Bar-Ka-Koo Ultra & Relay 2025

The Bar-Ka-Koo Ultra & Relay challenges solo runners or teams of 2-5 to conquer a 55 km course, consisting of five 11 km loops run in alternating directions. The course is 75% technical single-track and 25% Nordic ski trails, with a strict 10-hour cutoff. This is a self-supported race with minimal course markings. Your entry fee includes event-branded swag, and all finishers earn a medal—but only a few will make it to the end.
