10 Treadmill Workouts That Help Improve Your Speed

When cold, dark, rainy, or icy conditions make it tough to get outside, the obvious option is to hit the treadmill. The good news: Doing speed workouts on the treadmill makes the time seem to fly by faster than Noah Lyles on the track.

So, we asked five running coaches to recommend their favorite speed workouts for the treadmill. Keep in mind, the paces in the workouts below are merely suggestions. While it’s great to stick to them if you can, there’s no harm in slowing down if you feel you need to.

Some workouts are based on your rate of perceived exertion, some are based on your race pace (take a look at our pace charts if you’re not sure what your goal 5K pace is vs. a marathon pace), and some are based on how the efforts feel. For instance, an easy warmup should feel like you can hold a conversation without issue. A fast interval might feel like your 5K pace where you’re working hard but not going all out. And a sprint should feel like the final kick of a race when you’re giving it everything you’ve got.
