A method of compiling performance metrics for racing competitors by analyzing videos of the competitors' prior races, includes determining: (a) the GPS coordinates of race track landmarks that appear in the videos, (b) within each of the videos' images, the position and orientation of a part for each of the competitors, (c) for each of the videos' images, the camera's extrinsic and intrinsic parameters, (d) the path of each of the competitors from the race's starting line to its finish line, (e) for each of the videos' images, the GPS coordinates of the part for each of the competitors, and (f) using the camera's frame rate, the performance metrics for each of the racing competitors.
