Tires, gears, and costumes are getting final touches for the 25th anniversary of the annual Kluane Chilkat International Bike Relay on Saturday.

The 148.1-mile, eight-leg race runs from Haines Junction in Yukon to the Parade Grounds at Fort Seward in Haines. Approximately 1,220 riders on teams of eight, four, two and one, are expected to participate this year. They’re supported by more than 200 volunteers, some of whom are already at work preparing welcome packets.
