Nick and Lydia also reflect on the absence of L'Homme Presse and touch on one or two who perhaps shouldn't be running. Coolmore Australia's Tom Magnier joins the show to discuss the shuttling of City of Troy, while jockey David Egan looks ahead to a potential piece of history on Lincoln day, while his weighing room colleague Richard Kingscote reflects on a superb treble at Sha Tin in Hong Kong yesterday. Newbury's George Hill tells Nick about significant prize money increases this season, plus BHA Director of Equine Science and Welfare James Given draws today's show to a close with an in-depth look at new anti-doping protocols and their potential impact.
