Alex Dowsett (Israel Startup Nation) will attempt to recapture the world hour record in Mexico on November 3.

Dowsett, a Briton with Israel Startup Nation, is the seventh challenger since the UCI unified the hour record classifications in 2014 and held the record for a month in 2015. His distance of 52.937 km was surpassed by Bradley Wiggins. The current record is 55.089 km held by Victor Campenaerts.

Dowsett will attempt the high altitude run at the Velodromo Vicentenario in Aguascalientes.

"When I took the record in 2015, I ran well enough to break it, but I thought I had more room at the end.

"My attempt last year was derailed when I signed with COVID-19, but I have all the same reasons for wanting to set the record. I want to see how good I am, I really love this competition, and I'm honored to be able to try again.

"In terms of difficulty, I know that Victor has set the bar very high. It will be a very big challenge, but I think I have the potential. The biggest hurdle will be the elevation, as the event will be held in Mexico.

"The higher the altitude, the thinner the air, so the output required will be lower than at sea level, but the thinner the air, the harsher the breathing environment, so it won't be smooth sailing. Ultimately, we believe that being at high altitude should be more beneficial than detrimental."[13

Dowsett was scheduled to challenge Manchester last December, but was forced to postpone after contracting COVID-19 in mid-November. This year, the 33-year-old Dowsett completed his second season with the Israeli Startup Nation, helping them to a time trial victory at Settimana Coppi e Bartali. His new challenge is part of a renewed interest in hour records: at the end of September, Jocelyn Roden broke the women's record with 48.405 km, and Dan Bigum broke the national record in Wiggins with 54.723 km. Time trial world champion Filippo Ganna has also expressed interest in a 2022 attempt.
