Race Information

​Set in the shadow of Tahoma (aka Mt. Rainier), this classic race offers amazing views of Washington's tallest mountain. The 50M race features 10,200ft of gain, ridge tops, northwest forest, and mostly single track trail. For decades runners, including many of the best, have come here to push themselves and run in this spectacular place! Compared to previous years, some adjustments to the course have been made that reduce the out and back portion on the first loop and take runners on some new trails with new views of Rainier, right below Snoquera Falls and down the steep Deep Creek Trail. These changes make an already scenic course even better!  

There's a 50K option, which follows the 50M course for the first 29.5 miles of the race, then heads back to the finish at Buck Creek Recreation Area. This scenic and challenging course has many of the same highlights as the longer course, but with only 6,300ft of gain.

The 25K course follows the 50M & 50K courses for the first 10.8 miles (other than a slightly different start) and then takes a big shortcut. After the Palisades section, the 25K will skip the Corral Pass section and drop down the Ranger Creek Trail to return to the start/finish area.
