Cascade Super Ultra 50M | 50K

September 26 @ 6:00 am - 5:00 pm PDT

|Recurring Event (See all)

An event every year that begins at 6:00 am on day last of September, repeating until September 27, 2025

The Cascade Super Ultra is the newest addition to the Cascade Super Series. A stunning point to point course running from South Cle Elum to Cedar Falls, the race features one of the fastest 50M trail races you will ever find with about 600’ of total elevation gain and 1500’ of total elevation loss, all run on wide well groomed gravel bike trail. The associated 50K race will feature almost no elevation gain and 1500’ of total elevation loss, easily making it one of the fastest 50K races in the country. This is a perfect race to attempt your first 50K or 50 miler, and the perfect race for the most seasoned ultra runner to go after at 50K or 50M PR. All this on a well supported course, while running through the heart of the Central Cascade Mountains…what more could you ask for?

The 50 Miler will begin at South Cle Elum and will head west following the I-90 corridor on the Iron Horse Trail. The trail will gain minimal elevation over the first 29 miles (~600’). The first 12 miles will run near I-90 until you hit the town of Easton, where the trail will head along Lake Easton and the Yakima River and run through the forests of the central Cascades. At Mile 20, you will run through the Whittier Tunnel before hitting the scenic shores of Keechelus Lake at Mile 22. Prepare to be stunned as you run along Keechelus Lake for almost 6 miles, taking in jaw dropping views of the Cascade Mountains the whole time. Shortly after Mile 28, you will arrive at Hyak where we will have one hell of a party at an aid station to get you ready for the tunnel and your downhill finish. You will enter the tunnel at Mile 29, and emerge into the light 2.4 miles later. You will now begin your epic downhill journey with more breathtaking views as you drop 1500’ over the final 18 miles to the finish line. Your reward will be a high five and an amazing belt buckle to commemorate your 50 mile journey on the Iron Horse!

*The 50K race will begin at Hyak. The course will start with an out and back east along Keechelus Lake and will turn around after 5 miles. It will then follow the remainder of the 50M course.
