Not content with being the first person to solo kayak the Amazon, fearless Blue Peter presenter Helen Skelton attempted - and succeeded - in becoming the first person to high-wire walk between the chimneys of Battersea Power Station, in aid of Red Nose Day 2011.
Super Skelton had been secretly training for months for this once-in-a-lifetime high-wire adventure which tested her nerves, balance and determination to the absolute limit as she completed the crossing 66 metres up in the air, on just an 18mm thick piece of wire.
Holding the eight metre long balance pole, which weighs 8 kg, out in front of her was just one of the difficulties the 27 year-old will faced as she navigated her way across the 150 metre length of London's iconic landmark.
