Event Features

A unique feature called "The Nonsense" introduces a new challenge at the top of every hour, which runners must complete during that hour.

The organizer, the Curious Ultrarunner’s Secret Society, aims to build community and inject whimsy into running. The event has a focus on inclusion, offering free entries for BIPOC and LGBTQ+ athletes as an affirmation of belonging. The registration policy accepts each entrant’s declared gender at face value and provides a process for non-binary athletes to specify their pronouns after registration.
