Watch: This gruelling Red Bull uphill swim challenge

A homegrown athlete beat 200 competitors to win a unique open-water uphill swimming race involving scaling canal lock gates. The Red Bull Neptune Steps race is the only competition of its kind in the world. Participants swim uphill through 420 metres of cold water and climb 18 metres over eight canal lock gates, helped by rope climbs, wooden ladders, cargo nets and climbing walls.
