The 25K course starts in the same place as the 50K, but instead of heading toward Timothy Lake right away, this route will take you across Forest Service road 42 onto the Miller Trail for a short stint. Then you’ll enter new territory, continuing straight onto the Headwaters Trail. This trail is not a part of the 50M or the 50K and takes you around Clackamas Lake. You’ll cross road 42 again, near the Joe Graham horse camp, and then run on the Old 1916 Trail. Here you’ll have a few climbs and descents until you reach the first aid station at mile 5.7. From there, you’ll run about another mile to connect with the Timothy Lake trail. The soft trail takes you around the north side of the lake to the Dam aid station at mile 11.3. Then you’ll continue around the lake to the finish line.
