What is it?
When you run not all power is dedicated to moving forward. Form Power is that number, in Watts, that is not being used to move forward.
Why does it matter?
The result of a lower Form Power is that a larger percentage of your total power is being used towards efficient forward motion. Said another way, two runners that are identical in every way except for differing Form Power values (say 70 watts and 75 watts) may race a mile in 6:00 and 6:30 respectively.
