A local radio presenter is to walk along the Essex coastline to raise awareness of the RNLI.
BBC Essex host Ray Clark will visit the county's six lifeboat stations between Tuesday 26 and Thursday 28 April.
The route of about 50-miles (80km) is in aid of the Burnham Floating Lifeboat House appeal, of which he is a patron, that is hoping to raise £150,000.
He will broadcast his show live from three locations along the walk between 0600 BST to 0900 BST.
The show will come live from Harwich on Tuesday, Walton-on-the-Naze on Wednesday and West Mersea on Thursday.
Burnham-on-Crouch resident Mr Clark, 56, explained his motivation for the walk.
"Every year the RNLI rescue hundreds of people along the Essex coast," he said.
"This is my chance to raise the charity's profile as well as the other emergency services that help to save so many lives.
"I can't wait to get my walking boots on, but it will be a challenge."
The Burnham RNLI station is in need of a larger boathouse after a new lifeboat was donated to it.
In 2010 its crew well called out to around 40 incidents.
