Some tough climbs on the Lôn Las Cymru route.

Cycling Lôn Las Cymru: A Spectacular 4-Day Adventure through Wales

Bike the UK for MS ventured into the heart of Wales with the inaugural Lôn Las Cymru ride in May. This challenging yet rewarding route covers approximately 250 miles (400 km) from the picturesque town of Holyhead to the vibrant cities of Cardiff. The ride not only offered scenic landscapes, but also served a higher purpose, raising funds and awareness for multiple sclerosis (MS). Let’s dive into the unforgettable experience of the cycling Lôn Las Cymru in 2023 and explore the renowned route to inspire your next adventure.

The 2023 Lôn Las Cymru Ride

The 2023 team was composed of 11 exceptional Bike the UK for MS alumni, individuals who had previously embarked on trips such as Land’s End to John O’Groats, the North Coast 500 and the Sea to Sea with the organisation. Supported by 5 route leaders, the team consisted of diverse participants, from students and young professionals to parents, all united by a common goal – raising £1.50 per mile ridden to reach a collective target of £6000. Some team members had MS themselves or a direct connection to the disease, making the journey even more meaningful.

Throughout the 4-day ride, the team encountered challenges and triumphs. The route presented steep climbs in and around Eryi National Park (Snowdonia), but the splendid weather graced them with awe-inspiring views. The group navigated equally steep descents made challenging with rough roads in places. As they progressed through mid Wales and reached Brecon Beacons, the meandering country lanes offered tranquil surroundings and a taste of Wales’ natural beauty. The final day culminated with a breathtaking ride (both physically and metaphorically) from Talybont Reservoir to Pontsticill Reservoir, followed by a jubilant finish at Cardiff Bay, just outside the Wales Millennium Centre.

The Lôn Las Cymru Route

Length and Direction

Spanning 250 miles (400 km), the Lôn Las Cymru route runs between Holyhead and either Cardiff or Chepstow. For an optimal journey home with better train options, our preferred direction is from north to south, starting in Holyhead and finishing in Cardiff. This approach also places the challenging climbs early on, with the toughest ascent between Porthmadog and Llanidloes on Day 2. However, when finishing in Cardiff be prepared for slow-going bike paths on busy weekends for the final stretch along the River Taff.

Recommended Duration

While Lôn Las Cymru can be completed in a single day for those seeking an intense challenge, a 4 to 5-day adventure allows riders to savour the stunning surroundings and take on the climbs at a steady pace.

Accommodation and Food Options

Cyclists have various accommodation choices, including hotels, B&Bs, hostels, and campsites. Numerous towns along the route provide ample opportunities to replenish food and water supplies. While the route offers regular access to amenities, carrying plenty of snacks and planning for unexpected shop closures is important. Alternatively, van supported trips are a good option for a stress free ride.

We were fortunate to have some incredible generous hosts along the route including Canolfan Gymunedol Morlo (Gwelfor Community Centre), Porthmadog Football Club, Llanidloes Rugby Club and Kensington Baptist Church. Being hosted allows us to keep our costs to minimum and put more funds towards MS projects.
