Baloise Namur Marathon

Namur, Belgium · Sunday 25 April 2027

Official WebsiteRoadFull Marathon

Namur's position at the confluence of the Meuse and Sambre rivers in Belgium's Walloon region makes it a compelling marathon destination. The city itself, dominated by the imposing Citadelle that overlooks the valley, sits within a landscape of gentle river valleys and forested hills that characterize the wider region. This corner of Belgium offers runners the chance to experience the quiet, less-touristed side of the country, where medieval architecture and natural beauty coexist without the crowds you'd find further north. The surrounding countryside provides genuine scenic interest without the extremes that might punish slower runners or those recovering from training. The course itself reflects this landscape beautifully. At 42.2 kilometers on trail surfaces, it's a full marathon that stays mostly flat to gently rolling throughout, with only 136 meters of elevation gain spread across the route. Runners will spend the day between 75 and 111 meters above sea level, meaning there are no significant climbs to break rhythm or derail pacing strategies. For a trail marathon, this is genuinely approachable terrain. The decision to run on trails rather than roads softens the impact on your legs while maintaining the speed-friendly gradient profile, making this a course that rewards steady effort rather than technical footwork. Race day itself benefits from the event's established infrastructure and community focus. Beyond the main marathon, the Baloise Namur Marathon hosts a semi-marathon, 10K, and various other categories including the KickCancer element, which gives the event a social character. The organizers provide multiple ways to stay connected during the race, from live tracking to video support options, suggesting they've thought through what both runners and their supporters need. With logistical support including accommodation information and garderie facilities, this feels like a well-managed event that understands the logistics of gathering runners from across Europe.
