Shot on the actual streets of San Francisco, California, GYM5 features a focus on fast, raw and precise driving action. Filmed over four days, the entire city of San Francisco is Ken Block’s personal gymkhana playground. DC Shoes also provided fellow DC athlete and longtime Ken Block friend, Travis Pastrana, to make a cameo appearance on his dirtbike, and S.F. resident Jake Phelps of Thrasher Magazine fame also makes a cameo as Block hoons S.F. in GYM5.
