The 1905 Derby excited particular interest locally because it was won by a local horse, Cicero, who had been bred by Lord Rosebery at his stables at The Durdans in Epsom. Cicero was the favourite of the nine runners at 11-4, but the French colt, Jardy was also a hot tip although a cough had affected his form. It was neck and neck between the two horses in the final straits of the race but Cicero responded to the cheers of the crowd as well as the urging of his American jockey, Danny Maher, to win the race by three parts of a length. He set a new course record of 2 minutes 39 2/5 seconds.
The subsequent celebrations covered a period of weeks, starting with a firework display in the grounds of The Durdans carried out by the famous firework company, Messrs Brock and Co. All sorts of pyrotechnic novelties enthralled the large crowd for nearly an hour, with a remarkable set piece that spelt "Well Run 2 mins 39 2.5 secs". The evening concluded with a rousing "Three cheers for Lord Rosebery".
Lord Rosebery also provided a lavish treat for the inmates of Epsom workhouse in Dorking Road on Thursday 22 June 1905. There were over 400 inhabitants at this time ranging in age from 3 weeks to 92 years. The weather was perfect and every effort had been made to ensure that they all had a day to remember. The workhouse dining hall had been decorated with primrose and rose drapery, Lord Rosebery's racing colours, and the stage had been covered with plants and two large portraits. The following Thursday Lord Rosebery held a grand celebratory garden party to which he invited all the working men in Epsom and their wives, a total of over 3000 guests. Unfortunately just as the event was due to start the weather broke and there was a violent thunder storm with lightning and torrential rain. The guests were caught unprepared but large marquees had been hired from GS Waglan in Epsom in which they could take shelter. The storm lasted for over an hour, but the programme of entertainment continued valiantly with music provided by Mr Glenister, the Band of the Coldstream Guards and the Epsom Town Band. Tea was taken in three sessions in the marquee.
