Strength Training for Marathon Runners (Expert Tips + Moves)

Strength training for the marathon should balance out your marathon training program, says Mary Johnson, founder of Lift. Run. Perform. As your run training gets more intense, your lifting should get less intense. The strength training for marathon program should include heavy weights and lower reps, lighter weights with higher reps, isometric holds, eccentric moves, and plyometric jumps. Read on to learn what strength moves are best for the marathon and how to time your strength training.

Earlier this spring, I hit a wall. I was strength training for the marathon and felt really fatigued. I had been lifting after my track sessions, but I just felt so tired.

Strength training for a marathon is important and needs to be periodized.

It made sense. My running volume and intensity had really increased, yet I was still trying to lift the same volume and intensity as I was doing in the base phase. It just seemed like too much—and my body wasn’t having enough time to recover.

So, I listened to my body and my better judgment and scaled back on my strength training for the marathon. I had a little bit of guilt around this (I can be very Type A when it comes to running goals) but after talking with Mary Johnson, founder of Lift. Run. Perform., I knew it was the right call. Mary is a strength coach who specializes in strength training for marathon runners.

Strength Training for Marathon Runners—Yes or No?

Study after study shows evidence that strength training is beneficial for runners. It can help runners have more endurance, power, and prevent injury. However, lifting for the marathon should be periodized to fit your run training. Lifting and running should fit together like puzzle pieces, not compete.

But if you’re like me (and I would say, most runners), you don’t have a clue as to how to make marathon training and weight training complement each other. Both can be so taxing on the body, after all.

Mary shares her expert tips on strength training for marathon runners. (Also be sure to check out my Strength Training Guide for Runners which Mary also weighed in on—pun intended).

Yes, runners should lift weights. There are many benefits for runners who lift weights. In fact, Mary said that she recently had a group of 20 runners who prioritized a strength program in their marathon training, and all smashed their marathon PRs.

Some benefits of weightlifting for runners include:

What are the different types of muscles?

There are three types of muscle fiber including, slow twitch, fast twitch, and a group that can essentially be both. It’s important to understand our physiology so we know how and why to train these muscle fiber types.

Muscle fiber types:

  • Type 1 also known as slow-twitch muscles. These muscles contract slowly and use oxygen and glucose to produce energy (ATP). Their contractions don’t use a lot of power, so they take longer to fatigue.
  • Type 2A also known as fast-twitch muscles. These muscles have fast, powerful contractions that use oxygen but can switch to just using glucose, and so can fatigue faster. Most runners tend to predominantly have Type 2A.
  • Type 2B are SUPER fast twitch muscles. These muscle fibers use glucose for their super-fast, powerful contractions, and thus, fatigue quicker than the other muscle fiber types.

People are born with either more fast twitch or slow twitch muscles.

Those good at sprints, but tire easily on runs, have more fast twitch muscle fibers. Runners who excel at long distance events likely have more slow twitch muscles.

Do runners have fast twitch or slow twitch muscles?

In general, long-distance runners have more slow twitch muscles. Sprinters have more fast twitch runners.

Easy running uses more slow twitch muscle fibers but as speed increases, more fast twitch muscle fibers are recruited.

Unless you are only doing sprints or only doing easy running (which I don’t recommend for anyone wanting to progress their running performance), you need to train to strengthen both your slow twitch and fast twitch muscle fibers in both your running and strength training.

How? Variety is the spice of life and the secret to PRs.

  • Your marathon training program should include easy, moderate, and hard running.
  • Your strength training for marathon program should include heavy weights and lower reps, lighter weights with higher reps, isometric holds, eccentric moves, and plyometric jumps, for example.

We can’t change our genetics, but research suggests we can wake-up existing muscle fiber types to help out more.

Is lifting for the marathon different than lifting for shorter distances?

Unless you are lifting for pure sprints, then strength training for marathon runners is not much different than lifting for shorter distances including the mile, 5k, 10k, and half marathon. The main difference is in the periodization of the lifting.

For example, those running a marathon will taper from strength training in the weeks leading up to the race. Runners of shorter distances do not need to taper strength training as much leading up to their race. Generally speaking, the longer the race, the longer the taper of weightlifting.

All runners of all distances should include hypertrophy, power, strength, and endurance lifting. Those training for shorter distances that require more speed may incorporate more power moves such as plyometrics or high weight and low reps.

Lifting for the Marathon: A Strength Periodization Overview

Like running, every BODY is different, so the needs of one person strength training for a marathon may be different than another.

