Longest ramp jump on rollerblades (inline skates)

The longest ramp jump on rollerblades is 30 m (98 ft 5.1 in) and was achieved by Chris Haffey (USA), at the Palais Omnisport Marseille Grand Est, in Marseille, France, on 9 December 2011. Haffey used a wakeboarding zip tow to achieve the required speed for the jump, a novel approach as most attempts rely on a long downhill slope to build up the speed.
