The Lab Field Test #001: The Fence

THE LAB FIELD TEST #001: THE FENCE Follow the line, not the path. Sunday 11 October 2026 £125 per person | 6 places only | Full-day mountain field test THE IDEA One day. One line. Where there's fence, we follow the fence. Where the fence disappears, we follow the boundary stones. The only deliberate deviation is Arenig Fach. The Migneint is one of the biggest, wettest and least forgiving upland areas in North Wales. It doesn't behave like the famous parts of Eryri. There are no clean ridges, no obvious rewards and no tidy summit-to-summit rhythm. Its pull is stranger than that. Space. Bog. Fence. Stones. Silence. Slow movement across ground that refuses to make things easy. THE GROUND Expect around 20km with 700-900m of ascent, depending on final access and vehicle logistics. On paper, that sounds manageable. On the ground, it's different. Wet, rough, uneven, pathless upland. Bog, tussock, peat, awkward crossings, boundary posts and slow progress. This is a long linear day with vehicle logistics at either end. Expect around 9-10 hours on the hill. You'll need solid hill fitness, resilience on rough ground and a willingness to spend a full day moving steadily through awkward terrain. This isn't for anyone chasing fast progress, famous views or clean paths. The line itself is the point. WHAT'S INCLUDED • Professional mountain leadership by Jacob from Mountain Craft • Route planning and on-the-day judgement • Vehicle logistics for the point-to-point crossing • Emergency satellite communication • Small-group Lab field test (maximum 6) WHAT'S NOT INCLUDED • Personal walking kit • Food and drink • Transport to the meeting point • Dry feet • An easy line across the Migneint PLEASE NOTE The Fence isn't hard because of the numbers. It's hard because of the ground.
