He says: “Hi.
“Last year I asked for your help to raise money for the Food Bank and Grantham Passage. Well, I wanna go again!
This time though, this not quite so fat boy will be RUNNING 2 to 4 times a week and hopefully finish with a 5k in the Christmas week maybe dressed as Santa for a bubble.
“Please, I know times are hard for everyone but there even harder for some others out there if everyone on my Facebook and Instagram donate £1 I’ll smash my target.
“If anyone would wants to get involved holla at me”
