About
Idaho Falls Marathon is held on July 24, 2027, in Idaho Falls, Idaho. Three distances are offered: the marathon (26.2 mi), the half marathon (13.1 mi) and a 5K (3.1 mi), with aid stations and medical support along the courses. Start times are not listed in our records.
Eastern Idaho sits near 4,700 feet and the high desert cools sharply overnight, so a July marathon there usually starts cold and finishes warm — the widest temperature swing you will meet in a summer race. Dress for the middle of the race rather than the start, and expect the altitude to cost you a couple of minutes over the distance.
