Helen Skelton's Completes Bird on a Wire Challenge

Blue Peter viewers will be able to watch presenter Helen Skelton's record-breaking high-wire walk between the chimneys of Battersea Power Station tonight at 4.30pm ON BBC One.

Helen will be available for a live web chat straight after the show - and you can send your questions in now!

The 27-year-old navigated her way across a 150 metre gap on a piece of wire the same diameter as a 10p piece - all at a height of 66 metres.

The feat, which took just 14 minutes to complete, notched up another record for Helen for the highest female wire walk in the UK.

Helen said: "I’m so proud of myself for managing to keep my nerves in check and not wobbling on the wire. There were a few hairy moments when I had to stop myself from looking down and concentrate on the end of the wire.

"I can’t lie, I was incredibly nervous staring over the edge waiting to begin but as soon as I stepped off it was an amazing rush. The training has been tough and I have never had so many bruises in my life but it has been totally worth it. The fact that I’m doing it in support of Red Nose Day was a great incentive throughout the whole experience."

Helen's experience was filmed for a special documentary entitled Comic Relief: Girl on Wire which will be shown on BBC One on Friday 11th March at 7.30pm. There are also two Blue Peter specials on March 7th and 8th.

Last year Helen became the first person to solo kayak the Amazon as part of her fundraising efforts for Sport Relief.
