The Union Cycliste Internationale (UCI) is pleased to announce that Vittoria Bussi (BJ Bike Club ASD) again broke the UCI Hour Record presented by Tissot by covering a distance of 50.455 kilometres today on the Velodromo Bicentenario in Aguascalientes, Mexico. She set the new mark after abandoning an attempt just over the half-way mark the previous day.
The Italian thus betters her own record that she established when she became the first woman to break the 50km barrier by covering 50.267 kilometres on the same velodrome in Aguascalientes on 13 October 2023. She had previously held the record for three years – from September 2018 to September 2021 – with a distance of 48.007 kilometres.
The 38-year-old mathematician is a former middle-distance track runner, who took up cycling at the age of 27. She has podiumed several times in the individual time trial at the Italian National Championships, and was part of the Italian team that took the bronze medal in the team time trial mixed relay at the 2020 UEC European Championships. The following year, she won the opening time trial of the Czech stage race Tour de Feminin – O cenu Českého Švýcarska.
Vittoria Bussi will shortly attempt another world record in Aguascalientes: that of the women's 4km individual. Great Britain’s Anna Morris holds the current record of 4:24.060 which she set at the Lloyds National Track Championships in Manchester, Great Britain, on 22 February 2025. The record has been lowered several times since the introduction of the new individual pursuit distance for women – increased from 3km to 4km – on 1st January this year.
Vittoria Bussi said: "I can say with a smile that I contributed to the history of the UCI Hour Record for women. This record has always been really special to me as an athlete and as a person, and I hope I have transmitted to young generations and people that sport is not just an athletic performance but that athletes bring messages to the world. The Hour taught me that one of the most important things in life is to understand the preciousness of time in every single instant of our life."
