How to Find Your Half Marathon Pace

Your half marathon pace feels, “comfortably uncomfortable,” says Ben Delaney, director of adult training programs for New York Road Runners. “It’s not super fast, like a mile, 5K, or a 10K, where you’re having to really work into these really uncomfortable type paces and hold them for a certain amount of time,” Delaney says. But it’s not quite as comfortable as marathon pace, which is why it can be tricky to find.

If you’re an experienced runner, you can use familiar paces to help you find your half marathon rhythm. And if you’re a newbie, there are ways to find your half marathon pace without referencing previous times.

If you do know your 10K pace, then add 20 to 30 seconds per mile to your average mile time to find your half marathon pace, Delaney says. If you’ve done a marathon, you can subtract anywhere from 40 to 60 seconds per mile. If you’re a newbie, go for a trial run. Run the number of miles you feel most comfortable with, aiming for a speed that feels comfortably hard, and use that to determine your pace, says Delaney.

Online pace calculators, which can help you calculate paces for any distance ranging from one mile to 26.2 miles based on the time it takes you to run a certain distance, can help you find a more exact pace. Just remember these tools are meant to be used as a guideline, so you may run slower or faster than what the calculator suggests.

“A lot of times those online pace calculators are going to provide you with a pace in an optimal environment to run. Meaning the perfect conditions, on the perfect day, on the flattest course,” says Delaney. In other words, calculators don’t account for environmental factors like weather, for the first time, or planning to smash your PR, weve got the.

If you’re not into running with a watch—or you’re new to figuring out pace calculations—use your rate of perceived exertion (RPE) to figure out your half marathon pace. This is a personal assessment of how challenging an exercise is for you physically and mentally, on a scale of 1 to 10. Your half marathon pace is about a 7 on the RPE scale, says Delaney.

No matter what method you use, remember to listen to your body, and dial it back a bit if you feel like you’re overworking yourself. Throughout your training plan, you’ll be able to fine tune what pace works for you to cover 13.1 miles and the closer you get to race day, the better you can set that pace goal.
