Aid Station: The course will include an aid station at the start/finish/lap area for solo racers with water and snacks.

Drop Bags: A neutral feed zone will be available next to the aid station for racers to leave their own supplies.

Course marking: The course will be marked with pink flags to the rider’s right, as well as orange arrow signage for turns. Be aware of sections of the course where traffic is 2-direction – (ground tape will be used in these locations).

Wildlife Safety: Bears, and moose, may be on any trail in Anchorage. Riding with a noise-making bell is required, and carrying bear spray is recommended. Wildlife always has the right of way.

Other Users: The course is not closed. Please be aware of and courteous to other users on the trails. Announce your intentions to pass and do so in a safe place.

Skill Levels: 

For the 50-mile, 50k, relay, and 25k races, we recommend that riders are at a minimum advanced-intermediate riders. The 15-mile course loop will include directional downhill trails including Jeff’s Whoop Whoop, as well as several technical rooty trails including Brown and Black Bear trails.

For the 10-mile race, we recommend that riders are at a minimum advanced-beginner riders. The 10-mile course features 2 laps on an approximately 5-mile loop on a mix of intermediate-rated single track and ski trails. 

Time cut offs: Out of respect to volunteers and race organizers, time cut offs will be in place for the 50 Mile and 50K Races. Racers who miss the cut off will be notified by the timer when they pass the Finish/Start/Lap area. Racers may not change to a shorter distance race once the race has started.

• 50K Solo and Team: complete first lap within 3 hours (avg pace apx 5MPH)
