OTT Ultra Marathon

The OTT Ultra Marathon is a challenging 30-mile trail race set in the scenic Brecon Beacons, South Wales. Starting in Merthyr Tydfil, the course follows the Taff Trail and riverside paths before ascending to Pen y Fan, the highest peak in South Wales at 886 meters. Runners then descend via Jacobs Ladder and traverse forestry tracks alongside reservoirs, offering stunning valley views, before returning through the Taff Fechan Nature Reserve to the finish.

The route is technical yet runnable, featuring five checkpoints with aid stations. The event suits both those stepping up to ultra distances and experienced ultra runners, emphasizing self-sufficiency with mandatory kit requirements. Visit the organization's website for the most recent information.
