* DESIGN FILE *  Running speed trials: * P.1 * P.2 * ***TSHIRTS*** 
PROCEDURE: Make at least three runs at different constant pedal rpms (about 20, 40, and 60 rpm), each repeated in opposite direction. (Six passes over course, minimum). [4] In each pass, record start and end of timed run when range marks line up at each end. Difference is elapsed time over course. During pass count number of pedalpushes with one foot, from start to finish of course. This number, divided by elapsed time over course (in minutes) is pedal rpm. Calculate speed over course as follows: Plot results on graph paper as follows: 
miles per hour 
best straight line through 0,0 and most points pedal rpm
