No reviews of the MTC Afanc, and nothing on what people wore. Both are things no organiser publishes and every runner wants before they enter — how it actually went, and what was on your feet.

What you’re in for
Glasbury to Merthyr Tydfil, 40 miles up the Usk through Brecon and over the Beacons on the Taff Trail, on day five of the Wales end to end. National Cycle Route 8 the whole way. Glasbury to Merthyr Tydfil: 64.0km, with six checkpoints on the way. It is day 5 of the Wales end to end, and you can run it on its own or as part of the whole. The crossing of the Brecon Beacons is the high point of the Welsh series in every sense — the Taff Trail climbs past Talybont and the reservoirs to the pass, then drops into the valleys. Mount to Coast rules apply on the single day as on the series: preset cut-offs based on a minimum 4 mph average, a warning the first time you fall below it, and no one on the course after ten at night. Checkpoints roughly every eight miles, a tracker with an SOS button, and maps and GPX for entrants only — bring a map case.
Terrain and trail
National Cycle Route 8 — Lôn Las Cymru — the whole way, which means traffic-free cycle path, old railway and quiet lane, hard-surfaced almost throughout. Road shoes, as the organiser supplies. The difficulty is the distance and the hills of mid-Wales, not the ground.
