The courses of the Baloise Namur Marathon and the Baloise Namur Half Marathon, which will take place on 12 April 2026, have been certified by World Athletics and the AIMS (Association of International Marathons and Distance Races).

The certification was carried out on 16 February 2025 by official surveyors, in the presence of the police to ensure safety. Both distances were measured in one go, without any problems, and with the necessary adjustments to ensure absolute accuracy.
