Active autumn

Cardiff Half Marathon

Autumn is an enjoyable time to get outdoors. It's the time of year the popular Cardiff Half Marathon takes place. You can take a walk and see the changing colours of the trees. We’ve many wooded areas and forests such as Clocaenog Forest in West Denbighshire/Conwy and Tintern Forest in the Wye Valley. You may catch wildlife getting ready for the winter.

Walking festivals

Walking festivals during the season include the Corwen Walking Festival in September, which takes place in the Clwydian and Dee Valley Area of Outstanding Natural Beauty. 

The Snowdonia Walking Festival offers a number of guided walks by local experts with many years experience and knowledge of the forests, lakes and mountains that encircle the village.

Runs and triathlons

For the more competitive Ironman Wales takes place in September in Pembrokeshire. Competitors start from the beautiful seaside town of Tenby and face a 2.4 mile swim, followed by a 112 bike ride and a 26.2 mile run. Also in September, the Sandman Triathlon takes place in Anglesey. 

Others will compete in the Rat Race Man versus Mountain and the Ring O Fire 135 Ultra Marathon in beautiful north Wales.

The Tydfilians’ Roman Run covers the route marched by the Roman Legions travelling between forts in Brecon and Merthyr Tydfil. This run has been held every year since 1980 – making it older than the London Marathon. This 16 mile run is said to be one of the toughest runs in the country and features stunning scenery.  

The Cardiff Half Marathon is an annual autumn event, which takes place on each October. The first event took place back in 2003 and is now the UK’s second largest half marathon. It is also Wales’ largest road race and Wales’ largest multi-charity fundraising event.
