Race Overview
The Timberline Marathon circles Timothy Lake twice on the shoulders of Mount Hood, a singletrack trail course at roughly 3,000 feet in Oregon's Cascades. The route crosses the Timothy Lake dam and several rustic bridges before finishing near the historic Clackamas Lake Ranger Station. It runs every June alongside a 14.4 mile half marathon offered on both Saturday and Sunday. Negative Split organizes the race under a special-use permit with the Mt. Hood National Forest.
