Mountain Lakes 100
September 26, 2025 @ 5:00 pm - September 28, 2025 @ 2:00 pm PDT
An event every year that begins at 5:00 pm on day fourth of September, repeating until September 28, 2025
One of the country’s most beautiful 100-mile races starts at Clackamas Lake Historic Ranger Station (instead of the usual Olallie Lake, due to fire damage) and runs mostly along the Pacific Crest Trail. This race features the best trail running Oregon has to offer – technical and rocky sections, views of mountain peaks and lakes, and luscious sections of single track on the Pacific Crest Trail.
If the area around Olallie Lake is recovered enough to host the event from there, we will. We’re assuming it won’t be and are planning to use the Clackamas Lake Historic Ranger Station again in 2022.
