Considered one of the worlds toughest races, the Red Bull 400 is returning to the iconic 35-degree, 470 foot ski flying hill at Copper Peak in Ironwood after a six-year hiatus. The event has been held at Copper Peak twice before, in 2018 and 2019. The popular spring race is scheduled for May 10 this year. More than 800 participants from all over the globe are expected to start at the bottom and race 400 meters uphill to the top of the largest artificial ski jump tower in the world. The nearly vertical race challenges athletes speed and endurance. Find out more about the race and register at redbull.com.
