What this race demands
The NN Marathon Rotterdam requires sustained running fitness over a flat 42.2 km course designed for fast times.
Aerobic endurance
Covering the full 42.2 km marathon distance demands a well-developed aerobic engine capable of maintaining a steady pace for several hours.
Pacing discipline
The exceptionally flat elevation profile of 5 m eliminates significant climbing relief, requiring strict pacing discipline to avoid early muscle fatigue from a constant stride.
A sustained effort lasting several hours requires a consistent carbohydrate intake of 60 to 90 grams per hour to maintain energy levels.
