Drivers are being advised to avoid the Half Marathon route between 8.30am and 2.30pm as many of the roads will be closed or will have restricted access to traffic.
The scenic route will take runners out of Tonbridge along Brook Street, Molescroft Way, Upper Hayesden Lane and Ensfield Road to Leigh.
There they will turn right and head through the village towards Hildenborough before turning left into Watts Cross Road (Rings Hill) and then left again at every junction until the route arrives back in Leigh village centre via the B2027.
It’s then a right turn into Ensfield Road for the return leg. When they reach Hayesden Lane, runners will turn left and then left again into the narrow Lower Hayesden Lane, which leads back to Brook Street and the 300m sprint to the finish.
The race village at West Kent College will be open for competitors to register and collect numbers, etc, from 8.30am.
