Mission 18HR Adventure Race
Mission 18HR is an 18 hour adventure race scheduled for May 2, 2026 at Deam Lake State Recreation Area. The event sends teams and approved solo entrants through multi-discipline navigation using map and compass with UTM plotting on a 1:25,000 scale.
Participants travel by foot, bicycle, and canoe, and face special challenges and technical navigation segments. The event includes cycling on and off road, trekking, paddling, and potential ropes or climbing elements for the full length event. Teams must remain together within 100 feet at all times. Field limits are enforced at 50 teams per race length and online entry closes April 25 or when divisions sell out.
Entry fees vary by division and date; fees cover two meals for 18 hour entries, race maps, post-race meal, event insurance, professional management, and awards. Team divisions include two and three person Coed, Female, and Male categories. Solo applicants for the 18 hour division must submit a race resume documenting relevant experience; solo entrants are expected to carry a phone for emergencies.
Scoring is checkpoint based: teams earn points for punched checkpoints and incur penalties for missed or skipped items. Maps and checkpoint information are released in segments during the race. A detailed mandatory gear list and technology restrictions are enforced, including prohibitions on GPS navigation features and requirements for personal and shared safety and cycling equipment.
