Marathon races near Flémalle

Night-Marathon Spa-Francorchamps allows runners to use the asphalt of the Spa-Francorchamps motor-racing circuit in Stavelot, Belgium, after dark. The event takes place in October on the famous circuit between Stavelot and Spa-Francorchamps, offering solo distances from a single 7 km lap to 14 km, half marathon, and full marathon. Relay options include 14 km for duos, 21 km for trios, and 42 km for duos, suitable for first-timers, club runners, and groups sharing the distance. The course utilizes the circuit itself, providing a straightforward appeal: participants run on the same asphalt typically used by cars and bikes, with pit boxes, racing lines, and the Ardennes air surrounding them instead of a typical road loop. Race numbers and pre-ordered shirts are collected at the registration desk on the circuit, food trucks are located behind the Formula 1 pit boxes, and spectators require advance visitor tickets. The location defines the race's primary characteristic: a night run on a motorsport landmark, distinct from a city-street race.

The Nationaal Park Marathon Hoge Kempen guides participants off-road through Hoge Kempen National Park in Maasmechelen, Limburg. This late-winter Sunday event offers four distances: 7 km, 14 km, 21 km, and 42 km, suitable for short-distance hikers, trail runners, half-marathoners, and marathon runners. The route highlights the park's unique landscapes, Belgium’s only national park. Participants can register online, find support along the course, and use chip timing. A portion of each registration fee supports nature projects within the park.

The Heuvelland Marathon takes place in Zuid-Limburg during March. Both the marathon and half marathon begin in Vaals, with all distances concluding in Gulpen. This is a hilly trail-running event, not a road marathon. The 42.2 km course involves approximately 943 metres of climbing, the half marathon has 456 metres of ascent, and the 14 km option still includes 287 metres of elevation gain. The route crosses diverse nature trails between Vaals and Gulpen, meaning mud is a possibility. Finishers receive vlaai, a local Limburg tart, instead of a standard medal photo. The event accommodates walkers via the Heuvelland Walk and includes relay teams of 2 or 4. Participants consist of local Dutch runners and international visitors. A recent edition saw a record 1,300 participants, and the marathon distance has been recognized for the UTMB Index.
