ABOUT THE SPIRAL
The Spiral is an endurance track race designed to challenge your mind as much as your legs. It’s just you and the track, loop after loop. No changing scenery, no distractions, no finish line.
It’s a raw test of how far you can go in six hours. For some, this will mean pushing the boundaries well beyond an ultra. For others, it’s a chance to reach a new milestone in a crowd-free setting.
You’re free to run, walk, mix it up and take breaks when needed. There’s no pressure to run for the full six hours.
We’ll be there to support you: whether you're chasing a personal best, trying to hit a new distance or just trying to keep sane while circling the track…
