I picked this charity because it's personal to me. This illness has hit both sides of my family, and I’ve seen just how devastating it is and what it does to someone's life. 1 in 11 people over 65 in the UK have dementia, and for those 85 and over, it’s closer to 50%.

As a PE teacher, I know that I should be leading by example with keeping fit. However, the classic excuses of having two young children and a busy work life have really hit me over the last 5-10 years! I know that in order to get fit again I needed to set myself a challenge and then try and work hard towards it.

I really don't like running—I've tried so many times to get into it, but it's never stuck. So, deciding to do this is a massive effort and a real challenge for me, but something I've always wanted to achieve. A huge thank you for your time and generosity in donating to this worthwhile cause. It really is appreciated. Nick
