Cool morning, warming finish

Runners will face a cool start at 47°F, gradually warming to 64°F towards the finish. Wind will be light at 6 mph, with tailwinds expected between miles 5-10, offering a beneficial boost. However, the course's descent will help maintain pace, especially during the early miles. Hydration is essential as temperatures rise, and runners should consider a conservative start to adapt to the warming conditions.

This course drops 1,322 ft from start to finish, so we look at it at 2 points, not just the start line. In a typical year, at 9:00/mi, you start at 47° and finish around 10:55 AM in 64°; typical start-line conditions say 60° then.

About the Leavenworth Marathon

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
