KEEN sea swimmers from all over the UK are signing up for a Pembrokeshire event that has established itself as an iconic feature on the open water calendar.

The Caldey Swim - covering around 2.5 miles between the island and Tenby - is set to take place on Sunday August 18.

Well over half the 100 places for the challenge have already been snapped up.

Swimming between Tenby and Caldey Island has been a long-established tradition for individuals and groups for many years, but 2013 was the first time the distance was covered under the umbrella of the Tenby Sea Swimming Association (TSSA), which has organised the town's legendary Boxing Day Swim for nearly 50 years.

The 2018 Caldey Swim had to be cancelled twice because of weather conditions, but fingers are crossed for fairer winds and calmer seas for this year's event.

Said TSSA chairman Chris Osborne: "After last year's disappointing double cancellation, we hope this challenging swim will be looked on kindly by whoever controls the sea and the weather."

The swim will be raising money for Tenby RNLI and Tenby Surflink, with both organisations helping to provide the all-important safety cover for the event.
