It is March, so it is time again for the Cheltenham Festival, the annual horse jumping meeting in England. Malcolm Willstrop, a former horse racing journalist, takes Outside The Glass into a betting shop in Pontefract to put a wager down before spinning a few tales from his early days in squash. The dean of international squash coaches, Willstrop has been mentoring players for a half century, including Gawain Briars, Lee Beachill and his son, world No.9 James Willstrop.
