Many runners perceive the treadmill as boring. If you do not change the pace and incline the entire run, the treadmill will feel mind-numbingly boring. Think of outdoor runs: you have variations in pace and incline, even slight changes on a flat easy run. These six treadmill workouts offer fun treadmill options for everything from easy runs to interval workouts.
All these treadmill workouts reinforce aerobic development. Base-building phases typically include controlled intervals, hills, and lots of easy running – the same as these treadmill workouts. (Read more here for what a base building phase includes.) Most likely, you are in a base training phase during winter, which is when you are probably also spending the most time on the treadmil.
(These quick guides to training paces and the different types of running workouts are helpful for understanding these treadmill workouts!).
Treadmill Easy Run
When you run outside, you likely encounter some variation in terrain. Even a slight 1% incline or decline, you change your pace and mechanics. You can mimic these changes on your treadmill easy run by varying the elevation and pace throughout.
The simplest approach is to vary the incline every few minutes. You can be structured or unstructured with the incline changes. The exact incline you use will depend on what you typically do outdoors. Most road runners will find that 0% to 6% inclines feel the most like their outdoor training. Trail runners may prefer to mix in steeper inclines up to 12% and include treadmill hiking, as they would on an easy trail run.
Any pace variations should be small. To keep the run truly easy, keep the pace within your easy pace or heart rate range. You do not want to turn this into a speed workout!
Sample treadmill easy run: 5 min at 0%, 3 min at 2%, 1 min at 4%, and repeat through the remainder of the run. As you change the incline, slightly vary the pace to maintain a similar rate of perceived exertion (RPE).
Treadmill Interval Run
Interval training can make treadmill running more fun. However, high-intensity speedwork can make you feel like you are about to fly off the back of the machine. A safer alternative are controlled intervals. These workouts offer the fun of a treadmill interval run while also fostering aerobic development. Overtraining risk is lower, especially during a base-building or early-season phase.
Controlled intervals foster high-end aerobic development and intermediary muscle fiber recruitment. These are not gut-busting intervals; these are hard but not too hard. In terms of intensity, they should feel like an effort you could sustain if you were racing around 30-40 minutes. Depending upon your ability, that ranges from 5K to 10K effort. These type of intervals are a staple in training plans for athletes such as the Ingrebringsten brothers, Eliud Kipchoge, and other greats. (This podcast provides an excellent breakdown of Norwegian training principles and how they can be applied to athletes of various abilities.)
Theoretically, they may come with lower risk of injury on the treadmill. Many runners run with slightly altered biomechanics on the treadmill. A 2020 meta-analysis in Sports Medicine found that treadmill running, while overall similar to outdoor running, did cause slight differences such as the angle of knee flexion upon footstrike. Treadmill running can place more stress on the Achilles tendon and calf muscles. Given that high-intensity running also increases stress on the musculoskeletal system, more controlled intervals may be a safer alternative then very fast repeats if kinematics are already slightly altered.
Sample treadmill interval workout: 5-8 x 3 minutes at 30-40 minute race effort/1.5 minute recovery jog (include a 10-20 min warm-up and 10-20 minute cool down with easy running)
Treadmill Hill Workout
The treadmill makes hill workouts accessible no matter where you live. Hill workouts offer numerous benefits to runners such as improved mechanical output and running economy. On the treadmill, you can control the exact incline for the goal of your hill workout.
Caveat: these workouts place a high strain on the calf, Achilles, and plantar, so they should be used with caution if you are prone to injuries on the lower leg.
You can do hard hill repeats on the treadmill. Another versatile option is moderate-intensity hill climbs. These can be beneficial if you find you struggle with uphill running in long races or if you are a trail runner.
Sample treadmill hill workout: After a 10-15 minute warm-up, repeat 3 minutes at 5-8%, 3 minutes at 0%, at an easy to moderate effort for the remainder of the run. If you are using a five-zone model, this would be training in zone 2 to zone 3 efforts. Your pace will stay relatively the same, but effort will be higher on the uphill segments. (Set the incline based on your ability. If you are new to hills, start on the lower end; if you are a trail runner, aim for the higher end.)
Treadmill Progression Run
The treadmill allows you to manipulate pace with the touch of a button – so take advantage of it! Even if you struggle with pacing, a treadmill allows you to carefully and incrementally increase your pace on a progression run. A progression run begins at an easy pace; then you gradually run faster throughout. A progression run can finish at any intensity. For long-distance runners, it is most beneficial to keep progression runs aerobic in nature, which means finishing at a moderate intensity (in the range of half marathon to 50K pace).
Sample treadmill progression run: Start the first 10 minutes at 10-15 seconds per mile slower than your usual easy run pace. Then, increase the pace by 0.1 mph (or roughly 10-20 sec/mile) every 5-10 minutes (depending on the duration of your run – a longer run means longer intervals). Continue to increase until you are running at a moderate effort, or roughly 60-90 seconds per mile faster than you started.
