Online Entry Now Open

The River Adur 5km Swim is now in its 5th year and with the tide with you all the way it’ll definitely be the quickest 5km you’ll ever swim.  Having doubled numbers from our inaugural swim and we’re now looking to have a maximum entry of 350 for this event. There are two categories: Fin Swim & Just Swim. Just Swim is for swimmers looking for another challenging swim unaided and Fin Swim is just that, you can wear a pair of fins of your choice to speed your way to finish. Wetsuits are compulsory

We’ll take you by vintage coach to the start, drop you off at high tide and you make your way back to Shoreham-by-Sea on the tide.  You’ll have to negotiate the sandbanks & bridges for the quickest route, we guarantee some of you will run aground! The closer you get to Shoreham the tide will pick through the sandbanks and mussel beds to push you all the way to the finish line. The start time will be announced once the date has been confirmed to give you the best chance of securing a personal best and enjoyable swim.

Competitors will receive a memento, hot & cold drinks, flapjack, silicone swim cap and Protein Balls. Shoreham town centre is conveniently located across the bridge with plenty of bars and restaurants along the river for that perfect post race drink or meal; we might event join you!

Please not this is a morning start for 2020 – 3:30pm.
