Good luck to you both with that Dave.
A friend of mine has set the route for this years Chagford Challenge.

Might be right up your street if you fancy a visit to the West Country.
That does sound interesting Buzy, thanks.
My wife and I are really keen to spend a week in Cornwall (hopefully around September). We binge-watched the whole of Poldark and loved the landscape. Then, by coincidence, we discovered that a YouTube channel we follow (Run4Adventure with Loyd Purvis) is based in the same area and it looks an amazing place to do some trail-runs.
For a moment, I wondered if Chagford might be somewhere in the west of Cornwall, but sadly it's a long way away. Oh well, I'm sure we'll come back to Dartmoor before too long - thanks for the thought.
