A method for measuring power generated by a person during running includes the use of a pair of sensor insoles, each having force sensors. The method utilizes at least one computer device for performing the following: determining a reference distance ratio for the person； receiving force data from the plurality of force sensors； calculating a distance run based on a product of the reference distance ratio and a total number of impulses received in the force data； determining total force, and time elapsed during which the force data is received from the force sensors； and calculating and reporting power.
