Course Descriptions

Printable overview Course Map with aid stations (PDF)

With three exceptions the courses are common with the relay course that will be run simultaneously. The name Mt. Si Ultra is a little misleading: You run at the base of Mt. Si not up it! The 50K course is 95% trail with about 1,000 feet of elevation gain and loss. The 50K merges at the 19.4 mile location of the 50-mile course. The 50-mile run is 88% on trail with 1,400 feet of elevation gain and loss.

The courses run on the Snoqualmie Valley and Iron Horse Trails, providing views of the Cascade foothills and the Snoqualmie and Tolt Rivers.

The 50-mile course follows city roads and the trail from the town of Snoqualmie northwest to Fall City and to the South edge of Carnation, where runners turn around and run southeast to North Bend.

At the 19.4 mile mark, in the town of Snoqualmie, the 50-milers will be joined by the 50K runners and head to Rattlesnake Lake via the Snoqualmie Valley Trail and then to Twin Falls Trailhead via the John Wayne Trail in Iron Horse State Park. Here they will make a U-turn at an aid station and head back to the finish at Snoqualmie Elementary School.

The trail is old railroad grade. It offers a gentle elevation and is generally wide with some crushed rock, but usually is packed dirt and grass. The steepest climb is from North Bend to Rattlesnake Lake, which is 450 feet over five miles.
