Marathon Goal Times What it takes to run a 4-hour marathon

What pace is a 4-hour marathon?

Tilly Ramsay ran her first marathon in London in April 2026 in 4 hours, 1 minute, and 26 seconds. "So incredibly proud of you and your amazing time," posted her dad, the chef Gordon Ramsay. It is an amazing time, and a lesson in how fine the line is: 86 seconds over 26.2 miles is about 3 seconds a mile.

To break 4 hours, you need to average 9:09 per mile, or 5:41 per kilometer. Halfway comes at 2:00:00. Here's where an even-paced 4-hour marathon puts you along the way.

4:00:00 divided by 26.2 miles is 9:09.2 per mile; divided by 42.195 km, 5:41.3 per kilometer.

One wrinkle: your watch will probably say you ran more than 26.2. Courses are measured along the shortest possible route, nobody runs that line perfectly, and when one running site asked readers for their race-day GPS, every one read at least 26.5 miles. At 26.5, 4 hours means 9:03 a mile on the watch, so aim for 9:00 to 9:05.

And the 4-hour line pulls on people. Economists who studied more than 9 million marathon finishes counted 92,970 runners in the minute just before 4:00 and 71,682 in the minute just after. The average finish was 4:27. Break 4 and you're well ahead of average, with plenty of company in that last minute.

How many miles a week do you need for a sub-4 marathon?

Pete Pfitzinger ran the marathon at two Olympics, then co-wrote the book Advanced Marathoning. Asked about the biggest mistake those runners make, he named it: "Overdoing it on the mileage, increasing too quickly." His reason: "the body is very bad at adapting quickly to more than it's used to."

So the answer has two parts: how high you peak, and where you start. Most sub-4 plans peak at about 40 to 55 miles a week. Buena Vida's peak near 40 on 3 days a week, 45 to 47 on 4, and 50 to 54 on 5. Higdon's Intermediate 1 reaches about 44, Runner's World's Break 4:00 about 48, and Pfitzinger's 18/55 about 55. Long runs top out at 18 to 22 miles.

More miles generally help. When researchers at Memorial Sloan Kettering surveyed 2,303 recreational runners, those training 50 miles a week ran their marathons about 25 to 32 minutes faster than those training 30. That's an association, not proof.

Where you start matters just as much. A plan should begin near what you already run, and lots of injuries start with one run that goes well past your longest of the past month. So most sub-4 plans ask you to arrive running 25 to 35 miles a week, then add slowly. The long run carries the most weight: marathoners who run longer long runs tend to finish faster. "The long run would still be number one," Pfitzinger said.

More miles means more food. Going from 30 to 45 miles a week adds roughly 1,500 calories to a 150-pound runner's week, and eating enough to cover your training is what lets those miles build you up.

What a sub-4 training week looks like

Shalane Flanagan, who won the New York City Marathon in 2017, treated the kitchen as part of her training. She co-wrote a cookbook, Run Fast. Eat Slow., with Elyse Kopecky, and of eating that way while training for Boston, she told FloTrack: "Specifically, in prep for Boston, I feel strong."

Here's the biggest week of Buena Vida's 18-week sub-4 plan (4 days): week 14, about 47 miles, with the food that fits each day.

Threshold is a hard but steady effort you could hold for about an hour. Strides are short, relaxed pickups.

Most of the miles are easy, because easy running is the base the hard days stand on. There's one hard midweek session. And there are 2 short strength sessions, because strength work prevents more injuries than stretching does, and about 2 a week is enough.

Why threshold instead of more goal pace? For a 4-hour runner, marathon pace sits well below threshold, so they're different kinds of training, and either is a reasonable choice. Plans split here: Pfitzinger puts long stretches of goal pace into his long runs, Runner's World's Break 4:00 has none before race day, and Buena Vida's use threshold for the hard days and goal pace as rehearsal.

Now the food column. Saturday's 18 miles burns roughly 2,000 calories for a 150-pound runner, and Sunday almost nothing extra. So the food rises with the runs and settles back to normal meals on rest days (normal, not less). Eat the same every day and the long run comes up short.

The key workout: a long run with miles at goal pace

The most famous sub-4 workout happens on a track. Bart Yasso, then Runner's World's race services manager, told the magazine's Amby Burfoot about a workout he'd been doing for about 15 years. "I'm trying to build up to ten 800s in the same time as my marathon goal time," he said. For a 4-hour goal, that's 800 meters in 4 minutes, 10 times. Runner's World's Break 4:00 plan uses 8 of them.

