LDP stands for Long Distance (Skateboard) Pumping, also known as "Skumping." Longboard-skateboard technology has rapidly advanced since the 1970's, and along with those changes is a new breed of distance-pumping skateboarder.
LDP sessions can be casual 5- to 10- mile pump cruises on flat bike / rollerblading trails, or a 26-mile all-out marathon, where a gyrating, pumping motion is the primary means for moving the skateboard forward!
