Review the results and adjust your workout as needed.

The calculator will show you the exact time you should spend running and walking, as well as a visual representation of your workout structure.

How Run Walk Intervals Work

Run walk intervals involve alternating between periods of running and walking. The basic principle is to push your body to work at a higher intensity during the running portions while allowing for recovery during the walking portions.

The key to effective run walk intervals is finding the right balance between running and walking. Too much running can lead to fatigue and injury, while too much walking may not provide enough challenge to improve your fitness.

Most experts recommend starting with a 60/40 ratio (60% running, 40% walking) for beginners. As you get more comfortable, you can gradually increase the running percentage.

Benefits of Run Walk Intervals

Run walk intervals offer several benefits for runners of all levels:

Improved endurance: The alternating high and low intensity helps build stamina and increase your ability to sustain longer runs.
Reduced injury risk: The walking portions allow your muscles to recover, reducing the risk of overuse injuries.
Efficient training: You can cover more distance in less time, making it an efficient way to train.
Flexible intensity: You can adjust the running percentage to match your fitness level and goals.

Whether you're a beginner looking to build a foundation or an experienced runner seeking a challenging workout, run walk intervals can be a valuable addition to your training routine.

Example Calculation

Let's say you want to do a 30-minute run walk interval workout with a 70% running percentage:

Example Inputs:

Total workout time: 30 minutes
Running percentage: 70%

The calculator would show:

Example Results:

Run time: 21 minutes
Walk time: 9 minutes
Workout structure: Run for 21 minutes, walk for 9 minutes, repeat for a total of 30 minutes

This means you would alternate between running for 21 minutes and walking for 9 minutes, completing the workout in 30 minutes.
