Teton Dam Marathon
The Teton Dam Marathon is an annual road-race event held in Rexburg, Idaho, around the anniversary of the Teton Dam collapse. The 2027 edition is scheduled for June 5, 2027, and the event takes place in the vicinity of 35 N 1st East, Rexburg, ID 83440. It is traditionally held on the first Saturday in June.
The event program includes multiple distance options to accommodate a range of participants:
- Marathon
- Half marathon
- 10K
- 5K
- Kids race (12 and under)
- Marathon relay
The race series commemorates the June 5, 1976 breach of the Teton River Dam. That collapse caused about $500 million in damage, resulted in eleven fatalities, and left thousands homeless in Wilford, Sugar City, Rexburg, Salem, Hibbard, Firth, Blackfoot, and Roberts. Organizers and local volunteers reference that history when describing the event.
Participant numbers often exceed a thousand runners. Public reviews and organizer notes report a scenic course, visible volunteer support, well-placed aid stations and portable toilets, and generally high ratings from participants. An aggregate rating of 4.9 from 15 reviews appears on the event page. Visit the organization's website for the most recent information.
