Going updates The eyes of the racing world will be firmly fixed on Epsom at 3.30 for the Betfred Derby (In Honour Of His Highness Aga Khan IV) but Punchestown and Navan ensure it's a busy day on the home-front also. Punchestown, with an 8-race jumps card, is first into the fray at 1.10. Following watering and 5mm of rain, the going at the County Kildare track is described as good to yielding. The possibility of 5 to 8mm (approx) of rain today, is the forecast on the weather front. Meanwhile light showers throughout the afternoon are expected at Navan, where a 7-race Flat programme is scheduled to begin at 2.00. At Proudstown Park it remains good, good to yielding in places.
