WHO AND WHAT
"The centrepiece of The Great Climb will be an attempt to make a brand new extreme route up Hell's Lum Crag by one of the world's very best climbers, Dave Macleod. He'll be ably partnered by fellow Scot Dave 'Cubby' Cuthbertson.
Meanwhile, across the corrie floor on the majestic Shelter Stone Crag three other teams of elite climbers (plus one beginner!) will follow established but spell-binding routes up this intimidating precipice.
Canada's Barry Blanchard and Spain's Araceli Segarra will climb the long, hard classic route 'Steeple'. Leading South African climber Ed February will partner new school Sheffield-based climber Ben Heason to climb a modern extreme route 'Stone Bastion'. Finally local mountain guide Graeme Ettle will show climbing newcomer Jenny Graham the ropes on the half-century old test-piece 'The Citadel'.
It promises to be a day to remember – not just for the climbers – but for the millions of viewers worldwide tuning in or watching via the internet."
