After the close of every league season at the local hockey rink, they hold an Iron Man Tournament.
I always feel like I need to qualify this one to my friends who run. This is not like an Iron Man Triathalon where you run/bike/swim 140+ miles (despite the fact that no zombies are chasing you). Nor is it an I-must-train-for-ten-years-to-do-this-and-not-die-in-the-process kind of deal.
It's also not an I'm-a-super-genius-with-personality-issues-and-I-built-my-own-robot-super-suit kind of deal, though that would be cool too.
