In a summer of world class sporting events, tennis players have been battling it out at Wimbledon - one of the four major Grand Slam tournaments. One of the big stories has been the success of British wildcard entry Arthur Fery who, before Wimbledon, was ranked outside the top 100. His success has come with a big jump in prize money - essential to pay for the international travel, accommodation and coaches required to keep climbing the rankings. For those lower down the ranks, life on the professional circuit can be tough both emotionally and financially. Hamish Stewart, from Scotland, is currently ranked 300 and is all too aware of the personal demands of the job. "I've just missed an ex-college teammate of mine's wedding," says Stewart. He is joined by Jamie Loeb from the US, who is currently ranked outside the top 1,000. She had a career high of 132 and played in the US Open before injury and personal circumstances stalled her rise. We also hear from three coaches - Viktoria Belinsky, Noelle van Lottum and Michael Logarzo - who give us an insight into their jobs, the sport and its parallels with life.
