Interview: MATT MANTLE Matthew Mantle is a professional in-running punter. He doesn’t work from a box on the racecourse or in a super fast trading room but from a cottage in remote and rural Devon. He has made it pay from a position that most people would imagine impossible, at home. It isn’t. Matthew explains how he beats the in-running book day in and day out with tips for those who might want to emulate him. Meeting Matt Mantle. (interviewed by Simon Nott)
