During the under-23 race at the 2018 European Cross Country Championships, Emile Cairess fell over at half-mile stage but managed to move up 59 places for eighth position and a team silver medal.[4]
In January 2022 at the Valencia Ibercaja, he tied Mo Farah's over 10-year-old British 10 kilometres record with his time of 27:44.[5][6] The 24-year-old set five other personal bests that year (3000 m, 5000 m, 10,000 m, 5 km, half marathon).[2] At the European Cross Country Championships held in Turin, Italy in December, Cairess achieved his best performance up to that point, with silver medal in the men's senior race behind only reigning world 5000 m champion and European record holder in the event Jakob Ingebrigtsen.[7][8]
On 4 March 2023, Cairess broke Richard Nerurkar's 30-year European 10-mile record (46:02) with a time of 45:57 at the 'Breaking 10' in Barrowford.[9][10] Later that year, he finished sixth on debut in the London Marathon in a time of 02:08:07.[11]
