East Devon 8 and 5 Trigs

So, what’s involved?

We’ll be taking a break in 2024, but this will return in 2025 with a few changes.

  • 33 and 21 mile (53km /34km) options
  • Self navigate
  • Pairs or teams
  • Solo entries available for confident navigators
  • Open to runners and walkers
Trigpoints are the common name for “triangulation pillars”. These are concrete pillars, about 4′ tall, which were used by the Ordnance Survey in order to determine the exact shape of the country. They are generally located on the highest bit of ground in the area, so that there is a direct line of sight from one to the next. By sitting a theodolite (an accurate protractor built into a telescope) on the top of the pillar, accurate angles between pairs of nearby trigpoints could be measured. This process is called “triangulation”.

Our Event

Eight of these trig points sit on a beautifully varied trail loop in East Devon. The route starts on Budleigh Salterton seafront and follows the South West Coast Path to West Down Beacon. Far reaching views from here extend to Berry Head, Portland and Dartmoor. From here, both 5 and 8 Trig routes head inland and cross Woodbury Common, passing 3 trigs on the way. The routes split at Harpford with the 5 Trigs route crossing Mutter’s Moor and on to High Peak. The 8 Trigs route continues to Harford Common and the Sid Valley, before reaching the South West Coast Path again at Weston Cliff. The route climbs multiple hills as is passes through Sidmouth before joining the 5 Trigs at High Peak. A stunning section of coastline with rolling hills leads back to Budleigh Salterton.

The Route

All trig points can be found without the need for complicated navigation techniques. However, a basic understanding of navigation will be required as the 8 trigs route isn’t way marked. Total distance is approximately 33 miles.
The shorter 5 trigs route avoids the biggest hills on the Eastern part of the course. A total distance of just over 21 miles.
Both routes will be available on Outdoor Active and a GPX file can be downloaded. If you prefer a traditional map, Explorer 115 (Exmouth and Sidmouth) covers the whole route. This is our recommended route, but the exact line you take is up to you! (Please see notes in participant handbook).
