The same iconic races, just a little more Welsh (Cymraeg). In 2027, Ultra-Trail Snowdonia has become Eryri by UTMB. In 2022, Snowdonia National Park reverted to the historic Welsh name of Eryri. UTMB is proud to be following in this tradition by renaming the iconic Ultra-Trail Snowdonia.

Starting on Friday, UTS 100M is the ultimate grand-tour of Eryri (Snowdonia), Wales' largest National Park. It really is 'Beautiful beyond belief. Savage beyond reason'.

Eryri 100M

Starting on early Saturday morning, Eryri 100K covers the highlights of the mountainous areas of northern Eryri (Snowdonia), taking in countless stunning trails, technical ridges and epic views.

Eryri 100K

New for 2026, Eryri 80K takes runners from the sea in Caernarfon at sunset, into the mountains of Eryri for a race into the darkness.

Eryri 80K

Eryri 50K is the perfect stepping stone into Alpine-scale mountain ultrarunning, taking in several technical mountain trails around the Yr Wyddfa (Snowdon) massif. Not to be underestimated, this remains a significant challenge.

Eryri 50K

The Eryri 25K is inspired by Eryri (pronounced Eh-ruh-ree) itself: the 'land of the eagles', that once soared freely, above the snow-capped peaks of this mythical land.

ERYRI 25K

More than 60 nationalities and over 2,800 runners took on the four race distances across the rugged wilderness of North Wales at Eryri by UTMB in 2026. See the full results of this epic eighth edition.
