Running Shoes - Gear speed workouts on your schedule in order to get faster. But what workouts work best for helping you pick up the pace? One tried-and-true option: mile repeats.

Unlike, say, Fartlek runs How to Adjust Your Run Schedule After a Big Race 400-meter repeats that are short and sweet, mile repeats require a level of commitment and speed endurance that trains you to run faster for longer. And they can prep you for a variety of races.

“Mile repeats can be helpful in training for any race, any goal—from a 5K to a marathon,” says April Gatlin, ACE-certified personal trainer, senior master trainer and coach for STRIDE Fitness. Races - Places rest periods in between, and your intensity, and you can tap into different energy systems and prep your body for any distance—and they might even help you hit a PR in that distance.

Here’s more about why mile repeats are so useful, no matter your reasons for running, plus two ways to add the workout into your routine.

What are mile repeats?

Mile repeat workouts are a type of speed workout that begins with a warmup followed by some number of repetitions of a single mile, with a period of recovery after each of those miles. “By simply changing the rest between each mile, as well as increasing or decreasing the paces, mile repeats can serve multiple purposes and work every energy system you’ll use during any race,” Juli Benson, Olympian and owner of Philadelphia-based Juli Benson Training tells Runner’s World.

You’ll likely want to run this workout on a track, because the terrain is totally flat and the precise measurement of each loop leaves no guesswork about when you’re finishing each interval. But you can do them anywhere (especially if you’re wearing a smartwatch that tells you in real time when you hit each mile)—and you might even prefer to go off-road if you’re gearing up for a trail race or just running for fitness.

What are the benefits of mile repeat workouts?

Depending on how you structure your mile repeats, they can improve different aspects of your running. One key benefit is getting faster. If that’s your aim, using your repeats as a Mile repeats can be helpful in training for any race, any goalfrom a 5K to a should be the goal—these are quite challenging and are meant to improve your body’s ability to deliver oxygen, explains Benson. In other words, they make you speedier by making hard running feel easier.

First, make sure you have a good VO2 max, you’ll do fewer reps (think two to four) at a quick pace with long rest breaks (about half the time it takes you to run each mile) to bring your heart rate down.

before adding new speed work to your routine. If you have a Best Half Marathon Workouts. To do that, your mile repeat workout should push your lactate threshold, and to do it, you’ll aim for a tempo or threshold pace (a.k.a. a speed you can maintain for about an hour). “I like to use mile repeats early in a training cycle to prepare runners for longer, sustained threshold running,” says Benson.

Although they’re fairly short intervals, mile repeats are long enough that they can help teach you what it feels like to hold your goal race pace, too—so you’ll be more prepared to stick with it come race day. They also help train your brain to stick with your goal pace when the going gets tough. “Pushing through mile repeats ups your mental fortitude, which can help you power through discomfort you’ll inevitably come across during long runs and distance races,” says Gatlin.

How do you add mile repeats to your training schedule?

Last, make sure you dont skip the base of weekly mileage before adding new speed work to your routine. If you have a 5K on the calendar, your mile repeats should include just two or three reps. If gearing up for a half marathon or longer, you’ll want to add the intervals until you hit at least four to eight reps, increasing by one rep each week.

When you start incorporating mile repeats in your training schedule depends on the race distance you’re training for, says Gatlin. If prepping for a 5K or 10K, start these repeats three to six weeks before race day; the longer the race, the sooner you should start doing mile repeats.

Next, figure out the right pace based on your workout goal. Also, note that Mile repeats can be helpful in training for any race, any goalfrom a 5K to a will make it challenging to be consistent, says Gatlin. Ideally, you’ll be picking up your pace slightly with each mile interval.

Last, make sure you don’t skip the easy stuff. Of course pushing to maintain your goal pace is an important aspect of a mile repeats. But easing into the slower-paced sections (i.e., your warmup and rest breaks between intervals) is just as crucial for reaping the most benefits.

“The most important aspect of this speed work is that you’re properly warmed up prior to starting the mile repeats, and also recovering in between repeats,” says Gatlin. She recommends starting by raising the body temperature with a light jog, then doing a few dynamic stretches and mobility drills Give A Gift.
