Treadmill Running for Marathon Training

Many people successfully train for marathons on treadmills. Whether for a specific marathon speed workouts or all of their marathon training runs. I prefer to run outside. But running on a treadmill can be more convenient.

Because of the dark winter nights, you may feel safer running on a treadmill indoors while training for a spring marathon. Running a marathon on a treadmill can also be a viable option if you live in an area where it is either extremely hot and humid or extremely cold and icy!

Treadmill training is sometimes the only option for marathon training. There are a few things to consider when using a treadmill for marathon training. I'll share five of my favorite treadmill running tips to help you maximize your marathon training.

If you choose to train on a treadmill for your marathon, there are a few key points to keep in mind:

1. Treadmill Settings for Outdoor Running

Running on a treadmill and running outside are two very different things. For starters, outside running involves “dragging” or wind resistance, whereas, on a treadmill, you are essentially running in place.

Researchers recommend running on a treadmill at a 1% incline to simulate outdoor running to compensate for the lack of wind resistance. However, this 1% figure ignores the biomechanical effects of running on a moving belt.

2. Treadmill Incline for Better Run


Adding a slight incline to your treadmill run has benefits beyond wind resistance. When you run outside, you must use your glutes and hamstrings to propel yourself forward with each stride. The constantly moving treadmill belt does that work for you.

When training for a marathon on a treadmill, I recommend an incline of at least 3% for “flat” runs. The treadmill incline forces the runner to work harder through their glutes and hamstrings.

This prepares their legs for running outside on marathon day!

The addition of an incline to your treadmill running workouts may help to prevent knee pain. Running uphill makes it much more difficult to overstride.

You'll have to slow down your pace a little to accommodate the incline when adding an extra incline to your treadmill running workouts.

I'd recommend adjusting the treadmill's speed based on effort rather than rigidly following a set speed.

3. Treadmill Workouts-Marathon Training


Running on a treadmill during marathon training allows you to be very specific about your speed workouts. Normally, the treadmill will show you all the data.

Treadmills can even be programmed to deliver specific workouts. Just run and keep up!

Hill workouts improve leg speed and strength. A favorite of runners who struggle to push themselves to run fast during flat interval sessions.

4. Treadmill Marathon Training

The reality of training for a marathon on a treadmill is that you must complete your long runs, just like you would outside.

Your longest marathon training run will be determined by your experience and goals. For example, the longest long run in my beginner marathon training plan is 18 miles.

Running outside keeps your brain busy with a variety of sights and sounds. This keeps the miles moving quickly. Treadmill boredom can set in quickly.

On the treadmill, I use audiobooks and podcasts to distract my mind. Experiment with different methods – music may work for you.

Drinks and nutrition are readily available on a treadmill for long marathon training runs.

If you ran outside, you'd have to carry your long-run nutrition and drinks, but on the treadmill, you can keep them nearby.

5. Practice Your Target Marathon Pace

This is a key session in any marathon training plan. These are the sessions where we improve our aerobic efficiency and endurance for the 26.2-mile run. It's not just about the miles but also about the pace.

Many runners run their long runs too fast. Most of your long runs should be slower than your marathon pace.

Determining your target marathon pace becomes increasingly important as race day approaches.

The benefit of running on a treadmill is that you can precisely control the speed to meet your goals.

There are several running technique coaching points to consider when running on a treadmill, as some runners run differently on a treadmill than they do outside.

Consider these key points:

Include Room for Normal Arm Swing


Avoid running too close to the main treadmill console. Runners who sit too far forward on the treadmill get too close to the console.

This limits their ability to swing their arms as naturally as they would if they were running outdoors. Running can result in excessive shoulder tightness. Not what you want after three hours on the treadmill!

Here's a tip for runners who have tight shoulders: Relaxed Shoulder Running

Use the clip-on safety cord as an extra precaution if you find yourself running too far forward on the treadmill to avoid drifting back and falling off the end.

Heads up and Look Ahead

Many new treadmill runners are tempted to look down at their feet. Your head is heavy, and as soon as you look down, your posture changes.

When running on a treadmill, pay attention to your posture and head position. Try to run tall and forward-looking.

It's fine to glance down to check your position on the treadmill, but remember to look up again!

Be careful if you're running in a gym with TV monitors in front of the cardio area. Running with your eyes to the left or right is a recipe for disaster!

If you want to watch TV while you run, choose a treadmill with the monitor directly in front of you!

See your Footfall


Running on a treadmill allows you to hear how your feet land on the machine's deck. Listen as you run to hear if you're pounding the treadmill or running lightly.

Aim to run gently with short, quick strides that result from a fast enough running cadence for the given pace.

Make shorter, faster strides if you hear loud foot contact with each stride.

A treadmill can train for a marathon, now you know. As a result of the advice in this article, I am confident that you can effectively train on the treadmill.
