Ascot racecourse has announced the Queen's Vase at next week's Royal meeting will be run in memory of Sir Henry Cecil, who died on Tuesday.
With 75 victories, Cecil was won more races at the Royal meeting than any other trainer and he won the Queen's Vase eight times.
The full race title will be 'The Queen's Vase In Memory of Sir Henry Cecil'.
Along with the Gold Cup and the Royal Hunt Cup, the Queen's Vase is one of three races at Royal Ascot for which the Queen donates her own trophy.
Jockeys in the race will wear black armbands, while a minute's silence will be held before racing on Tuesday.
"Sir Henry was an intrinsic part of Royal Ascot with 75 winners over more than four decades," said Johnny Weatherby, Her Majesty's Representative at Ascot.
"It is no secret that Royal Ascot was his favourite meeting of the year and we felt it was fitting to honour his achievements here next week, and remember the passing of one the greatest figures that the world of sport has ever seen.
"Our thoughts are with Sir Henry's family and I am delighted that Lady Jane will be accompanying the Countess of Wessex for the trophy presentation following the Queen's Vase."
