The Idaho Falls Marathon is an annual road race organized by the Idaho Falls Marathon Foundation, Inc., a 501(c)(3) nonprofit.

The course is described as flat and fast and carries USATF certification. Organizers provide standard race services on event day, including aid stations, medical support, timing chips, and bib numbers. Course routes include city streets and scenic views and are supported by announcers, music, and on-course spectators. A post-race party is part of the event program.

Additional event information includes race maps, official results, and resources for runners such as training programs, travel and lodging details, and options to run for charity.
