How Many Miles Should I Run a Week?

  •  

Figuring out your weekly mileage can be a challenge for any runner, whether you’re brand new or a seasoned marathoner. It depends on your current ability level, the amount of time you have to set aside for running, and your personal goals. Determine how many miles you should run on a weekly basis by following these general guidelines. 

Pro tip: Some runners like to count minutes of running versus miles, but it’s a good idea to invest in a device (like an Apple Watch or Fitbit) that can track your miles.

As you get faster, you’ll run farther in less time, so you want to make sure you’re tracking your weekly mileage accurately! Alternatively, you can also pre-measure distances with your car or a marked trail. 

1. Determine Your Current Fitness Level

If you’re a newbie who doesn’t have much experience with the sport, you’ll want to start slow. You might not be able to run for more than a few minutes at a time, and that’s ok.

Start out with a quick warm up and figure out how many minutes you can run at a comfortable pace. Run that many minutes at the same pace four to five times, with a one to two-minute break in between. 

If you start out running 20 miles per week and you’re feeling good, it’s tempting to add on more, but this can increase your risk of injury. As a rule of thumb, only increase your running mileage by about 10% per week to keep your legs feeling fresh and muscles healthy. 

Pro-tip: Especially if you’re just starting out, don’t forget to account for rest days. You can take a day off from exercise completely–it’s okay!  Or, you can infuse your training plan with cross-training. Consider activities such as cardo elliptical running, strength training, yoga, swimming, or pilates to give your legs a break from the impact on the road or trail. 

2. Consider Your Goals

Every runner has different reasons and goals for their running, which impacts how many miles you should run in any given week. Let’s say weight loss is your goal–you’ll want to work your way up to long-distance runs at a slower pace. If you’re planning to run a 5k, you’ll run a lower number of miles. However, those miles will contain lots of faster-paced runs like tempo runs, interval training, and hill repeats. 

If you’re following a training program for a half-marathon or your first marathon, you’ll build up your mileage incrementally each week. You’ll reach a fairly high mileage with a mix of high-intensity runs, long runs, and easy days to get you ready to cross the finish line with confidence.

Finally, there is no shortage of training programs out there to guide you along the way and prevent overtraining. Check out TRE’s training plans here

3. Listen to Your Body

Don’t be a slave to your training plan. Let’s say you have a 50-mile week planned out and you’re determined to get every mile in. But, on Wednesday, you encounter a stabbing pain throughout your run in your left ankle. It’s tempting for a lot of runners to try to push through the pain, hoping it will go away with time. 

However, in this case, your body is trying to tell you that something is wrong. If you keep pushing, you can end up making the injury worse and risk not being ready for an upcoming race.

Cut your run short, ice the injury and try again the next day. If it doesn’t get better, visit your doctor for diagnosis and advice and supplement with cross-training until you can hit the road again. 

Pro-tip: When you’re coming back from an injury, you can’t hop right back into where you were in your training plan. Take your mileage down by about 10-15 percent and ease your way back into it, depending on how long you were injured. Again, listen to your body! 

5. Days Per Week of Running

Just like everything else, the number of days you run every week varies for each runner. I’ve met many runners that like to run seven days a week and they do just fine with that–but they always incorporate an easy run every week. Most runners who run daily also have an “off-season” where they take a week or two off running to let their body rest. 

However, you can follow a training plan that has you running between three and six days with great results. For example, you might start out by running 15 miles three days a week, then 20 miles four days a week, and up to 30 or more miles five days a week depending on how your body responds. Play around with your schedule to see what works best for you. 

6. Not all Miles are Made the Same

Every type of training run is made out of different types for miles. For example, a race is 100% effort–a 5k race pace is going to deplete you more than a 10k easy run. A six-mile tempo run at 80% effort is going to take more energy than a nine-mile jog. 

The point here is that developing a custom training plan involves a lot more than simply how many miles you are logging. To perform your best, you need to infuse your running schedule with all different types of miles that train your aerobic and anaerobic threshold, work different muscles, and strengthen your endurance in various ways.


Plus, a variety of workouts keeps you from getting bored and brings something new to look forward to each day!
