Race Information
AIDSPIRIT USA Marathon is a 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. Race is entirely on leg-saving compacted gravel with 1800 feet of net decline. Gravel is super shoe-friendly with a calcium chloride-treated hard pack for the majority of the run.
The AIDSPIRIT USA Marathon race is a fundraiser for AIDSPIRIT USA, a 501 (c)3 non-profit organization. They have 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 they raise goes directly to meet the needs of the children they are helping. www.aidspiritusa.org
