The Frosty Aquathlon is a well-established, open to all and is a highly popular swim/run race.
2025 will be the 29th anniversary of the event which is held in the Littlehampton Wave. (postcode BN16 2NA) on the West Sussex south coast. The swim is in an 8 lane 25 metre pool – the run course is a loop around Mewsbrook Park before heading out onto the seafront promenade. The Frosty is traditionally held on the first Sunday in March and many competitors view it as an annual curtain raiser to their new season and to find out how successful their winter training has been. As the name suggests, it can be cold and we have even seen snow. But don’t worry, the swim is indoors and the transition at pool side, which means that you can pull on your trainers and get ready for the run in the warm.
