Racing Through the Rio Slums

Legendary mountain biker brothers Dan and Gee Atherton race through Dona Marta slum in Brazil in this video of Red Bull’s Favela Bike Race, “Challenge on the Hill.”

The 760-meter course of alleys and stairways dropped through an elevation change of 170 meters. The riders also had to contend with the stray dogs, chickens and humans that call this favela home.
