Marcin Bialoblocki (NOPINZ) took a huge chunk off the 25-mile national competition record with a new benchmark of 42 minutes and 58 seconds, while Zach Bridges (Ribble Cycles) clocked 47-27 to break the junior record and Alice Lethbridge (Drag2Zero) won the women’s event.

“Last year when I set the 43 minute time [that was subsequently disqualified] the conditions were much better,” said Bialoblocki. “I also got held up at one of the roundabouts this year and lost some time.

“But I’m happy especially with my power for the 43 minutes of effort, I’m very happy to set the time I did.”
