You're quite correct Daniboy - the loop is just about 13 miles - the balance will be taken up with a section within the Sports Ground - that's why we are waiting for conformation from the measurer. Very few tree roots - all bar around 1.5k of the loop is on tarmac roads. One small section is on the Pilgrims Way - but it was in decent condition the last time we were there about three weeks ago.
Sorry chaps - have only just seen this forum! Rick you are correct that we are using a combination of the Ashford and Charing 10k courses.
We can't publish it just yet until the course measurement has been approved. If you'd like to know the proposed route, email us at email@example.com and I'll send you a copy of the provisional course map. Once the measurement is 'signed off' we will publish the route online..
