Nine-time World MotoGP Champion Valentino Rossi has organized the Motocross dei Campioni event at Cavallara in Italy and participated at the charity run in order to raise funds and help treat children suffering of leukaemia at a hospital in Pesaro, Italy.

The event gathered more than 10.000 people, among which Andrea Dovizioso, Julian Simon, Marco Simoncelli, Loris Capriossi and Marco Melandri were the other names associated with motorcycle racing.

Looks like The Doctor is no stranger to dirt riding either, as the attached video shows.
