Why this course needs its own plan

One climb, then a very different second half

Most UK ultras spread the terrain evenly. Brecon to Cardiff front-loads its only real climb, then hands you nearly 30 miles of progressively flatter, harder-underfoot running — a pacing puzzle that generic ultra advice doesn’t cover.

A point-to-point with real logistics to plan

Coach transfers, a halfway drop bag, a 14-hour cutoff and a likely finish after dark in February. Get the logistics wrong and you’re stressed before the start line.

Built by a certified ultra coach

Written by a UESCA-certified ultrarunning coach, using the organiser’s own course notes — not generic advice adapted from a different race.

A training shape you can use today

A 16-week framework you can follow as-is or use to sanity-check a plan you’re already running.
