Nobody Loves the Treadmill: How to Make Winter Miles Bearable

Winter is coming to the northern hemisphere, and for a lot of runners that means outdoor miles go from uncomfortable to unsafe. Ice, darkness, and wind chill push a lot of us inside, which means one thing: the treadmill.

Most runners don't love it. You can run for an hour and literally go nowhere. Workouts feel twice as hard, the minutes crawl, and the whole thing can feel like a punishment for living somewhere with real winters.

I'll be honest though: I don't hate the treadmill. I use mine occasionally year round, not just in winter. It's easier on my joints and feet than pavement, and my family puts somewhere between 800 and 1,000 miles a year on it. The difference between treadmill miles you dread and treadmill miles you can actually enjoy comes down to setup, the right machine, and a few small habits.

Here's everything I've learned.

Make It Watchable: The TV Trick

The single biggest thing that makes treadmill running bearable for me is TV. I mounted a TV on the wall near my treadmill so I can watch shows and movies while I run. On a good day, I genuinely forget I'm on a treadmill. A good episode makes an easy hour disappear.

I know that's not an option for everyone. If you're running at a gym, a tablet works almost as well. Most gym treadmills have a ledge or reading rack that will hold one, and plenty of home treadmills have one too.

One tip: save your best shows for your hardest sessions. If you're only allowed to watch the next episode of something great during a tempo run, you'll start looking forward to tempo runs.

Get a Fan. Seriously.

Outdoors, the air moving past you keeps you cool. On a treadmill, there's no airflow, so you heat up faster and your heart rate drifts higher at the same pace. That's a big reason treadmill runs feel harder than they should.

We run a high volume fan pointed right at the treadmill, and I'd call it a must. The little fan built into most treadmill consoles isn't enough. A real floor fan makes a bigger difference to how a run feels than almost anything else on this list.

Try the 1% Incline

You'll hear this one a lot, and there's real research behind it. A study by Jones and Doust (1996) found that setting the treadmill to a 1% grade best matched the energy cost of running outdoors, mainly because there's no wind resistance indoors.¹ It's a small change, but if you want your treadmill miles to feel closer to your road miles, start there.

Treadmill Pace vs. Watch Pace

Your treadmill and your watch will probably disagree on your pace, and that's normal. Indoors, your watch can't use GPS, so it estimates pace from your arm swing or cadence, which is a guess. Treadmills can also drift out of calibration over time, which mine has.

My advice: trust the treadmill for pacing during the run initially, since that's what's actually moving under your feet. If your watch numbers matter to you, look for a "calibrate" or "save distance" option after a treadmill run, which lets you correct the distance to match the treadmill. Many Garmin and Coros watches support this. If you are certain your treadmill pacing is out of calibration, you may have to go by feel and heartrate.

Treadmill Workouts Don't Have to Be Miserable

Easy miles on a treadmill are one thing. Workouts are another. Staring at a console while you grind through intervals is a different kind of hard. A few things help:

• Break it into small blocks. Six 4-minute intervals feel more manageable than "24 minutes of hard running." Focus on one rep at a time.
• Try progression runs. Bump the speed a little every mile or every few minutes. Having something to change keeps your brain engaged.
• Use the incline. Hill workouts are where treadmills shine. You get perfectly controlled grade and pace, which you can't do on a real hill, and no painful downhill on the way back.

What to Look for in a Treadmill

If you're buying one for your home, this is where most people go wrong. You need a treadmill that's powerful enough for where you want to be, not just where you are now. An underpowered treadmill might feel fine when you're a beginner, but in a couple of years it won't go fast enough for your workouts, and the motor will struggle under you.

Here's what actually matters for runners:

• Continuous horsepower (CHP), not peak horsepower. Peak HP is a marketing number. CHP is what the motor can sustain for an entire run. For running, look for at least 3.0 CHP.
• Top speed of 12 mph. That's a 5:00 mile. You may never use it, but a treadmill that tops out at 10 mph can feel limiting for faster intervals.
• A 60-inch belt length. 55 inches is fine for walking, but runners need the extra length so their stride doesn't feel cramped. Width matters too. A 22-inch belt gives you room to relax instead of worrying about stepping off the edge.
• Incline range. Look for at least 10%. More is better if you like hill workouts.
• Warranty. A long motor and frame warranty is one of the best signals of build quality. Manufacturers don't offer lifetime coverage on parts they expect to fail.

