The Three Frontiers Half Marathon 2026 is one of those races that goes beyond the time on the clock. The event brings together sport, tourism, and integration between three countries on a route that passes through Paraguay, Brazil, and Argentina, turning the race into a unique experience for athletes and visitors. The 2026 edition is scheduled for October 11.
More than a competition, the race is an opportunity to experience the energy of the trinational region, cross important bridges, and run through settings that are part of the identity of Foz do Iguaçu and neighboring cities.
What will the Three Borders Half Marathon route be like?
The main race will be 21 km and, according to the information released, the start is scheduled to take place in Ciudad del Este, Paraguay, in front of the city hall. From there, runners head toward the Friendship Bridge, entering Brazilian territory through Foz do Iguaçu.
Most of the route will take place on roads in Foz do Iguaçu, continuing toward the Tancredo Neves Bridge region, which connects Brazil to Argentina. The finish line is expected to be in Puerto Iguazú, near the Argentine obelisk of the Three Borders Landmark.
For those who wish to participate in a shorter distance, there will also be a 10.5 km option, starting on Avenida das Cataratas in Foz do Iguaçu and finishing in Argentina.
Why is this race so special?
The Three Borders Half Marathon stands out for offering a rare experience: running on a route that connects three countries in a single race. For many athletes, this turns the race into a memory of travel, achievement, and contact with different cultures.
In addition to the physical challenge, the event also highlights the urban and tourist landscape of the region, passing through symbolic border points and creating an atmosphere unlike traditional races.
Tips for those participating in the Half Marathon
1. Organize your documents in advance
Since the race involves passing through border areas, it is important to check in advance which documents will be required to travel between the countries. Keep your personal documents in good condition and easily accessible on race day.
2. Plan your arrival at the starting point
The main race starts in Ciudad del Este, Paraguay. For this reason, it is worth organizing transportation in advance, calculating travel time, and considering possible heavier traffic due to the event.
3. Prepare for different sections of the route
As this is an international race, the route may involve different types of roads, bridges, and changes in pace. Training with terrain variations and simulating longer stretches can help your body adapt better on race day.
4. Take care of hydration and nutrition
In the days leading up to the race, maintain a balanced eating and hydration routine. Avoid trying very different foods on the eve of the race and prioritize meals you are already used to eating before long training sessions.
5. Rest well before the race
Sleeping well is an essential part of preparation. Since many runners come from other cities, the ideal is to arrive in Foz do Iguaçu with enough time to rest, pick up the kit, understand the race logistics, and avoid last-minute rushing.
6. Enjoy the trip calmly
Foz do Iguaçu is a destination that combines sport, nature, shopping, gastronomy, and cultural experiences. Those coming for the Half Marathon can take advantage of the trip to visit Iguazu Falls, the Three Borders Landmark, the city’s tourist attractions, and also enjoy tours throughout the trinational region.
