The Ruff returns to Carson, Washington on November 22nd, inviting runners to challenge themselves with a unique course that ascends Dog Mountain before descending through the scenic trails of the Columbia River Gorge National Scenic Area. This event is not just about running; it's an experience that tests endurance and offers breathtaking views from high above the Columbia River.
Race day in Carson typically sees clear skies and firm trail conditions, making for a runnable but challenging surface underfoot. The race begins at dawn with temperatures around 7am expected to be mild enough for comfortable racing attire without overheating concerns. Participants can expect low UV exposure due to cloud cover or early morning shade along the trails. Since its inception, The Ruff has grown in popularity among trail runners seeking a memorable and rigorous experience that combines steep ascents with exhilarating descents. Over the years, it has attracted hundreds of participants who come not just for the physical challenge but also to support local causes and enjoy the camaraderie fostered by shared passion for running. The course at The Ruff is entirely on single-track trails within Dog Mountain Trailhead, offering runners a mix of natural beauty and technical terrain. Starting and finishing lines are both located here, with no aid stations along the route but plenty of opportunities to take in panoramic views of Mt Hood, Mt St Helens, and the Columbia River below. The elevation gain is significant at 3000 feet over three miles before descending for four miles back down. Weather conditions on race day will likely present firm trails due to recent dry spells or early morning frost that leaves a slightly soft underfoot feel as temperatures warm up through mid-morning hours.
