Pumping is a skateboarding technique used to accelerate without the rider's feet leaving the board.
Flatland pumping is essentially carving with the proper amount of weight application in order to gain momentum.
It involves shifting weight in sync with the board's movements in order to gain momentum, like pivoting, but with all four wheels on the ground.
LDP riders have been breaking world distance records for 24-hour skating, using a combination of pushing and pumping.
The women's world record is held by Saskia Tromp with 262 miles, also at the 2017 Dutch Ultraskate [2]
