Maratona do Rio

Rio de Janeiro, Brazil · Wednesday 2 June 2027

Official WebsiteRoadFull Marathon

Running the Maratona do Rio 2024 means spending most of your morning on trail rather than asphalt, which changes everything about how your legs feel and how you need to pace yourself. The course sits low, barely climbing above sea level in most places, but those modest gains add up across 42 kilometers on uneven ground. You'll be constantly adjusting your stride on the trail surface, engaging stabilizer muscles that road running doesn't demand, and your quads will take a different kind of beating than they would on pavement. The June winter in Rio means cooler temperatures than you might expect, though humidity will still be present. The terrain itself keeps you honest; you cannot zone out and run on autopilot the way you might on a road marathon. The landscape around you is distinctly Rio, with the city's natural topology revealing itself through the vegetation and the way the land slopes beneath your feet. What makes this marathon memorable is the sensory experience rather than any single dramatic landmark. You'll notice the quality of light filtering through the trail canopy, the smell of earth and vegetation, and the way the ground changes texture under your shoes as you move through different sections. The moderately hilly profile means you get real climbs to push through but nothing that grinds you down relentlessly, though the cumulative effect of 201 meters of gain spread across the full distance is real by kilometer 35. Running here feels less like conquering a course and more like moving through Rio's natural geography, which is a fundamentally different experience from the typical marathon circuit. Your body will remember the trail work long after your legs recover.
