Course & Elevation
The Meia Maratona Internacional do Rio de Janeiro, marketed in English as the Rio Half Marathon, is a point-to-point half marathon along the South Zone seafront of Rio, held on a Sunday morning in August. It is organised by Yescom, and the 2026 race was the 28th edition. The 21 km starts in Leblon and finishes at the Aterro do Flamengo, by the Monumento aos Pracinhas. The organisers describe the course as fast and technical, and the 2026 route took in the seafront at Copacabana and the Sugarloaf (Pão de Açúcar) area. They have announced a new route for the next edition, so earlier maps may no longer apply. A 10K and a 5K run on the same morning in the Aterro do Flamengo, finishing at the same place as the half marathon. The first edition was in 1997, and in 2008 the race doubled as the World Half Marathon Championships. In 2026 it counted towards the Brazilian road running championship. The course records on the organiser's list are 59:57 for Geoffrey Mutai in 2013 and 1:07:17 for Paskalia Chepkorir in 2012. It is a separate event from the half marathon of the Maratona do Rio, which is held in June.
