I’m a Marathon Runner, and This Is My Favorite Walking Pad Workout

As someone who's logged thousands of miles on roads, trails, and tracks preparing for marathons, you might assume my go-to workout always involves running. But here's the truth: Some of my favorite training sessions happen at a walking pace on my walking pad at home. Because as Lifehacker senior health editor Beth Skwarecki has explained before, walking is cardio. Most important for me, walking workouts are cardio without the impact stress that comes with running. This makes them perfect for recovery days when you want to maintain fitness without adding to your overall training load. Especially when I'm pressed for time—or need active recovery that still delivers results—I turn to a high-incline walking pad routine.

Now, when you hear "walking workout," you probably think of the trendy 12-3-30 routine. While its promises are wildly overblown online, I have no problem with this workout. It's both simple and challenging: You set the incline to 12% (the highest you can go on many treadmills), the speed to 3.0 miles per hour (a pretty typical walking speed for most of us on flat ground) and you do it for 30 minutes. Personally, I need a routine with more variety. If all I did was walk the same speed and incline for 30 minutes, I'd lose my mind. It's just not the same as zoning out for 26.2 miles.

What the 12-3-30 gets right is a focus on steep incline. You can speed-walk all you want, but without solid incline, you won't be activating all the same muscle groups used in running. Think glutes, hamstrings, and calves—these are the muscles you need to hit to make it through the later miles of a marathon. Trust me.

My 30-minute high-incline walking pad workout

To do this workout, you need a walking pad that gets up to 12% incline and 4 mph. For me, that's the Merach W50 (which I review here, if you want to learn more). As with any workout, you can adjust the numbers to suit your fitness levels or walking pad specifics. If you do adjust certain speeds or sections, I recommend sticking to the spirit of the workout: intense incline (to keep your muscles engaged) with constant variation (to keep your mind engaged). The variation within this workout is what keeps me consistent over time, where the 12-3-30 had me burnt out by day two.

Warm-up (five minutes)

• Minutes 1-2: Walk at 2.5 mph, moderate incline (6-8%)

• Minutes 3-5: Gradually increase to 3.2 mph, increase incline to 10%

Main set (20 minutes)

This is where the magic happens.

Minutes 6-9: Power walk intervals

• 30 seconds at 4.0 mph, maximum incline

• 90 seconds at 3.5 mph, maximum incline

Repeat this pattern twice.

Minutes 10-13: Steady state

• Maintain 3.8 mph at maximum incline

This should feel comfortably hard—you should be able to speak in short sentences.

Minutes 14-17: Speed ladder

• Minute 14: 3.3 mph, maximum incline

• Minute 15: 3.5 mph, maximum incline

• Minute 16: 3.7 mph, maximum incline

• Minute 17: 4.0 mph, maximum incline (or your maximum sustainable speed)

Minutes 18-25: Pyramid intervals

• 1 minute at 4.0 mph, maximum incline

• 30 seconds recovery at 3.0 mph, reduce incline to 8%

• 2 minutes at 4.0 mph, maximum incline

• 30 seconds recovery at 3.0 mph, reduce incline to 8%

• 3 minutes at 3.8 mph, maximum incline

• 30 seconds recovery at 3.0 mph or slower, reduce incline to 8%

Cool-down (5 minutes)

• Minutes 26-28: Gradually decrease speed to 3.0 mph, reduce incline to 6%

• Minutes 29-30: Easy walk at 2.5 mph, incline at 3%

Progressive overload options

Once this workout feels too easy, you can progress by:

• Increasing the speed during intervals by 0.1-0.2 mph

• Adding one to two minutes to the main set intervals

• Incorporating brief jogging intervals during the speed ladder section, if your walking pad gets fast enough

• Adding light hand weights (one to two pounds) for increased upper body engagement

The bottom line

As runners, we sometimes get caught up in the idea that harder always means faster or farther. A good walking-pad workout reminds me that intensity can come in many forms. The combination of steep inclines and strategic speed work creates a challenging, time-efficient session that beautifully complements my running training. Give it a try the next time you're pressed for time but still want to challenge yourself—with that incline maxed out, your legs will definitely feel it the next day.
