Course Details

The trails go deep and steep. Down to the depths of the Teign River valley, then rising above the Fingle treeline. Two extremely tough Woodland Trail Races.


Follow the red lines and arrows crossing the iron bridge over the River Teign to the aid station at Fingle Bridge. The blue lines and arrows are the route to the finish after crossing Fingle Bridge, with some technical sections before turning right for home.

Peanuts, jaffa cakes, jellied sweets and water provided at mile 3 aid station at Fingle Bridge.

Total ascent: 289m.

Half Marathon:

Follow the red lines and arrows to the aid station at Fingle Bridge and turn up onto a long hill before turning left and keeping high in the woods until a sharp left turn takes you down to the river. The longest climb is next, from the River Teign up to the highest point of the course and to the second aid station at Hillfort carpark (mile 7.5). Now for the longest descent, back down to the river. Mile 9 sees the steepest climb of the day back to a crossroads. From here, the blue lines and arrows show the way to the finish and you repeat a section completed earlier in the race, but you benefit again with another long down and along the river to Fingle Bridge aid station at mile 11. Crossing over the bridge to follow the river, with some technical trails before turning right and back up to the finish.

Features a whopping 871m ascent, but 7 miles have a positive ascent and the other 7 have more descent than ascent. Plenty of tough hills but the benefit comes with an equal downhill.

Aid station at Fingle Bridge at mile 3 gives peanuts, biscuits, jellied sweets, water, coke etc. More will be available at mile 7.5 (Hillfort car park), and at mile 11 back at Fingle Bridge for the final leg.

    Did the Half Marathon in 2019

    Wow! How can one race have so many hills in.....both up and down!! This is tough in a weirdly good way. Lovely trails to run on through the woods and along the river. Very well marked and marshalled. Great medal as per usual with PureTrail!

    Did the Half Marathon in 2019

    This race was probably the hardest race I’ve ever ran but it was so enjoyable ! The race is so well organised and everyone is fabulous

    Did the Half Marathon in 2019

    I love this race, the location is as beautiful as it is demanding. Each Puretrail event is superbly organised and those organisers are meticulous to every little detail being runners themselves.
    You’ll be challenged in any Puretrail Race and you’ll earn that medal as none of their events are easy.
    Each event is a great experience in beautiful, natural surroundings and all superbly marshalled by avid trail runners eagerly spurring you on. 10/10

    Beautiful course, with a fair few hills! PureTrail always do great bling - lovely medal. I like that you have to bring your own cups to events but I do think PureTrail's events are quite expensive for what you get.
  • Did the 10K in 2019

    This is an area I’ve always wanted to run so I was determined to take part this year and it was as fantastic as I expected. Incredibly beautiful countryside and views. Highly recommend it!
  • Did the 10K in 2019

    This was my first trail race and it didn’t disappoint. I ran with my brother and some friends and my goal was simply to enjoy the run. The views were breathtaking, Dartmoor is such a beautiful part of the country. I really enjoyed the challenge of the terrain, and I can see us returning to trail events soon. The organisers and team were really friendly and it’s easy to see how they’ve built such a passionate community around their events.
  • Did the Half Marathon in 2019

    Im fairly new to this area so still getting used to the beautiful places on my doorstep, but I thought this venue was particularly stunning! Also I may not have visited it if the race hadnt drawn me there. There were several light-hearted moans about the hills and how tough the course was, but I am used to mountains so that didnt impact on me, I just thoroughly loved it! The PureTrail lot are a great bunch too, I have been running with them on their Wednesday night outings which are free!!
  • Did the 10K in 2019

    First attempt at a trail race and loved it! Genuinely loved the community feel of this event and had great fun speaking to everyone doing the race and the organisers. Tough hill makes the finishline all the sweeter :) Definitely want to go back next year - made a great weekend away.
  • Did the Half Marathon in 2019

    My 3rd trail run/race. Great venue. It was a tough and fun 14 mile run. Good organisation although at the 10k/14 mile bridge division the marking/steward could have been clearer as I ended up adding a further half mile to my run because I followed the 10k route before realising my mistake. I would recommend the run.
  • Did the Half Marathon in 2019

    This was my first Pure Trail event and I loved it! I am a slower runner but really enjoy trail running. The course was amazing if not hard (but I didn't expect anything different) especially the cruel 'hill' at the finish line. The marshalls were very encouraging too. As always there weren't many people at the finish line by the time I came in but I'm getting used to that. The organisers who were there did cheer me over the line which was gratefully appreciated. Put it this way - I enjoyed it so much that I have now signed up for the next race - Race the Tide! See you there.
