Woodford Green TV star Lydia Bright is set to scale new heights for children’s charity Barnardo’s by climbing to the top of London’s iconic Cheese Grater, known officially as the Leadenhall Building.

The former TOWIE legend, who is an ambassador for Barnardo’s, will climb all 1,250 steps of the skyscraper as part of the charity’s first urban summit challenge along with her brother Freddie on Saturday, December 1.

The pair will be joined by 100 other participants who will be hoping to raise as much money as possible to help Barnardo’s support some of the most vulnerable children and young people in society.

Ms Bright said: “I’m super excited to be scaling the Cheese Grater for Barnardo’s and I really hope my feet survive this challenge.

“Barnardo’s is such an amazing charity which is very close to my heart.

“I know at first-hand the wonderful work they do helping vulnerable children and young people.”

Several people have already pledged to climb the Leadenhall as many as ten times - the same as walking to the peak of Californian rock face El Capitan – 12,500 steps in all.

All those taking part are asked to raise a minimum of £200 for Barnardo’s.

Jennie York, Barnardo’s director of fundraising, said: “All the money raised will be used to support children who are affected by some of today’s most urgent issues, such as sexual abuse and exploitation as well as those who care for a sick or disabled relative and those who are leaving care.”

People are encouraged to sign up for a single ascent of the building.

Participants will receive a training plan, a fundraising guide, a Barnardo’s t-shirt, a finisher’s medal and a photo.

All those who complete the challenge will be invited to a celebratory event where they can take in the views of London’s skyline and enjoy refreshments.
