So this is interesting. Colin McCourt was a professional UK athlete, ran in the 2010 commonwealth games, but stopped running in 2012 and 'had a baby and got fat'. PB is 14.50 5k six years ago, 4.14mile four years ago. He ran a 24 min 5k at parkrun last January.
He has a bet with friends that he can run sub 16 by the end of the year. If he does they'll each give him Â£100, if not he'll have their names tattood on his body.
