The race has been started up again after a six-year absence. Older or more nostaligic readers will remember a terrified-looking John Noakes taking part in the race for Blue Peter in the 1970’s.
Competitors start by hurling themselves off a ledge at the head of the glen, before plunging into the river and later dropping down a 9 metre waterfall at Lower Falls Leap (pictured). In between they must negotiate pinch points called Gurgling Gorge and Leg Breaker. Previous entrants have taken between 20 minutes and an hour to compete the event.
