The Bear 100 is a 36 hour, 100 mile endurance run that begins in Logan, Utah and ends at Fish Haven, Idaho. Nearly 300 runners participate in this rugged and remote event. Amateur radio operators provide aid station and communications support for runners and crew.
Aid Station operators get into assigned positions, set up and ready to operate about an hour before runners arrive to Station.
Radio operators are needed to man all the feed stations and checkpoints along the route. Our role is to make sure that runners make it safely from check point to check point. It is best to have 2 to 4 hams at each checkpoint.
