A lapped course along the Lake Washington shoreline at Seward Park. The half marathon is two laps, a 6.9-mile lap with a steep hill followed by a flat 6.2-mile lap; the 10K pairs a 3.7-mile hilly lap with a 2.5-mile flat one. The 5K takes in a short steep hill early on. Aid stations every 2 to 3 miles with water and nutrition.
