The course

Course line from the race's own GPX. Source file. Recorded 2026.

Out of the Bannau Brycheiniog and through the South Wales Valleys to the finish in Bute Park, next to Cardiff Castle.

The race

What this one is

Six days, 380 km, 16,400 m of ascent from Conwy Castle to Cardiff Castle, run as six daily stages with tented overnight camps and a 22:00 course closure each day.

Inspired by the 1992 race. The six-day Conwy to Cardiff format was announced in August 2020 and first raced in 2021; earlier editions were five days. Ourea Events went into administration in 2026 and Ultra X took the event over.

Ultras change. We will tell you when this one does.

Cutoffs move, races get postponed, lotteries open and close. We read the race's own sources and record where every fact came from. Put your email in and we will send you what changed, and where we read it.

No account, and nothing to cancel.

What happens to your email. Nothing else. I do not sell it, and I will not send you anything except this race changing. One click gets you out.

I keep this catalog because the information is scattered and hard to trust. Telling you when it moves is the same job.
