Event overview

For 2026, the event enters an exciting new era with the venue moving to the Anglesey Showground, right in the heart of Anglesey, now featuring fully closed-road routes for both the 10K and the Half Marathon. Expect the same wonderful Eryri views, but now delivered through two brand-new, 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!

Anglesey Showground is located in Mona, Anglesey, just a couple of minutes from junction 6 of the A55, and 10 minutes from the mainland and the city of Bangor.

Truly fantastic race! I will definitely be back - the start line is fantastic, the views throughout are spectacular and a massive thanks must go to the locals who came out in force ringing their cowbells to support every runner.

 This was a lovely race. Well organised with good pre event info. Amanda C

This was my first half marathon. Runners of all types. The hilly bits are not too bad actually, was a bit scared but by the time I got there, the spirit of the experienced runners lifts you through. Tuheen H

Brilliant, gorgeous and unique race with awesome start location and so much support along the way. Ali L

This was without doubt the most picturesque 10k I've done to date. Running down underneath the bridge was amazing. Clive P

It's my 6th visit to the Anglesey Half Marathon. And it still remains my favourite road race. Si F

This was my first road race. It was a fantastic event and one that I will never forget Gemma D

I thoroughly enjoyed the Anglesey Half Marathon. The scenic, undulating course started promptly, no messing, straight into the race. The support, be it marshals, supporters and participants were all great sports! San B

Train slow

Low-intensity training is easier for you, reduces the risk of injury and helps builds an efficient aerobic system.

Eat natural

Cut out sugar & junk food, reduce carbs, eat natural foods and train your body to burn fat for fuel.

Get outdoors

Fresh air, natural light and reconnecting with nature all help to improve mental and physical wellbeing.
