Idaho Triple Crown- Marathon 2026

The Portneuf Health Pocatello Marathon, part of the Idaho Triple Crown series, takes place in Pocatello, Idaho, under the nickname “Running the Gap.” This early September road marathon includes pace teams, online registration, published course maps, lodging and travel details, and a pasta dinner during race weekend. The race information directs runners to course maps for route details, with the “Running the Gap” name serving as the clearest course indicator. The Pocatello Sports Committee organizes the event, which has now exceeded twenty-four editions. Participants receive complimentary course and finish-line photos, processed using bib-tagging software, with Gate City Sports providing assistance for any missed bibs. An online store is also available for runners to personalize their medals.
