Rio de Janeiro Marathon is by far the most scenic and beautiful in South America. The course is one of a kind: you run most of the time side-by-side along the beautiful beaches of Rio de Janeiro.
Visiting Rio (where 2016 Olympic games took place) is already a must-do if you are looking for destinations in South America. If you like to run marathons around the world, then, it's the perfect opportunity! Thousands of runners from USA, Canada, Mexico, Argentina and many other countries come every year to Brazil to run this race.
Be prepared: Rio is hot and humid. But the aid stations do a very good job in providing cold water every 5km or so.
This was my first marathon in 2008 and this year I came back to run it again.
