The Long Course Weekend returns to Pembrokeshire with over 11,000 athletes, 35,000 supporters from 56 nations, ready to compete over three days.

Each summer, Pembrokeshire plays host to one of Wales’ most iconic endurance events. Athletes from around the world descend on Tenby for three unforgettable days of sport, spirit, and scenery.

Athletes compete across three disciplines over the course of a weekend, picking the distances that suit them best.

Temporary road closures and restrictions to facilitate the annual Long Course Weekend in Tenby and its surrounding areas will be in place for the marathon on Sunday - although a redesigned course has been introduced for the cycling event taking place on the Saturday, Pembrokeshire County Council has stated.

A changed route this year sees the cycling event miss out Saundersfoot, and its famous ‘Heartbreak Hill’

The organisation ‘Love Saundersfoot’ shared: “This year’s The Long Course Weekend taking place this weekend will no longer be routed through Saundersfoot during bike day.

“All visitors to the area are very much welcome to the village where roads and parking will open.

“We wish Long Course Weekend and all competitors all the very best on the new bike course and hope everyone enjoys this fantastic event.”

In fact, there will no road closures at all for Saturday’s cycling event for 2026, with the challenge taking place on open roads.

Activity Wales Events, the organisers of LCW shared: “The year, all LCW Wales bike routes will take place on open public roads. There will be no road closures for the bike section.

“Whilst the roads are open, please avoid them if possible, as certain times they can be very congested.

“We kindly ask all drivers to allow extra time for journeys to be patient when travelling behind cyclists.”

Long Course Weekend will kick off from Friday, June 26, starting with the Wales swim on Tenby’s North Beach from 5pm.

Saturday, June 27 will see the Cycle Sportive take place; followed by the marathon event on Sunday, June 28.

A spokesperson for Pembrokeshire Council shared: “As in previous years it will be necessary to introduce a number of traffic restrictions on the Sunday to enable the marathon to take place in a safe environment.

“The Croft and a section of the Norton (White Lion Street to The Croft) will be temporarily closed on the Friday evening between 4.30 and 6.30pm, in the interest of public safety due to possible thronging of spectators watching the swim event. Access to properties on The Croft will be managed.

“The start and finish on both Saturday and Sunday is from the Salterns car park [in Tenby], with full road closures implemented on a rolling basis for the Marathon on the Sunday.”

Road closures will be carried out on a rolling programme, with the roads re-opening following the last athlete and when it is safe to do so.
