To Bone and Back Relay
To Bone and Back Relay is a long established event held in Idaho Falls, Idaho. The main format covers a total of 40 Miles offered as a solo ultra or in multiple relay divisions. The event has been held for 34 years in Southeast Idaho.
The 40 mile course is run entirely on asphalt and is described as very hilly. Relay teams exchange only at designated five mile aid stations. Team formats and rules vary by division:
- 40 Miles - solo or relays for 2, 4, or 8 people
- 5 Miles - solo option
Relay details include flexible leg divisions for the 2 person and 4 person teams, with exchanges required at the five mile stations. Eight person teams normally have each teammate run five miles and may not switch runners within a leg; teams may register with five to seven runners so some teammates cover additional mileage. Specific eight person divisions include women, men, coed, family, and high school categories, each with stated eligibility or gender composition rules. There is also a 40 mile solo ultra distance noted as particularly demanding.
The event takes place at 4941 1st St, Idaho Falls, ID 83401, USA. Visit the organization's website for the most recent information.
