Cool start, warming finish

Runners will face a cool start at 48°F, gradually warming to 70°F by the finish. Light winds from the east will have minimal impact on performance. With humidity at 61%, it's advisable to pace conservatively early on, especially during the initial miles with headwinds. The terrain provides a beneficial tailwind from miles 11-13 and 21-25, aiding the descent toward the finish.

This course drops 4,931 ft from start to finish, so we forecast it at 3 points, not just the start line. At 9:00/mi, you start at 46° and finish around 10:55 AM in 62°; the start line's forecast says 57° then.

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
