Get ready for the most picturesque marathon and half marathon trail running course in the Pacific Northwest! The course completely circles shimmering Timothy Lake on single track trails that are absolutely a runner's dream. This gem is nestled at 3,227 feet in the high Cascades and the views of Mt. Hood across the lake are extraordinary.
The journey begins at the Historic Clackamas Lake Ranger Station and takes runners on a magical course that traverses three rustic bridges over sparkling tributaries that feed the deep blue waters of the lake. The ever changing scenery and terrain create an experience that is unparalleled. The Timberline Marathon and Half Marathon is a must for any runner's calendar!
