I'm walking a marathon in the freezing cold to raise money for Great Ormond Street hospital. This amazing place saved the lives of both my dad, in 1948 and my sister in the 1970s. They have helped lots of people over the years and have been especially amazing this year where they've supported close friends of ours through a very difficult time.

I know money is tight for everyone but if you could spare a few pounds, I'd be so grateful.
