The Dee Mile swimming race, now in its 94th year, takes place on Saturday (July 30).
Race organisers are inviting members of the public to come down and watch the action.
Ciara Murphy, of Chester Triathlon Club, said: “It’s a fantastic sight, as 350 swimmers turn the water white as they head down river around the Crook of the Dee towards the finish at the suspension bridge.
"While some people prefer to spectacle from the river bank on the Meadows side, following the swimmers down, others take advantage of a superb viewpoint from the suspension bridge itself. The Groves also make a perfect grandstand."
The race is split into two, with the 1k swim starting on the Meadows and the 2k race starting from further upstream, both at 5.15pm.
In recent years, most people swim the event in wetsuits. But the race proudly retains its ancient 'Dee Mile Champion' title for the fastest swimmer without a wetsuit who must also live within five miles of The Cross in the centre of Chester.
