Official event pageWhat this race demands
The Baloise Namur Marathon demands complete marathon-distance endurance over a flat-to-rolling river route along the Meuse and Sambre.
Marathon distance
Covering the full 42.2 km distance requires sustained aerobic capacity and structural resilience to manage cumulative impact fatigue.
Spring endurance
An early April race date requires consistent winter base training to sustain steady pacing over several hours of continuous running.
A sustained effort of this duration requires consistent carbohydrate intake of 45 to 60 grams per hour to maintain glycogen stores through the finish in Namur.
