The Tenby Long Course Weekend began in style this evening (Friday) as hundreds upon hundreds of athletes tackled the opening leg of what has become a world class sporting event.

Big crowds gathered in humid conditions to see athletes take on the swim around the North Beach.

Each lap around of the swim is 1.2miles long with athletes choosing the length of their individual challenege.

Up next is the cycle ride on Saturday followed by the running events on Sunday.

Check back throughout the weekend for more information and pictures.
