Kerr’s battle with Jakob Ingebrigtsen will be a Paris 2024 highlight. The Scot’s coach Danny Mackey explains how to tweak his workouts to boost your parkrun sprint finish

Josh Kerr is one of the fastest middle distance runners in history. He is the world 1500m champion, the world record-holder over two miles indoors and Britain’s quickest man over a mile – ahead of Steve Cram, Sebastian Coe and Steve Ovett. But perhaps Kerr’s ultimate superpower is his ability to find even more at the end of his races, when his lungs are burning and his limbs are screaming.
