The biggest names in skateboarding are returning to Detroit’s Hart Plaza for the third edition of Red Bull Hart Lines. Contest visionary, Ryan Sheckler, and an elite roster of invited pros will take on the unique two-lane course and put their skills on the line in front of a packed Detroit crowd. The course will be comprised of two lanes, each with its own unique set of skateable features. Athletes get to skate each lane once, then for their third run, the choice is theirs. The top score from each lane based on style and skill is averaged and then balanced against the quickest time. Follow along with #RedBullHartLines and watch it as part of the Red Bull Signature Series, LIVE, only on Red Bull TV Saturday, May 13 or as a highlight program on NBC on Saturday, June 17 at 4:30 p.m. EST.
