The fastest non-motorized sport in the world! Competitors can reach speeds over 300mph by orienting their body in the most aerodynamic position possible.
During competition, they each have 8 jumps to attempt their fastest speed. This is measured by a Speed Measuring Device worn on their helmet. This device has GPS positioning and the judges can use the data to view the speed reached on each jump. The fastest 3 seconds for each jump is what is used to determine their score.
