Rio de Janeiro, Brazil · Sunday 2 June 2024
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.

Maratona do Rio is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are inherently slower than road courses due to uneven footing, technical sections, and often steeper gradients. Trail-specific shoes with good grip are recommended, and runners should expect a finish time 10-20% slower than their equivalent road marathon time.
Our difficulty rating for Maratona do Rio is calculated using a model that combines elevation gain, temperature impact, and surface type. Use the difficulty calculator above to enter your target finish time and see exactly how many minutes this course would add or subtract compared to a perfectly flat, cool, road-based marathon.
