Thank you so much for reading this. All the money I raise in this knee-knocking endeavour will be for the Debbie Fortune Estate Agents' chosen charity for 2015 - Above & Beyond, whose target is to raise £6m to transform Bristol's Cancer Centre and the Bristol Royal Infirmary. Many of you, like me, will have friends or family who have had brushes with cancer, and the work at the Bristol Cancer Centre is absolutely vital if we want to beat this devastating disease.

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. So it’s the most efficient way to donate – saving time and cutting costs for the charity.

Oh, and make sure you add the Gift Aid as well, that doesn't cost a penny!

I really want to make a difference with your donations, so if you donate, I promise I won't close my eyes on the way down!
