AIDSPIRIT USA Marathon Harlowton, MT   Aug 31, 2025

The AIDSPIRIT USA Marathon starts in the foothills of the Little Belt Mountains and finishes in historic downtown Harlowton. This is a fast course! 25 Miles of well-compacted gravel, with a gentle downhill gradient. Course drops just over 1000 feet, but is extremely gradual! The last 1.2 Miles of the course will be through Chief Joseph Park on Boomer Trail with a grand finally butt-kicker finish up Graves hill. Don’t worry though, your victory brew/refreshments, food, medal and music are all waiting for you at the top!

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.
