The biggest hard enduro event in the world, the Erzbergrodeo, is set to take place June 15 to 18, 2017, in Eisenerz, Austria. Here, the world’s elitist racers will tackle four days of grueling hard enduro races. The highlight of this weekend’s proceedings is the Red Bull Hare Scramble where 500 riders start from the bottom of a quarry to battle their way to the top of Austria’s biggest iron mine.

“It may be one of the most technical races in motorcycle offroad, like motorcycle dirt bike racing, in the world,” said Colton Haaker.
