About

The MIDNIGHT Rat Race - UNSANCTIONED is an unofficial, roughly half marathon (13.1 miles / 21.1 km) endurance challenge in Springfield, starting at 11:59 p.m. on October 16, 2026. Listed as the Half-Marathon-ish, it sends runners around an urban course with no markings and no volunteers.

Participants have to rely on their instincts and resourcefulness to get round, and a time limit applies. The event is aimed at experienced runners looking to test their limits; competitors are encouraged to make the most of the night and plan their route carefully for a demanding, one-of-a-kind experience.
