Alice Wins the Derby

Alice, Julius, and one other character are in a combined auto/horse race. Julius gets off to a bad start when his car takes off, without him, in the wrong direction; it takes him a while to get it straightened out. Alice and the bad guy battle a bit for the lead, which Alice takes; they pass a detour, which the bad guy changes the sign for. Julius, taking the bad road, eventually drives up a cliff and, after a mighty struggle at the top, makes it, in third place, to the changeover. (imdb)
