The start is just across the road on the A26. From the start you ride a short distance before filtering left down the slip ramp (known as the ski slope) onto the A21, heading towards Sevenoaks.
You follow the road for over 5 miles and take the next slip ramp up to Sevenoaks Weald roundabout. Here you go all the way round and retrace back down the A21. You finish at the big road sign and speed camera, (basically where the yellow road goes under the A21/Manor farm is indicated on the map) . Once past the finish timers/line, continue onwards up the slip ramp and back up the hill to the layby.
Park in the layby on the A26 heading southbound towards Southborough. See pointer HERE!
(post code takes you past the layby when heading south towards Southborough)
