Dyfi X ULTRA

This was held for the first time in 2024, and details of the course have not yet been released.

NOT IN 2026

This event is a monster, at 60km (that's sixty kilometres), and is one of the longest swimrun events on the planet. It will be challenging, but also extremely rewarding!

We will add more information on the ULTRA distance event as it becomes available.

In the early part of the main European season - May - Weswimrun holds a training workshop to introduce the basics of swimrun and help get you up to speed with the sport. While the essential gear is covered - wetsuits, paddles, pullbuoys, shoes and socks - there is much more! The team also run you through useful topics such as how to 'read' a course, how to use a tow-rope or tether efficiently, event strategy, and safety.

The physical sessions involve some swimming and running, but only for short sections; the emphasis is on the transitions from run to swim and from swim to run. This is perhaps the most important part of the course.

The 2025 dates were 10th May for the Liverpool workshop, and 26th May for the Wales workshop.
