than average and finishes 2% quicker, so the first half takes 2:01:12 and the second 1:58:48. The 2% is this site's illustrative preset, not a coaching prescription. Both plans reach 4:00:00 to the second.

Whole-second paces that break 4:00:00

Watches and pace charts show whole seconds, and the one that looks right can land just over the goal. The highlighted row is the slowest pace per mile that finishes under 4:00:00. Here the exact average rounded to the nearest second, 9:09, is also the safe pace.

If your watch reads long

Courses are measured along the shortest route a runner could take, so most runners cover a little more and their GPS watch shows more distance than the course. The finish clock counts only the course. This is the watch pace that still gets you under 4:00:00 on the clock:

Printable pace band for 4:00:00

The band below lists even splits every mile. Print this page with Ctrl+P (Cmd+P on a Mac) and only the band prints: a 40 × 240 mm strip with a 50 mm ruler to check the scale. For negative splits, run/walk or a different split spacing, open the pace band generator with 4:00:00 filled in.

Why so many runners finish at 3:59

Four hours is the most crowded goal in the sport. In 9,789,093 marathon finishing times from 1970 to 2013, Allen and colleagues (2017) counted 29.5% more finishers in the minute before 4:00 than in the minute after it, and more runners bunched at four hours (48,230) than at any other round number. The authors put this down partly to pacing and planning and partly to extra effort over the final 2.195 km. The practical lesson: the final 2.195 km decides many 4-hour attempts, so know your mile-26 target. At even pace it is 3:58:00, two minutes before the finish time, not 4:00:00.

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 the minimum, not the target. 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 the runners. Adding weekly mileage improved the researchers' predictions, and running 50 rather than 30 miles a week was associated with marathon times 25:32 faster for men and 31:41 faster for women. A 1:55:07 half marathon is therefore a sign that 4:00 is possible, not a guarantee. If your weekly mileage is low, expect to need a faster half.

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.
• Trusting the watch's distance. If your watch reads 1% long at the finish, it has to show 9:03 per mile for you to break 4:00 on the clock. Use the mile markers and the band's elapsed times.
• Banking time early. The negative plan above is 1:12 behind even pace at halfway (2:01:12) and still finishes on time; going out at 8:50 per mile puts you ahead of both plans, a lead you then have to protect over the last 10 km.
• Using a chart that stops at mile 26. The last 0.2188 mile takes about two minutes, so a mile-26 target of 4:00:00 is two minutes slow.

Plan a different goal

The marathon pace chart lists every goal from the fastest times to walking pace, and the split calculator with 4:00:00 filled in adjusts the splits to any finish time.
