An Outdoor Runner’s Secret Weapon: Keep Running Even When It Rains

If you usually run outdoors, the most important thing about buying a backup treadmill isn’t finding something that completely replaces your outdoor routes. It’s finding a machine that lets you continue the workout you had planned on days when running outside isn’t an option.

That means there are three things to prioritize: whether the speed range covers your usual running pace, whether the incline provides enough training variety, and whether the treadmill is easy to store when the weather is good and you don’t need it.

Rain, colder temperatures, or earlier sunsets shouldn’t automatically mean, “I’m not running today.” A good backup treadmill should let you switch from outdoor to indoor running without having to redesign your entire workout.

1. When Rain Moves Your Run Indoors, the Speed Should Match Your Usual Running Rhythm

For outdoor runners choosing a backup treadmill, the first thing to make sure of is that it doesn’t just support walking—it should also handle the running you actually do.

If you originally planned an easy run but can only do low-speed Walking after moving indoors because of the rain, the workout itself has already changed.

The DeerRun Z10 Pro has a speed range of 0.6–7.5 MPH, covering everything from warm-up walking to everyday jogging and Running. When the weather suddenly changes, you can adjust the speed based on the purpose of that day’s original workout instead of switching indoors and settling for “just walking for a while.”

For outdoor runners, a higher maximum speed isn’t automatically better. What matters more is this:

Can the treadmill cover the speeds you actually run most often?

2. When You Lose the Natural Hills Outdoors, Incline Can Bring Some Training Variety Back

If your usual outdoor route includes bridges, hills, or natural elevation changes, a backup indoor treadmill should ideally let you adjust the incline as well.

The Z10 Pro offers up to 12% Auto Incline. You can adjust it directly during your run without stopping to make manual changes.

If you usually run on flat routes, you can keep the incline low. If your original workout included some elevation changes, you can add different incline levels. And if you want to make the workout more challenging, you don’t have to rely only on running faster.

Indoor running can’t completely replicate a real outdoor route, but being able to adjust both speed and incline at least allows you to preserve some of the variation in your original workout.

A backup treadmill isn’t about copying outdoor running—it’s about keeping your workout from shrinking just because the location changed.

3. When Rain Changes Your Plans, Here’s a Simple 30-Minute Indoor Run

If it suddenly starts raining outside, you don’t need to search for a completely new and complicated indoor workout.

Simply keep the time you originally set aside for running and try this 30-Minute Rainy-Day Run:

These speeds aren’t fixed standards. You can adjust them based on your usual running rhythm. The important thing is to preserve the structure of Warm-Up → Steady Run → Training Variation → Cooldown.

That way, the weather changes and the training location changes, but the workout you planned for the day doesn’t have to be completely thrown out.

4. A Backup Treadmill Doesn’t Need to Stay Out Every Day—On Sunny Days, It Should Give Your Space Back

If you’ll mainly use the treadmill when it’s raining, the weather is bad, or going outside isn’t convenient, storage matters more than keeping the machine permanently set up.

The Z10 Pro measures approximately 51.34"D × 26.77"W × 47.01"H when in use, with a footprint of about 9.55 sq. ft.—roughly the floor space of a small desk.

When folded, it measures approximately 54.41"D × 26.77"W × 5.63"H, with a folded thickness of about 5.63 inches. Combined with its built-in transport wheels, you can fold it flat and move it toward a wall or another storage area once the weather clears and you return to outdoor running.

The ideal backup setup is simple: ready to keep your training going when it rains, but easy to put away when the sun comes back out.

5. If You Mix Outdoor and Indoor Running, Don’t Let Your Training Record Break Apart

Your training location can change, but your weekly training rhythm doesn’t have to.

If you normally run outdoors and switch to the Z10 Pro when it rains, PitPat can continue tracking your indoor workouts. You can also use virtual routes and challenges so that the indoor session doesn’t feel like a completely separate workout.

The real value here isn’t simply having another App. It’s allowing your outdoor runs and backup indoor runs to remain part of the same training habit.

You don’t need to start a completely different exercise routine just because the weather changes.

6. A Rainy-Day Backup for Outdoor Runners: How to Know Whether a Treadmill Fits Your Needs

If you mainly run outdoors but want to keep training when it rains, temperatures drop, or the weather makes outdoor running impractical, the right indoor treadmill can serve as a reliable backup to your outdoor routine.

When choosing one, focus on a few key factors:

For outdoor runners, the point of a backup treadmill isn’t to completely replace outdoor running. It’s to keep your training plan moving when the weather doesn’t cooperate.

Before choosing one, ask yourself three questions:

If your answer to all three is “yes,” then the DeerRun Z10 Pro may be a better fit as your rainy-day backup treadmill.
