Registration for the 27th annual Kluane Chilkat International Bike Relay opens at 12:01 a.m. Monday, March 16, and organizers said they expect the 1,200 rider slots “will fill quickly again this year.”

The event is set for June 20, over the 148.1-mile (238-kilometer) course from Haines Junction in the Yukon Territory to Haines.

There are solo-rider and team categories for men, women and mixed teams, with two, four or eight riders per team.

“This international event has filled up in just a few days over the past few years,” the organizers said. “Along with the 1,200-rider cap, there is a limit of 95 teams in the eight-person category.”

Solo riders have until April 10 to register.
