Nick is joined by ITV Racing broadcaster Rishi Persad for a look at today's racing headlines. 48 hours away from the St Leger, Frankie Dettori has chosen to ride Arrest in the big race to the surprise of many. Nick talks to trainer John Gosden (also has news on Mostahdaf) and rider Kieran Shoemark, the beneficiary of Dettori's decision not to ride Voltigeur third Gregory. He also catches up with Juddmonte racing manager Barry Mahon, who additionally provides news on Westover, Chaldean and Nostrum. Later in this episode, as part of National Racehorse Week, Irish Field journalist Helen Sharp tells Nick about Racing to Relate, while Charlie Fellowes explains why he has had to get heavy with certain colleagues to get on board with the Newmarket Open Weekend.
