Nick is joined in this special edition by Patrick Cummings, Director of the Thoroughbred Idea Foundation, to discuss the plethora of challenging news stories to emerge from US racing in the past few weeks, from the imprisonment of Jorge Navarro, through the many twists and tragic turns of Bob Baffert and Medina Spirit, to the threatened stability of the new Horseracing Integrity and Safety Act. Later in this edition, in the company of Rishi Persad, Nick looks ahead to this weekend's Tolworth Hurdle, talks to trainer Ryan Potter about his leading contender J'Etoile, and considers whether the hype surrounding Constitution Hill is actually a positive for the sport.
