Most of us enjoy running outside, rightly so, and it should be the cornerstone of your training. But, in these uncertain times indoor running may offer a great alternative.

Treadmills allow you to control factors such as pace and incline, as well as removing variables like wind, people and surface changes. You can test and retest with greater accuracy, it’s light and safe, getting ready can be quicker, and mirrors offer the chance to see yourself run so you can build a more efficient stride.

The benefits of running indoors on a treadmill 

The best treadmill deals

  

You can do any session on a treadmill, but this session is designed to help build or maintain speed. While long, steady runs are the default for many during the winter months, my feeling is that polarised training that builds speed while maintaining aerobic fitness is far more beneficial. All reps are under 45secs so that they don’t tip over into threshold work – that can come later in the season, if there’s a season!

Coach’s top 3 tips for the session

Keep well hydrated

Running indoors can induce heavy sweat loss, so make sure you drink around 200mls every 20mins and that you include electrolytes. Two to three pinches of salt in 500mls should suffice.

Wear calf guards

Treadmills generally present a softer surface than pavement, but the change under-foot is a stress that your calves might not be used to, so wear calf guards during your first few sessions.

Crank up the tunes

Listening to music is a really good way to distract you from the effort, which can linger in the forefront of you mind when indoors. Choose music that motivates and energises.
