You race by pressing the right and left arrow keys (in that order) as fast as you can until you reach the finish. I didnt make a menu or a "race again" option because I had trouble resetting the positions of the ai ants (due to the fact that they are cloned). Just to let you know before you play, as soon as you press game mode, the race begins, so get your fingers ready! Also, your ant is the maroon one that I believe is the third from the top.
