NEW LANE NOW OPEN! We’ve added an extra lane to welcome more swimmers, with different pace options available to help you find your fit.
💙 Even better, this year we’re swimming in support of The Parenting Network Portsmouth, helping raise awareness and support for a fantastic local cause.
📅 Sunday 25th October
