After becoming the 89th best stair climber in London at the RNLI Tower Run last year, I thought I'd challenge myself once again. This time I'll be going along rather than up, as I tackle the Thames Bridges Trek.

25 kilometres.

16 bridges.

1 great cause.

Which cause, you ask? I'll be doing this for Great Ormond Street Hospital, one of the worthiest causes I know. They've looked after the children of friends of mine, providing care and kindness that is second to none. I went to the hospital several times during my brief spell as an ambulance driver: even though the children there are facing the fight of their lives, I've never experienced a place that is so full of hope. Their ethos is that being sick doesn't mean you have to be sad, and I think we can all get behind that.

Any donation, big or small, will go to supporting this truly great institution as they continue their fantastic work.
