Hagg Mud 50K/25K

The OG Tillamook Forest Race

These Tillamook Forest races are tough, and we aren't joking about that. But an opportunity to run this classic race is back and you don't want to miss it.The 50K course stays on the Wilson River trail the entire time, from one end to the other, and then back to the finish line at Smith Homestead. It doesn't climb Elk and Kings mountains, but don't let that fool you into thinking it is easy. The 25K DOES ascend both Elk and Kings and you'll be using your hands for help as you scramble up rocky and rugged trail. The descents are no joke either and your quads won't thank you for the final one off of Kings mountain. But those views and this experience is all worth it. And new for this year, an 11-mile, point-to-point route on the Wilson River trail. Starting with the 25Kers at Elk Creek and going west to the Smith Homestead. A perfect option for those who don't want the exposure of the 25K or the length of the 50K. This is NOT your typical trail race. No matter the distance you choose, you will have an amazing Fall day in the forest with friends.
