What this race demands
The Zurich Maratón San Sebastián demands sustained pacing over a standard marathon distance on a flat, sea-level urban route.
Aerobic endurance
Completing the 42.2 km distance requires sustained cardiovascular output over several hours.
Musculoskeletal durability
The flat, urban course profile keeps loading repetitive and consistent, demanding high resistance to impact fatigue in the lower limbs.
Pacing discipline
Maintaining an even effort from start to finish is critical to prevent early depletion over the full marathon distance.
A target intake of 60 to 90 grams of carbohydrates per hour is recommended to sustain energy levels across the duration of the event.
