No Sleep Till Glacial - 24 Hour Team Mountain Bike Relay 2026

No Sleep Till Glacial is a 24-hour team mountain bike relay held at Glacial Hills Pathway and Natural Area in Bellaire, Michigan. Teams begin at 8:00 a.m. EDT and continue through the day and night until 8:00 a.m. the following morning. The race challenges participants to manage the dark hours as much as to ride quickly in daylight. The event takes place on the trails at Glacial Hills, encouraging riders to maintain their effort as fatigue sets in. The core idea is to discover your response at 2:00 a.m., not solely at 2:00 p.m. This is noted as the first annual relay and is sponsored by Chai.
