Background
The event is timed each year to coincide with the anniversary of the Teton River Dam failure on June 5, 1976. That collapse caused an estimated $500 million in damage, resulted in eleven fatalities, and left thousands homeless in Wilford, Sugar City, Rexburg, Salem, Hibbard, Firth, Blackfoot, and Roberts. The race description cites volunteer aid and community response following the 1976 flood as part of the event's historical context. Visit the organization's website for the most recent information.
