The Long Course Weekend June at Dinbych-y-Pysgod | Tenby

Pembrokeshire plays host annually to one of the most difficult but most rewarding events in Wales – the Long Course Weekend. This unique event lasts three epic days at the end of June.

The event caters for athletes of all abilities, from pro athletes to you everyday athletes who just wants to complete something incredible.

To kick-off the weekend on Friday evening, the Long Course athletes have The Wales Swim to complete – a 2.4 mile swim that takes place on Tenby’s North Beach.

On Saturday their attention turns to The Wales Sportive, and 112 miles of undulating Welsh countryside lined with enthusiastic crowds.

To finish the weekend, the athletes have the small task(!) of completing the 26.2 miles of The Wales Marathon, which is quickly establishing itself as a fantastic event in its own right.

More than 20,000 competitors have attempted the difficult terrain and challenging weather conditions on this punishing route since its first event in 2010. Of last year’s 1000 Long Course Weekend athletes, only around half could manage to cross the finish line and collect the final piece of the event’s unique medal design.
