Red Bull Timelaps

Red Bull Timelaps challenges cyclists to compete in the world’s longest one-day road cycling event.

As summer fades to winter, teams of four will race through the night on the weekend the clocks go back in the UK, making it a gruelling 25-hour race against time. In a twist, at 0200 a ‘Power Hour' is activated; and riders shift to a shorter course where laps count double.
