Did the Don Marta favela (Portugese for "slum") not make your hit list the last time you visited Rio? (Something tells us an extra hour at Ipanema and a few rounds of Caipirinhas took precedence.) Well, now you can tour the typically inaccessible neighborhood on the back of downhill mountain bike, all without leaving the safety of your very (thank god) immobile armchair.

Equipped with tricked out full suspension rigs and a helmet cam, brotherly downhill duo Dan and Gee Atherton treat us to a dizzying descent of the harrowing hood, rolling over steep staircases, wiggling through tight, meandering alleyways and even jumping off church roofs. Blink and you might miss it.
