As a passionate sports' fan and punter, it was an easy decision for Jack to move from the City and accept a job at Betfair, where he worked for four years in various roles, before heading off to work with racehorses in the flesh.
He’s written about sports and betting for two decades, winning the Martin Wills Award for racing journalism in 2002 and writing Winning on Betfair for Dummies, first published in 2006 and now in its second edition, having sold over 35,000 copies in two languages.
As well as racing, his punting tends to centre around tennis, athletics and cycling.
He currently works in academia and, having interned for the Democrats in Washington DC during the Lewinsky scandal, finds it hard to resist the odd political punt.
