Vittoria Bussi regained the UCI time record at Velodromo Bicentenario in Aguascalientes, Mexico, and achieved her goal of becoming the first woman to break the 50km mark.

Bush covered 50.267 km, adding more than a kilometer to the previous record held by Ellen van Dijk, setting the distance to beat at 49.254 km in May of last year.

"I am excited to break the UCI time record timed by Tissot for the second time in my career, covering a distance of 50.267 kilometers in the same velodrome that I previously broke it in 2018," Bush said in a UCI statement.

"I owe this to everyone who believes in me and my project and has supported me over the years. This achievement is the result of excellent teamwork and I would like to thank everyone who contributed to make it happen.

The 36-year-old professional cyclist with a doctorate in pure mathematics from the University of Oxford won the top spot from 2018-9 to 2021-9 at a distance of 48.007 km. British rider Justine Lowden topped it with an effort of 48.405 km, while Van Dijk pushed the record to a much higher 49.254 km.

The previous 2 records were set in Switzerland, but Bussi was turning to crowdfunding to support the attempt in Aguascalientes, Mexico. The rider exceeded the goal of 10,000 euros and hit 12,064 euros.

"As a mathematician, I contribute to the research of aerodynamics and technology and aim to break the 50km mark on my next attempt at the Women's UCI Hour record," she explained during the build-up.

The attempt was originally scheduled for Wednesday, 10/11, but instead took place on Friday, 10/13, as the conditions and speed of the track were lower than ideal due to the sudden drop in temperature in the weather.

Bush's latest record is the 7th new record since the modernization of UCI time record regulations in 2014, with Molly Shaffer Van Houweling, Bridie O'Donnell and Evelyn Stevens also contributing to pushing the mark higher.
