About
The Timberline Marathon takes place in Government Camp, Oregon, over a weekend in early June, with a trail marathon (26.2 miles) at 8:30 a.m. on Saturday and a half marathon at 9:30 a.m. on both Saturday and Sunday. The half is listed at about 14.4 miles, so expect it to run longer than the standard distance.
The route circles Timothy Lake in the Pacific Northwest on single-track trails with views of Mount Hood in the High Cascades. Runners start at the Clackamas Lake Historic Ranger Station and cross rustic bridges over small tributaries, with varied terrain along the way. Finishers receive a medal and a gender-specific technical shirt. Snow can linger at elevation in early June, so be ready for mud and cool air.
