Tim Foxley has run marathons in London and New York to raise money for the alcohol and drug rehabilitation charity Phoenix House.
How did you get involved with Phoenix House? I ran the London Marathon in 1999, and the New York Marathon in 2000, for the National Asthma Campaign.
Then I broke my ankle, so I was out of action for a while. My brother ran the London Marathon for Phoenix House last year, and when this year's race came around, the charity had a spare place - so I decided to run too.
What do you like about Phoenix House? I get on really well with the people who work there, and I have a personal connection because my father had a drink problem.
I like that it tailors its packages to meet the people's needs, and I'm also keen to support smaller, less well-known charities that find it harder to raise money.
Why did you decide to run marathons for the charity? I used to watch the London Marathon and then one year my friend got me an application form. I thought it would be a good way to get healthy. It's actually an achievable and impressive goal. If I can do it, anyone can.
I have just also completed the New York marathon for Phoenix House, for which I promised to raise £3,000.
How much have you raised? So far, I have raised about £2,000 - I found it harder to raise money for the New York Marathon because it was so soon after the race in London, and my friends and family were not so forthcoming the second time round.
But I have made a promise and I will raise the remainder, even if it means putting in several hundred pounds of my own money.
Which marathon do you prefer? When I ran my first one in London, it almost brought me to tears. There was such a great spirit and everyone was really friendly - you never forget your first marathon.
The one in the USA is probably more colourful and less cramped, but the last marathon I did there was very hard because just a few days before I took part, one of the screws in the metal plate in my ankle came out and was floating around somewhere - it wasn't my best time.
