Official event pageWhat this race demands
The TREK Antwerp Marathon requires sustained running endurance over a flat 42.2 km city course in mid-October conditions.
Aero and Pacing Discipline
Because the course is flat with only 57 meters of elevation gain, success depends on maintaining an even, unbroken pacing strategy rather than managing major climbs.
Impact Durability
Covering the full marathon distance of 42.2 kilometers places high mechanical stress on the musculoskeletal system, requiring thorough preparation for late-race fatigue.
Averaging 60 to 90 grams of carbohydrates per hour is recommended to sustain energy levels across an expected finish duration exceeding three hours.
