Good Cause of the Day

Here is an incredible opportunity to abseil down Battersea Power Station in aid of Cancer Research UK on Saturday 31 August. As the charity describes it:

"Walk through the old turbine hall, up the derelict staircase, onto the roof and take in the breathtaking views of the London skyline. Turning your back on the view and fixing your eyes on the huge, iconic chimneys, you’ll descend down the walls of Britain’s largest brick building.'

Friends and family can cheer you on from the ground and when back on terra firma, participants can join a post-event reception. £30 registration fee with suggested £200 sponsorship, register online, Saturday 31 August at 8.30am
