Routes, logistics and requirements
The 100 mile is an out-and-back traverse between Hay-on-Wye and Pontneddfechan, crossing 44 summits. The 50 mile and 50 km run south-north across the Bannau Brycheiniog range; the 21 mile starts at Llangynidir and follows a high ridgeline back toward Hay-on-Wye. Checkpoint numbers are: 13 for the 100, 6 for the 50, 4 for the Ultra Bach, and 3 for the trail race. Drop bag provision is available (two for the 100, one for the 50).
Navigation: the 50 mile, 50 km and trail races are marked at major junctions and rely on a GPS trace plus markers and map or compass. The 100 mile route is unmarked for the first half and requires following the published GPS trace. A compulsory kit list applies and mountain experience is required; entry to the 100 mile requires prior completion of a similar mountain 50 mile event. Coach transport options are provided between finish and start locations, and a Sunday return coach option is available. Visit the organization's website for the most recent information.
