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

About This Sport

Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.

The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.

Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.

The half marathon rewards people who show up for the boring training miles.

How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
