S01E41 Adventures in the Forbidden Zone

Hercules finds himself in a fierce rivalry with a new recruit named Theseus, which escalates when Theseus dares Herc to a chariot race. The stakes are high, as the racecourse runs dangerously close to the ominous Forbidden Zone, a place where mortals enter but never return. As the competition heats up, the trio—Herc, Theseus, and Iolaus—realizes they may be the next to fall victim to its dark powers, turning the race into a desperate fight for their lives.
