“Enjoy beautiful trails with three big climbs and a great view on a clear day.”— Tad Davis
Featured Race - May 11, 2019
A bank of clouds below the rocky cliff as you summit Mt. Constitution and green islands rising through the clouds like rocks in a wild sea make this race one of the most stunning trail half and full marathons in the Pacific Northwest. On the summit, there stands a stone observation tower built by the Civilian Conservation Corps in 1936. The tower offers panoramic views of the sea, islands, mainland, and the Cascades.
Some more runnable downhill and you'll hit Mountain Lake at mile 9. Hit the beautiful Mountain Lake Loop trail until you connect back to Cascade Falls Trail. Retrace your steps for just over a mile where you'll take a right which will take you to a parking lot. Cross the road and hug the hillside for the next mile or so watching for a Picnic Area sign. This will take you down to the road at Cascade Lake. Take a right past the restroom building and start the long, fairly rocky switchback climb to Cold Springs Trail. Take a left and run a flat beautiful trail for the next 2.5 miles.
Eventually, you'll come to an intersection where you can head straight to Twin Lakes but you'll take the right and start the last big climb to Mount Constitution. Top out on a road and head up it to the tower and overlook for fantastic views on a clear day. Head right from the direction you came and hug the cliff side which will take you back down towards Summit Lake. At about mile 20.5 you'll cross a paved road. Another half mile of running you'll have completed a big loop. Take a left and retrace the big, fairly rocky switchback climb you made earlier. This will take you back down to Cascade Lake Trail where you'll cross the road and head counter clockwise around the lake back to the start.
