Sid Valley Ring Half and Third Marathon | Third Marathon

This was a joint venture between Sidmouth Town Council and the Sid Vale Association. A donation from your entry fee will go towards the maintenance of this trail. With an “uphill start”, the route takes you through quiet country lanes and footpaths and climbs to a height of 236m, before dropping down into the pretty village of Sidbury. Another section of back lanes lead to the tiny hamlet of Harcombe, the “Valley of Hares”, just before a steep climb towards Dunscombe cliffs and the coast path. Stunning views along here across Lyme Bay, stretching as far as Portland and Berry Head. A short excursion inland takes you through the picturesque village of Salcombe Regis, a woodland section, and back to the coast path. The views on the final downhill section to Sidmouth are incredible! **New for 2026 – The Sid Valley Ring Third Marathon. This will follow the River Sid upstream to Sidford, before joining the Half Marathon route near Harcombe (13.5km).**