Yasso 800s are a fun check, but no set of 800s can tell you whether you'll hold 9:09 for 26.2 miles. The workout that comes closest is a long run with goal pace in the middle. Pfitzinger ranks marathon-pace runs right after the long run, as "simulating what you're going to do," and warns they're "tough on the body," so good plans use them sparingly.

In Buena Vida's 18-week plan, it grows from 14 miles with 3 at goal pace in week 9 to 18 with 5 in week 14 (9 easy, 5 at about 9:08, 4 easy). Pfitzinger's 18/55 goes further, with up to 14 goal-pace miles inside a 17- to 18-miler. Either way, you learn what 9:09 feels like on tired legs, so on race day it feels familiar.

It's also where you practice race fueling: "you would want to take in nutrition similar to what you want to then do in the marathon," Pfitzinger said.

How much to eat while training for a sub-4

Before the 2022 Boston Marathon, researchers at Boston Children's Hospital surveyed 1,030 runners about their eating and training. More than 2 in 5 women and nearly 1 in 5 men showed signs of eating too little for their training, and those runners finished slower than runners of similar age, build, and training. "The important takeaway of this study is that fueled is faster," said Nicole Farnsworth, a clinical nutrition specialist on the study team.

Weeks of 40 to 55 miles take a lot of food, and eating enough for your training is what turns those miles into fitness. Match it to the day, like the sample week: more on long-run and threshold days, with extra carbs, and normal meals on rest and strength days. Don't try to save calories on training days.

After the long run and the threshold or goal-pace days, eat a real meal with plenty of carbs to refill your legs and some protein to repair them (adding protein to carbs can help muscles refill faster). Spread protein through the day, too, about 20 to 40 grams a meal. Runners need more of both than people who don't train.

Eating too little shows up in your training first: heavy legs that never feel fresh, paces that stall or feel harder, getting sick more often, and sleeping badly. Those are among the signs the International Olympic Committee's experts list, and over time low energy weakens bone and raises the risk of stress injuries. So if your goal-pace miles start to feel like a race, look at what you're eating before you change your goal.

How you’ll know you’re on track

Most race-time calculators use a formula built on world-record times. When the Memorial Sloan Kettering team checked it against their 2,303 recreational runners, it held up to the half marathon, but for the marathon it was at least 10 minutes too fast for half of them. A 1:55 half "predicts" a 4-hour marathon. Plenty of 1:55 runners finish after 4:10.

So trust your own record over a calculator. Run a tune-up half 4 to 6 weeks out: around 1:50 says sub-4 is realistic, and tune-up races may help as pacing practice. Watch your goal-pace miles: if the 5 at 9:09 inside your 18-miler feel controlled, the pace fits, and if they feel like a race, consider 4:10. And around week 8, compare an easy run with one from week 1. Same pace, lower heart rate? That's your fitness showing up, and an Apple Watch is accurate enough to show it.

The record catches trouble, too: a long run that jumped too far, a week where you ran more and ate less, shoes quietly piling up miles. Those are easy to miss when your runs, food, and plan live in three places.

Race day

Will Ferrell ran the 2003 Boston Marathon in 3 hours, 56 minutes, and 12 seconds. Afterward he described Boston's most famous climb: "Heartbreak Hill felt like a lovely summer day ... and then you get hit over the head with a hammer."

The hammer usually lands late, and most of it is set up early. In the economists' split data, runners reached halfway in 2:11:55 on average and finished in 4:42:07, a second half about 18 minutes slower than the first. Benjamin Rapoport, who studied hitting the wall as an MD/PhD student at Harvard and MIT, put the cure simply: "Once you figure out your target pace, you have to stay at it." Go out at 9:09 (or about 9:03 on the watch), not 8:45 because the early miles feel easy.

Before then, your plan gets lighter on purpose, because a taper of up to 3 weeks, cutting volume while keeping some speed, helps you race better.

And if you're on 4-hour pace with a mile to go, you may find a gear you didn't know you had. In the same study, about 25 percent of runners sped up over the last 2.2 kilometers, but among runners right on target for a round number, about 35 percent did. Patient early miles leave you something for that.

Nine minutes and nine seconds, a little over 26 times. You can train for that.
