The trio were there to cheer on Monbeg Dude, a horse Tindall purchased a couple of years back before persuading Sinbad and Nick to come on board.
Monbeg Dude did win shortly before Christmas but couldn't repeat the feat this time around although ran well and was placed.
Under leading Grand National winning Jockey Tom Scudamore, Mondeg Dude finished in third place in a nail biting finish in the fourth race the Oakley Coachbuilders Handicap Chase behind Glens Boy (1st) and Ikorodu Road (2nd).
Despite the disappointment, the Gloucester players still had an enjoyable afternoon as they relaxed before taking on Toulouse at Kingsholm in the Heineken Cup on Friday evening (kick off 8pm).
Newbury's next fixture is Betfair Super Saturday on 11 February, featuring the Betfair Hurdle, Europe's richest handicap hurdle and the Betfair Denman Chase.
