Running the London Marathon

Before setting off to cycle round the world I ran the London Marathon, dressed -daftly- in a large rhino costume. My time of 4 hours 52 minutes was the winning time for a rhino that year.
This year I am running the marathon again, this time without a rhino suit, and I hope to knock almost two hours off my time.
My ambition is to run a sub-3 hour marathon. I am not sure I am a good enough runner to achieve this, but I will certainly be trying my best on April 22nd. I am raising money for Hope and Homes for Children once again, and you can sponsor me here if you are able. Thank you!
