About Southern Grit 2027
Southern Grit is a one-day, self-supported gravel sportive organised by Hidden Tracks Cycling, starting and finishing at Herne Hill Velodrome in south London.
Taking riders out of the capital and into the Surrey Hills and North Downs, the event combines woodland trails, gravel tracks, bridleways, chalky climbs and stretches of tarmac. The routes offer a challenging mix of off-road riding and climbing, with two distances of 100 km and 110 km.
Southern Grit is a non-competitive event. Riders follow GPX routes independently, with individual GPS trackers providing live location tracking and finish times.
The event includes pre-ride refreshments, a halfway feed station and food and drink at the finish.
