A charity sea swim in Cornwall in June has attracted more than 200 people.
The one-mile (1.6km) "Castle to Castle" swim, to raise money for the RNLI, has become an annual event.
The charity said 240 people had already signed up to swim across the Fal from Pendennis Point to St Mawes in Falmouth on 3 June.
Last year's swim, which included EastEnders actor Steve McFadden, raised more than £50,000 for the charity's services in Devon and Cornwall.
The actor, who plays Phil Mitchell, has a home in Cornwall and has taken part in two previous swims.
"I'm gutted to miss the RNLI Castle To Castle swim this year - it's always a fantastic challenge for a brilliant charity," he said.
McFadden is involved in the Queen's Diamond Jubilee Pageant, but said he would be sending his best wishes to the swimmers who were "flying the flag in Falmouth".
An optional six-mile (10km) cross-country run has been included in the 2012 event.
The route will start at St Mawes Castle and continue along the coastal footpath to St Just, over the Roseland peninsula and back down the Percuil River to St Mawes harbour.
The RNLI said the swim, which began as a small fundraiser in 2009, had turned into a very popular event.
"To have this number of entries at this stage is really good... and hopefully means we'll end up with more than the 400 or so who took part last year," spokeswoman Tamsin Thomas said.
People can register for the charity swim on the RNLI website and the closing date for entries is 27 May.