Treadmill Threshold Run
A continuous threshold run on the treadmill can make time feel like it is slowing to a crawl. However, threshold runs do not have to be continuous to be effective. (Here’s more on the science of threshold runs.) Breaking a tempo run into intervals creates an effective workout, especially during a base-building phase when you want to avoid too strenuous of efforts. A threshold interval run breaks up the effort into 3-8 minute threshold intervals with short (1-2 minute) recovery jogs.
The priority with threshold intervals is to keep a controlled pace. The treadmill allows you to set it to your threshold pace (what you could maintain if you raced for one hour, or a moderately hard effort). You are less likely to push too fast in this workout. As a result, you have a productive workout that quickly passes time on the treadmill.
Sample treadmill threshold workout: 4-6 x 5 minute at hour-race effort (10K-15K pace), with a 1-2-min recovery jog in between. (Include a 10-20 minute warm-up and cooldown with easy running.) You will notice a range in the recovery jog. If you are in a base phase, use a 2-min jog; if a race is closer, use a 1-min recovery jog.
These are just a sample of treadmill workouts! The options for treadmill workouts are as various as outdoor running workouts.

I definitely think the key is to keep changing things up when it comes to treadmill running! I usually like to play around with pace and incline. I have no idea when I will run on a treadmill again (probably next Christmas!) but I will have to keep these workouts in mind for when I do!
They’re great workouts for when treadmill running does occur – especially if it is the holidays and you want to get in and out of the gym quickly!
I’m the same way, give me fresh air any day of the week BUT if it comes down to time constraints or the conditions are just plain crazy (hello ice!), then I’ll hit the treadmill. These workouts will come in handy for me during the next few months. Although fingers crossed I don’t have to use them too often! 🙂
Ice is definitely a reason to hit the treadmill! Even if you could run on it, it can throw off form so much. Hopefully you don’t have to be on the treadmill too often this winter!
Wait…did you write that you used to run exclusively on the treadmill???? What? OMG, why? You need to write more about that!! So glad you have now found yourself out on the roads 🙂
Love this round up and hope I can try your workout soon!
I know! It was senior year of college through grad school, when I’d run before sunrise, lived by myself, and relied on the treadmill for safety (especially in grad school). Plus Midwest weather can be really nasty!
I tried your workout this morning – loved it! The hills made the treadmill so much more comfortable both physically and mentally!
As it is 10 deg currently, you better believe my walk will be on the treadmill….
You can do Allie’s workout as a walking workout, I bet! Just get a good podcast and you are ready to go.
Ohhhh boy it’s that time of year again eh?
I don’t have access to one anymore so I’m running outside come rain, sleet, snow or vortex. Whoo hoo.
I did some of the pre programmed hill workouts in the gym treadmill last winter while training for Pittsburgh. My goodness it was hard. Don’t ever let anyone say the mill won’t give you a good enough workout!
Be sure to stay safe in all that winter running! Hill workouts on the treadmill are so hard – and they may just be my favorite way to keep the mill interesting!
I’m always looking for new treadmill workouts so this is perfect! Thanks for sharing 🙂
I hope you enjoy them!
It’s like you knew that our polar vortex has returned! I’m pinning this and will be putting it to use as early as tomorrow…
I hope these workouts get you through many polar vortex runs! And I hope the polar vortex isn’t as bad as in previous years!
interval workouts are the only way to do treadmill workouts!
The variety is needed!
I’m going to try Run Far Girl’s hill workout today because I haven’t done hills in forever; I’ve been on the treadmill most of the time because of our snowy/icy conditions. Thanks for these!
Sarah’s a strong hill runner so you know her workout will be great! I hope you enjoy these workouts!
I need to refresh my treadmill routine. These are awesome!
These will definitely refresh your routine – there’s some great variety here!
Love your fartlek treadmill workout- I will definitely be giving it a try!
I hope you enjoy it when you try it!
These are great! I love the treadmill for intervals on icy, cold days or for short easy runs in the early morning when I can listen to music and zone out. Looking forward to adding some of these in!
The treadmill is so great for fitting in a hard workout when it’s gross outside and too slippery to run fast!
I’m with you — I much prefer running outside. The only time I won’t is: if it’s dark out and it’s potentially icy OR if it’s below 0˚. Because that’s just ridiculous… I may be crazy but I’m not negative temperatures crazy. 😉
Negative temperatures are just crazy! My rules is that when it’s below 0 even for the wind chill, I go inside. 🙂
I am so NOT a ‘miller, but I can (sometimes) handle workouts like these because they incorporate intervals into them…so they don’t really seem like “running” LOL
Steady state running on the treadmill is so hard! It’s a mental challenge but then gait just feels off. The intervals or hills help with using different muscles!
I run on a treadmill 3-4 times a week for an hour at a 10 minute mile. I watch an hour long show just to keep my boredom down
