What you need to know to start your day including going from all the tracks

The most important tactic today is to pace yourself, especially if the Open golf takes your fancy from dawn to dusk, because the best racing comes well past teatime.

If the wind gets up at all round Birkdale, the first-round leader of the British Open will probably be known by the time they go to post for the day's feature Group 3 at Leopardstown, which matches Grade 1 winner Deauville against one of his trainer Aidan O'Brien's old adversaries, The Grey Gatsby.

Yes, that it the same popular grey who pipped Australia in the Irish Champion under Kevin Ryan's auspices nearly three years ago having also won the French Derby. The six-year-old is now in the care of Dermot Weld, who won this feature most notably with Famous Name, who reeled off a hat-trick.

What's on today

After Chepstow, Hamilton and Leicester provide the afternoon action Doncaster and Epsom take over in Britain with Leopardstown taking top billing with the Group 3 ICON Meld Stakes (8.0).
