Entry costs £80. The finish location and event base is at Coleg y Cymoedd, Parc Nantgarw, Nantgarw, CF15 7QX.

Route and logistics
The route follows the Taff Trail from Brecon to Nantgarw. The first 30 km are almost exclusively on footpaths and forestry trails; from Merthyr the course follows an off-road cycle path to the finish. The route passes the Monmouthshire & Brecon Canal to Talybont-on-Usk, climbs to Torpantau, then descends toward Pontsticill Reservoir, Merthyr (with views of Cefn Coed Viaduct and Cyfarthfa Castle), Aberfan memorial, Pontypridd and Nantgarw. Because the course is linear, competitors park at the finish and are transported by coach to the start. The event base offers parking, a café, a large indoor registration area, toilets, changing rooms and showers. The venue is accessible from the A470 and is one junction off the M4, with local bus and rail links to Cardiff. Visit the organization's website for the most recent information.
