Cool start — fast day potential, big temp swing

A cool 49°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temps will climb significantly to 67°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.

Race Info

A stunningly beautiful course in the scenic town of Leavenworth, Washington. Marathoners will start near the renowned Alpine Lakes Wilderness Area. Runners will run a fast course that begins with a 10 mile journey through Icicle Canyon, transitions to trails along the Icicle River, passes through the National Fish Hatchery to East Leavenworth Road, crossed the bridge into the Bavarian Village of Leavenworth to follow wooded riverfront parks and trails, eventually meeting up with Icicle Road, which leads back to one more trip around the Icicle River trails and to the Finish and roar of the crowd at the Hatchery and event center. In this amazing course, runners will encounter a mix of paved roads and paths, dirt roads, paths and trails. Surrounded by impressive mountains, participants might see salmon spawning in the rivers or four legged creatures cheering from the edge of the wild! Source
