I have just come back from 2 weeks in Brazil. I took my running gear but only did 3 runs in total. A bit disappointing really.... However, my last run before flying home was right along Ipanema beach. It was 0730 and already 24 degrees! I did 5k, albeit I didn't break any records! What amazed me about Brazil and certainly Ipanema and Copacabana, was that they have purpose built cycle lanes which are also running lanes. They're shared (very courteously) by both. There were dozens and dozens of us running. I felt absolutely at home, I felt safe, nobody stared at you, no wolf whistling or idiots driving by hanging out of car windows shouting abuse! And the views, well they're unsurpassed. I fell in love with Brazil. It's a very chilled out country with a love of sport... Any sport. If ever you get the chance to go to Rio, take your running gear, you'll regret it if you don't.
