Harlech Duathlon 2021

Under the castle's watchful eye, the Harlech Sprint Duathlon is one of the best loved races on the calendar for those who don't like to get wet.

With a stunning cycle sandwiched between two short runs, it's perfect for beginners and a great season opener for the more competitive.

Harlech is a small town with a big heart and this duathlon represents it perfectly!

We're very excited to announce this will be the Welsh National Duathlon Championship!

This event is an Always Aim High Community Event. Profits from our Community Events go towards supporting amazing local projects and community groups like Harlech Triathlon Club, local Community Councils, local Mountain Rescue teams including South Snowdonia Mountain Rescue, Ogwen, Aberglaslyn and Llanberis MRTs, along with many more community projects.
