Jones o Gymru Anglesey Half Marathon and 10k 2027
The stunning Jones o Gymru Anglesey Half Marathon & 10km – The most beautiful closed road half marathon in North Wales!
With an exciting event village located at the Mona Showground, right in the heart of Anglesey, the races now feature fully closed-road routes for both the 10K and the Half Marathon. Expect the same wonderful Eryri views, but now delivered through two fully closed-road courses.
The Jones o Gymru Half Marathon and 10K remain perfect for all abilities, with hundreds of first-timers, fundraisers and seasoned runners lining up together at the start. Providing an ideal mid-point for marathon preparation, this beautiful undulating course, now completely traffic-free, offers the perfect chance for an early-season personal best.
This great event also includes the Dragons Dash Kids’ 1.3-mile race, open to children as young as 5, ensuring that there truly is something for everyone!

"Loved the Slate and Mug as mementos. So much more useful and environmentally friendly than a medal. This was my first Anglesey Half Marathon, and it's gone straight into my top 5. Beautiful course and exceptional organisation. All in all, a fantastic race experience!"
