Route description

The race starts by flowing downhill through Menai Bridge town centre and along the winding closed roads to Beaumaris.

Menai Bridge
Connecting Anglesey and mainland Wales.

Pass the famous and near-perfect Beaumaris Castle then head up towards Llanfaes and complete a small loop before returning the way you came, taking in the breathtaking views of Snowdonia, to finish in Menai Bridge.

This partially closed road course is a stunning showcase of some of North Wales' most beautiful scenery.

Cut-off time

In the interest of athlete safety and the safety of volunteers on the course there will be strict cut-off times in place. A confirmation of specific cut-off times will be detailed in your Final Instructions which will be available on the website 10 days prior to the race.

Runners arriving at Gallows Point (approx. mile 10) more than 2½ hours after the race start time will not be permitted to continue in the race. There will be a shuttle vehicle available to collect those who have not made the cut-off.

If you are still taking part in the race when the road re-opens, you will be asked to move to the pavement for your own safety.

Finish line timing will finish at 13:00.

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
