Marathon - This is Oregon's signature trail running event and you also earn Trail Runner Trophy Series points! The beautiful course follows a stunning segment of the Pacific Crest Trail from historic Timberline Lodge high on Mt Hood to shimmering Timothy Lake nestled in the high Cascades. There is a 3000 feet net elevation loss - yeah, it's like running downhill!
Half Marathon - Get ready for the most picturesque half marathon course in the Pacific Northwest! The Timberline Half Marathon completely circles shimmering Timothy Lake on single track trails that are absolutely a runner's dream. This gem is nestled at 3000 feet in the high Cascades and the views of Mt. Hood across the lake are extraordinary. Runner's traverse three rustic bridges over sparkling tributaries that feed the deep blue waters of the lake. The course is full of small elevation changes and twists and turns making it very interesting and challenging.
