【How-to】How long did i run

Walk at a normal speed from one end of the course to the other, counting your steps as you go. Divide the total number of steps into 100, and you’ll find out the length of one step. For example, if you took 50 steps to go 100 feet, your step length is 2 feet. If it took you 40 steps, figure 2 1/2 feet per step.