Try Before You Buy

A treadmill is a big investment, and I think the most important step is trying them in person. Specs only tell you so much. How the belt feels under your feet and how loud the motor is at speed matter just as much.

I bought mine from a regional gym equipment dealer. We tried three brands: Spirit, Precor, and a cheaper brand. I really liked both the Precor and the Spirit, but the Precor cost about twice as much, and we couldn't justify spending that.

We went with the Spirit XT685.

We've had it for three years and have been very happy with it. The run quality is great, the belt is smooth, and the motor is plenty powerful without being loud. On paper, it checks every box from the list above: a 22" x 60" belt, a top speed of 12 mph, up to 15% incline, and a non-folding frame built for frequent running.

Some higher-end treadmills come with a built-in TV or a giant touchscreen. In my opinion, that's just something else to break. You're better off buying a cheap TV and mounting it on the wall like I did. If the TV dies, you replace a $200 TV, not a $2,000 console.

Measure Everything First

Before you buy anything, take detailed measurements of the treadmill and your space. You need a couple of feet of clearance behind the treadmill, a little in front, and a foot or so on each side. The space behind matters most for safety. If you ever slip off the back, you want floor, not a wall.

Don't forget the ceiling. This catches a lot of people with basement treadmills. Add your height, the treadmill's deck height, and a few inches for the bounce in your stride. Then remember the front of the deck rises when you use incline. I'm 6'5", and at our old house the basement ceiling was 7'6". It was cutting it close, and we measured carefully before we bought. Our current basement has 9-foot ceilings, which is a lot more comfortable.

Check your outlet, too. Many running treadmills call for a dedicated circuit, so check the manual before you plug it in. You don't want to trip a breaker in the middle of a tempo run.

Put a Mat Under It

I put a rubber mat under our treadmill. It was originally on carpet. Now it sits on rubber flooring over concrete, and I still use the treadmill mat on top of the rubber flooring. It helps with cushioning, keeps the machine stable, and protects the floor from sweat. Our mat is a generic brand, but this Amazon Basics treadmill mat is essentially the same thing for about $30.

You Will Sweat Everywhere

With no airflow, treadmill sweat goes everywhere, especially on hard workout days. It gets on the console, the handrails, the frame, and the floor. Sweat is corrosive over time, so wiping the machine down after runs helps it last. We use Wipex gym wipes. They're tough enough to actually clean the machine without leaving it sticky.

Maintenance: Easier Than You Think

We've had our treadmill for three years. After two years, we had a technician come out to service it. He said everything looked great, serviced and cleaned it, and told us that every two years was plenty based on our usage, which is about 800 to 1,000 miles a year, mostly easy cruising with some harder workouts mixed in.

Check your manual for your specific model's schedule, but for most home runners, regular wipe-downs plus a professional service every couple of years is all it takes.

Safety Basics

Use the safety clip. It feels unnecessary right up until you trip, and then it stops the belt before you get thrown into the wall behind you. If you have kids or pets, keep them away from a running treadmill, and unplug or lock it when it's not in use.

Don't Go Cheap

Last thing, and it's the most important: don't go cheap. A cheap treadmill will turn into an expensive coat rack. If the belt slips and the motor bogs down, you won't want to run on it. It'll slowly collect laundry and junk, and it'll make you mad every time you look at it.

Spend the money once on a machine you'll actually use. Over 800 to 1,000 miles a year, a good treadmill pays for itself fast.

FAQ

Is treadmill running easier than running outside? It can be slightly easier at the same pace because there's no wind resistance. Setting the incline to 1% helps close that gap. On the other hand, the lack of airflow can make treadmill runs feel harder because you heat up faster, which is why a fan matters so much.

Is the treadmill better for your joints? Many runners find it easier on their joints and feet than pavement, because the belt and deck have some give. That's a big reason I use mine year round.

How much horsepower does a treadmill need for running? For regular running, look for at least 3.0 continuous horsepower (CHP). Ignore peak horsepower, which is a marketing number.

How much room do I need for a treadmill? Plan for a couple of feet behind it, a little in front, and about a foot on each side, plus enough ceiling clearance for your height, the deck height, and the bounce in your stride.
