The route for the race is a gently undulating mixture of residential and rural sections, taking in the villages of Hertingfordbury, Birch Green and Cole Green, plus a 4 mile section along the traffic-free Cole Green Way pathway.
The race will also start and finish on Gosling Running Track, a great spectator location!
