Before Renner took to Butler Field on the day of the Red Bull High Rise, he decided to practice hitting the ramp the previous day to regain the feeling of flying off a vertical take off and coming down on a landing that allows for no margin for error. The unique quarterpipe had to be transported from the Red Bull Compound in Southern California to Chicago, Illinois so Renner went without practice for over a week and with a jump this crucial, that can be a long time.
