Rooster Booster was a gelding whose grey coat (inherited from his dam Came Cottage[1]) and racing style made him easily recognisable.

[2] He was originally trained by his owner Norman Richard Mitchell in Dorset but had his biggest successes after he was bought by Terry Warner in 2000 and sent to the stable of Philip Hobbs at Withycombe in Somerset.

[3] He was then switched to the yard of Philip Hobbs and made his debut for him in April 2000, finishing 2nd behind Valiramix in a Novices' Hurdle at Chepstow.

He led over the last but was caught in the closing stages and beaten a head by the Edward O'Grady-trained Sacundai after Johnson dropped his whip on the run to the finish.

On 20 December 2005, Rooster Booster collapsed during a routine training session in preparation for a run in the Christmas Hurdle and died from heart failure.

The Independent described him as one of racing's "most cherished champions",[8] while his regular jockey Richard Johnson said, "He gave great pleasure not only to myself but to the owner and to everyone connected with him".
