Bear Lake Blunder Run
The Bear 100 Mile Endurance Run is an ultramarathon that traverses the Wasatch and Bear River Ranges west of Bear Lake, from Logan, Utah to Fish Haven, Idaho. With 21,986 ft (6,701 m) of climb and an average elevation of 7,700 ft (2,300 m), it is one of the more difficult ultramarathons. Even so, runners of all skill are attracted to it, largely because of its 36-hour time limit and laid-back attitude (all of the race directors and assistants have participated in the race, and some participate every year). The run is held on the Friday and Saturday before the last full weekend in September. This normally augurs warm fall days and cool nights in spectacular fall color, hence the run's motto "36 Hours of Indian Summer."
