Guy is a trustee for Sporting Tree Foundation, and this year has decided that he is going to push his body to the limit and run the 2019 Virgin London Marathon on Sunday 28 April in order to raise funds for us.
Guy has been training since last year, and has been taking part in a number of races as part of the intense training programme that he is putting his body through.
The mass race starts at 10:00 from Blackheath and Greenwich Park. Guy will run 26.2 miles hopefully within his goal time of under 5 hours, and will finish the race outside Buckingham Palace.
We are all exceptionally proud of Guy for dedicating himself to this, and we will all be there to watch him finish on the day!
