"Along with the Half Marathon we have a 5K on Friday night after the expo.
If you find yourself up for a bigger challenge, consider signing up for one of our double or triple events.
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. You can see a map and elevation on the course link on the website. The best part of the course is that you will be less than a mile from the west park entrance. That is 32 miles from Old Faithful and 24 miles from the Grand Prismatic Spring.
