"Remember our deal, Wonder Boy. The Zeus Cup belongs to me!" On the outside, twelve-year-old Hector seems like he's got it all. He's strong, fast, and rumoured to be the favourite to win this year's Zeus Cup at the Mt. Olympus Spartan Race, the highest honour in his small Midwestern town. Hector's parents and his five siblings trained to win gold in their twelfth year, but all fell short. Now Hector is their last chance to bring glory to the family, and he's starting to feel the pressure. After a mysterious (and extremely talented) girl named Mae obliterates him at the practice run, Hector is desperate to do whatever it takes to win and make his family proud. Cue a certain god of the Underworld who has a mighty proposition for Hector: Hades will give him godlike strength and speed in exchange for the trophy at the end of the race. Seems like a pretty good trade-off. But as Hector soon discovers, no deal with Hades is as straightforward as it seems, and he's going to have to go the distance or risk going from hero to zero.
