Red Bull Quicksand

Red Bull Quicksand could be the toughest 1 mile you’ve ever run. Set on the beautiful sandy beaches of Durban, competitors run through the special course filled with giant sandcastles in an energy-sapping knockout format, with heats, semi-finals, and finals.

On top of the obvious challenge that comes with running on sand (runners expend up to 1.6x more energy on sand than running on a road surface), the course is rigged with giant sand castles, trenches and rollers, giving competitors a real test of endurance, acceleration, and bursts of speed.
