Measure running form improvements
Why Power? Measure running form improvements. Want to improve your finish times? You have two choices: 1) Work on your fitness – so you can run the distance maintaining a higher effort than before; 2) Work on your form – so you can run faster for the same effort, run at the same speed for less effort, or both. If you work on your form, how do you know if your form has improved – that you’re running faster for the same effort? Running Effectiveness (RE).
