Extra places will be available for the Tour of Cambridgeshire Chrono time trial on June 4 2016, part of the Tour of Cambridgeshire Gran Fondo weekend.
After negotiating with the local authorities, the organiser is now able to offer a place in the time trial to everyone who has pre-registered, plus there are extra spaces available across all categories.
In addition, a new under-19 age group category has been introduced where younger riders are able to take on the same closed roads 26.5-kilometre course.
The Chrono features an indoor start ramp, commentary and electronic timing, which coupled with the closed roads make for a 'professional' race experience.
Riders are set off at 30-second intervals. Those achieving a time in the top 25 per cent of their category (age/gender) will be entered into the 2016 UCI Gran Fondo World Championships.
