The Big Sky Marathon is a road and trail marathon event that began in 2015 near Ennis, Montana, designed to meet the demand for a back-to-back marathon challenge in Montana, often drawing participants immediately after the Madison Marathon held the previous day. The event was created to appeal to running enthusiasts who seek extreme challenges and the opportunity to complete two marathons in a single weekend, a concept especially popular among members of running groups like the Marathon Maniacs.
