Event: Half Marathon
The race will start and end at the Old Airport on the west edge of West Yellowstone. There is a ton of parking there and it is easy walking distance from many hotels on the south side of town.

The majority of the race takes place on a dirt road and trail in Gallatin National Forest immediately southwest of West Yellowstone, MT.

The course starts flat but has a major and a minor hill that you need to train for. The best part of the course is that you will be less than a mile from the west park entrance!
