AIDSPIRIT USA Marathon

The AIDSPIRIT USA Marathon is a fundraising event that supports orphans and vulnerable children in Uganda. The race takes place in Montana, beginning in the foothills of the Little Belt Mountains within the Lewis & Clark National Forest and concluding in historic downtown Harlowton. The event offers four distinct distances:

  • Full Marathon (26.2 miles)
  • Half Marathon (13.1 miles)
  • 10K (6.2 miles)
  • 5K Fun Run (3.1 miles)

The marathon follow a course consisting of approximately 25 miles of well-compacted, calcium chloride-treated gravel. This route features a gentle, extremely gradual downhill gradient with a net decline of over 1000 feet. The final 1.2 miles traverse Chief Joseph Park on Boomer Trail, ending with a significant uphill section known as Graves Hill. The half marathon and 10K distances also utilize this downhill profile and the same final segment through the park and up the hill.

Aid stations are placed roughly every three miles for the full marathon, with carbohydrate gels provided at specific points for both marathon and half marathon participants. The event has no official course time limit and welcomes both runners and walkers.

The start and finish area at Gally's Brewing Company serves as the hub for celebrations, including music, food, and refreshments. Participants in the longer distances are entered into a random drawing for a vacation flight. The 5K Fun Run stays within the streets of Harlowton, starting and finishing at the brewery.
