After numerous editions over the past eight years, Red Bull 400 is set to conquer 19 ski jumps across Asia, Europe and North America, putting racers from every continent under the most grueling physical pressure they'll ever face.

Today ambitious athletes from all over the world come to join Red Bull 400, an unbelievably intense race, and can participate in two main categories: full-distance solo for men and women and a co-ed relay (4x100 for men and mixed gender).
