Many of the Olympics venues were built around the Parque Olímpico in the Barra area. One can put together a 4 km loop around the paths around the athletic park’s facilities, which includes a tennis center, velodrome, pool, arenas, & more. It’s fun to run on the Via Olimpia to the Cabo da Pombeba viewpoint.

For a longer run, head across the way to the Rio 2 Park/Parque Linear Cidade Jardim, which has a ~1.5 km cycle path that’s decent for running. It’s 2.5 km from Parque Olímpico, using the sidewalk along Av. Embaixador (not that pleasant, but runnable). Combined, this is an 11.3 km route.
