On Sunday 26th April, Dan Preston-Routledge will set off from Greenwich on the 26 and a bit miles of the Virgin Money London Marathon, hoping to finish in one piece on The Mall.
The day before, he is hoping to play in the last fixture of our season, at home to Rosslyn Park.
At the start of the season, he reckoned he weighed 118 kg, and while we know he’s been in training for this, he’s still not built like a typical Marathon runner!
He is doing this to support the Multiple Sclerosis charity and you can read all about his reasons for doing this
Hopefully everyone who reads his story will feel able to contribute to his fundraising campaign.
To help Dan, the Titans Community Foundation are donating one of their limited edition Christmas shirts to the supporter who gets the closest prediction to his actual time - and we hope everyone who enters will make a donation as well.
So how long is it going to take Dan to get round the course?
Tell us your best guess on social media - Twitter, Facebook, Instagram, or by emailing tcf@titans-rugby.com
Good luck DPR!
