Ready to watch ultra-marathoners run a 50K? The McKenzie River Trail Run is in its 32nd year of supporting ultra-runners as they make their way up and down the McKenzie River National Recreation Trail among old-growth forest and along a rushing river. The course begins at Carmen Reservoir off Hwy 126, just below Koosah Falls and Icecap Campground. Runners go upriver past the falls and around Clear Lake before returning down the length of the trail to finish across the road from the McKenzie River Ranger Station. Registration is now closed for participants, but it is always fun to watch the competition as runners make their way through the forest and next to towering waterfalls.
