The Dark - Bellevue

Bellevue, Canada • 1-3 Nov 2025

The Dark is a unique ultramarathon held inside the Bellevue Underground Mine in Alberta, Canada. Participants run loops of a 500-meter mine shaft with a gentle 1% grade and about 4 meters width, allowing comfortable running space. The race offers 6, 12, and 24-hour time categories, where runners complete as many laps as possible within their chosen duration.

The mine maintains a consistent temperature of 0° to 2°C year-round, providing stable conditions. Limited to 100 solo runners, the event features a warming station with food at the mine entrance and supports minimal support crew presence. Proceeds partially benefit the historic mine.
