AIDSPIRIT USA Marathon is a running race on September 6, 2026 in Harlowton, MT, with entry fees from $35 to $140.
From the Organizer
Speedy race from the Little Belt mountains in Lewis & Clark National Forest to Historic Harlowton MT. Start this race with epic views of the Crazy Mountains and finish with a complimentary hand-crafted pint from local Gally's Brewing Company. Race is entirely on leg-saving compacted gravel with 1800 feet of net decline. Gravel is super shoe friendly with calcium chloride treated hard pack for the majority of the run.
This race is a fundraiser for AIDSPIRIT USA, a 501 (c)3 non-profit organization that has been providing orphaned, abandoned, or abused children in the Kayunga District of Uganda with a safe home, food, clothing, medicine, and most importantly, an education since 2009. Every penny we raise goes directly to meet the needs of the children we are helping. www.aidspiritusa.org
