Road Cycling
Carmarthenshire drew international attention when it hosted the 2018 Tour of Britain Grand Depart and the Grand Finale of the 2019 OVO Energy Women’s Tour. The tour of Britain returned in September 2021 with the exciting team time trial taking 18 of the best teams through the picturesque Tywi Valley to finish at the National Botanic Garden of Wales.
Today the same lanes and landscapes tempt leisure cyclists and endurance riders to explore for themselves. Whether you’re looking for a gentle leg-stretch or a long, testing day, a romantic ride for two or a multi-day adventure for your club, Carmarthenshire is your perfect cycling destination.
Here are 23 great road routes for confident cyclists after a challenge, with distances ranging from 10 miles to 65 miles, covering coastal paths, countryside lanes and bustling market towns.
