Not content with being the first person to solo kayak the Amazon, fearless Helen Skelton reveals today that she has set her sights high for her latest challenge; she will attempt to become the first person to high-wire walk between the chimneys of Battersea Power Station, in aid of Red Nose Day 2011. 

Helen has been secretly training for months for this once-in-a-lifetime high-wire adventure which will test her nerves, balance and determination to the absolute limit as she completes the crossing 66 metres up in the air, on just an 18mm thick piece of wire.

Holding the 8 metre long balance pole, which weighs 8 kg, out in front of her is just one of the difficulties the 27-year-old will face as she navigates her way across the 150 metre length of London’s iconic landmark.

 “The last few weeks training in France have been really intense. It's nerve wrecking and physically exhausting, but I feel ready and I just want to get on with it,” she admits. “I’ll be attached to a device like a seatbelt that will kick in if I fall off, I won't be able to feel or hear it, so it really will just feel like me and my balance pole alone on the wire, more than 50 metres up!”

Helen hopes her incredible effort will inspire others to do a fundraising activity this Red Nose Day and help raise money that will change lives forever.

Helen will attempting her challenge on Feb 28th. Go to www.rednoseday.com/girlonwire to support her in this incredible fundraising effort and tune in to two Blue Peter specials on March 7 and 8 to see if Helen gets a head for heights at Battersea Power Station.
