Official event pageWhat this race demands
Maratona do Rio demands sustained pacing and structural durability over a standard 42.2 km distance along a scenic coastal course in Rio de Janeiro.
Aerobic Endurance
Covering the full 42.2 km marathon distance requires a high level of cardiovascular capacity and sustained energy output over several hours.
Structural Durability
The repetitive impact of continuous road running over the marathon distance places significant stress on the musculoskeletal system, requiring thorough preparation to resist fatigue.
A consumption of 60 to 90 grams of carbohydrates per hour is recommended to sustain energy levels across the multi-hour duration of the marathon.
