Altra Anglesey Trail Half Marathon & 10K 2024
Sister event of the Jones o Gymru Anglesey Half Marathon, the Altra Anglesey Trail Half Marathon & 10km is set in the beautiful surroundings of Newborough Forest, Anglesey.
The course takes you through the trees onto the stunning Llanddwyn Island and onwards to beautiful winding woodland trails which once hosted the Commonwealth Mountain and Ultra Distance Running Championships. You’ll catch glimpses of the Llyn Peninsula and the mountains of Eryri (Snowdonia) amongst other incredible views. With loads of single track forest trails, quiet forest views and sandy running trails, there is something for everyone in this race whether you're an experienced runner, first timer or you’re more familiar with road running.
This was a SOLD OUT event for 2023, so make sure you get your entries in quick!
