|b This study presents new method used to evaluate the variation of the drag coefficient with the runner's relative velocity. Approximated shape of the runner's body of seven parts was used. Drag coefficient and projected area of each part was evaluated and used to find the runner's body drag coefficient. The results of this method show that the total projected area of the approximated runner's body was 0.6824 m\\ The ratio of this area to the square of the height of runner (1.85 m) was 0.2. The drag coefficient of the sphere was constant with the relative air velocity. For cylinders, the drag coefficient decreases with the air velocity. The drag coefficient of the runner's body varied from 0.867 to 0.968. The results showed the reduction of the drag coefficient with the relative air velocity.
