A chance to ride the little-used but fast F2a/25 course just West of Cambridge. The 25 is a two-lap version of the same bit of the A428 dual-carriageway that is used by the fast F2a/10. F2D/10 and F2/15 courses, running between Caxton Gibbet roundabout in the west and Madingley interchange in the east. The road is flat and the surface good. The event will be run to the usual high standards of Cambridge CC with excellent signage, plenty of marshals and home-made cakes.