Below is a general overview of what weightlifting periodization for a marathon may look like to complement your running. Please note:

  • The timescales are general. Some people may spend more or less time in each marathon training phase.
  • Also, note that runners should be focusing on all types of strength training throughout the year. There is just an emphasis on some more than others throughout the marathon training cycle.
  • Finally, again, this all depends on the person. For example, someone who has predominantly fast twitch muscle fibers will not see the same results from plyometrics as someone with mostly slow twitch muscle fibers.

Marathon Strength Training Phase 1 (Aerobic Base)

Weeks 1-4 (or 8+ weeks depending on runner’s background and goals)

Share these strength training tips for marathon runners.

Run training aim: During this training phase, marathoners are running mostly easy miles to build their base level of fitness. The focus during marathon base phase is building volume.

Strength training aim: Therefore, during the marathon base phase, runners will home in on building muscular strength. At this point in the training cycle, they do not need to worry about delayed onset muscle soreness (aka DOMS) impacting running workouts so it’s a great time to up the intensity in the weight room (or your house!).

Mary suggests runners who just finished a big goal race, take their training break, and then begin their hypertrophy phase (where microscopic tears from contraction allow our muscles to grow and get stronger) when they are running less.

This way they are building stress when the running demand is low, and they their bodies will have adapted to the new training stimulus by the time running intensity increases.

What it looks like: 3-4 days of lifting a week and 3-5 days of running a week

  • Main focus is on lifting with rep schemes of 8, 12, and 15 reps (at what max percentage)?
  • Do some days of heavier lifts of 3-5 rep schemes. (at what max percentage)?
  • Perform strength training exercises that use both legs. (why both in base?)
  • Also, sprinkle in plyometrics including A skips, B skips, pogo hops, jump squats, skater hops, and box jumps.
  • Never neglect your core!

Marathon Strength Training Phase 2 (Aerobic Strength)

Weeks 5-9

Run training aim: During this phase of the marathon cycle, runners will begin to introduce faster running in the form of fartleks, progression runs, tempos, and steady states.

Strength training aim: As running intensity increases, runners can drop lifting to two strength days per week. They can lift heavy one day and lighter the other. It is best to lift after your running workout to concentrate stress and optimize rest.

What it looks like: 2 days of lifting a week, 4-7 days of running a week with 1-3 speed workout days

  • Lift heavy with 3-5 rep schemes one day and lighter with 8-12 rep schemes on the other day.
  • Begin performing single leg exercises. (why?)
  • Continue to sprinkle in plyometrics and include core.

Marathon Strength Training Phase 3 (Peak)

Weeks 10-13

Run training aim: During the peak phase of training, runners will be doing more intense running workouts with VO2 max speed work, interval, and marathon pace workouts. Intensity and volume are both high during this training phase.

Strength training aim: Because the demands of running are high during the peak phase of the marathon cycle, strength training’s focus shifts to one of maintenance. Runners can lift weights on day a week and do mobility another day. If you are more advanced and can handle the training load, you can continue to lift twice a week on run workout day.

What it looks like: 1 day of weightlifting a week, 1 day of mobility, yoga, Pilates, or barre, 4-7 days of running a week with 1-3 speed workout days

  • Lift heavy with 3-5 rep schemes one day or 8-12 rep schemes with lighter weights, and some plyometrics.
  • If you are more advanced, you can continue to lift two times a week but do one less set, less reps, or incorporate isometric exercises where you hold the weight (using a lower weight) with less reps.
  • Do mobility, yoga, Pilates, or barre on another day.

Marathon Strength Training Phase 4 (Taper)

Weeks 14-16

Run training aim: In the last 2-3 weeks before a marathon, marathon runners will begin tapering for the marathon. This means they will be running less to allow for their bodies to recover and be ready for race day.

Strength training aim: While runners will be running less during the marathon taper phase, this is not the time to increase strength training before a marathon. Runners should be lifting less weights in the weeks leading up to race day to allow for optimal recovery.

Lifting weights and running both create microtears in muscles. When the muscles heal, they build back stronger. However, we do not want to be breaking down during this phase. That has already been done. So, the aim for both running and lifting are to rebuild.

“At this point, runners want to keep themselves glued together and lifting can add injury at some point,” shares Mary.

progressively less.

For most runners, in the few weeks leading up to the marathon, they should stop lifting and instead replace strength:

  • Mobility
  • Yoga
  • Foam Rolling
  • Core and upper body work
  • Physical therapy exercises with bodyweight or bands
