The Shelter Vertical Rush challenge is simple.  Climb the 920 steps - 42 storeys - of the Nat West Tower in the City of London as quickly as possible.

Its going to be tough - so will need lots of donations in order to give me the motivation when I start feeling puffed on the 7th floor!

As they say - Donating through JustGiving is simple, fast and totally secure. Your details are safe with JustGiving – they’ll never sell them on or send unwanted emails. Once you donate, they’ll send your money directly to the charity and make sure Gift Aid is reclaimed on every eligible donation by a UK taxpayer. So it’s the most efficient way to donate - I raise more, whilst saving time and cutting costs for the charity.
