Semi Marathon d'Hérinnes

Engineered for speed and scenic tranquility, the Semi-marathon d'Hérinnes returns to the ACRHO calendar on Saturday, March 28, 2026. Starting at 15h, this 21.1 km classic is a favorite for runners seeking a personal best on a remarkably flat course. Set in the quiet countryside of Warcoing, the route takes participants through pastoral roads and along the serene "RAVeL" paths following the water’s edge. Aside from a single bridge crossing, the asphalted track offers a smooth, high-cadence experience through the heart of the Walloon landscape, making it a must-attend event for half-marathon specialists in Belgium and Northern France.

The race infrastructure is centered at the Complexe Léon Velghe in Warcoing, providing a professional and welcoming environment for athletes. With the start and finish lines located on Chemin Quinze, the event is designed for logistical ease, offering on-site changing rooms at the local football grounds and convenient parking throughout the village. The course's technical profile is intentionally minimalist—primarily high-quality asphalt with only two brief paved sections—allowing runners to maintain their rhythm without distraction. Under the expert organization of the ACRHO team, the event promises a rigorous yet convivial sporting challenge that celebrates the spirit of regional road racing.

To ensure peak performance, the 2026 edition features a comprehensive hydration and nutrition plan, with four strategically placed refreshment stations at kilometers 4.6, 9.9, 14.3, and 18. Upon crossing the final timing mat, finishers are treated to a generous spread of tea, oranges, gingerbread, and fresh fruit to aid recovery. Whether you are aiming for the top of the ACRHO standings or simply looking to enjoy the breezy canalside paths, the Semi-marathon d'Hérinnes offers a triumphant and well-supported journey. Registration is managed through the ACRHO platform, and with its reputation for being "totally flat," this race is expected to attract the region's swiftest "fireflies" on the tarmac.
