OSS swims aren't quite like other swims; we're all about the people, and the journey

Jess Rose

Start the season in July with a weekend at the beach and a sandy bottomed swim with a Swoosh to finish, build up over summer for a Dart 10k marathon through the green hills of Devon, and then welcome in autumn with the Hurly Burly, possibly the world’s fastest 10k, with winds, weather and fire pits in North Wales.


We are hoping the OSS events will run again in 2022 and that ticket sales will happen in Spring, but we lost the old event team during Covid. Please pencil in the dates for now, and we will email all subscribers to elsewhere as soon as we have news (you can also keep an eye on the event webpages and OSS social media channels). Here is a link to sign up for elsewhere, the monthly online journal from The Outdoor Swimming Society. An update will be shared through all these channels as soon as we have it, so please avoid contacting the team about one before that.

Bantham, Devon

How far can you swim before the tide turns? The Bantham Boomerang swim is a new swim for 2022: a 7-10km swim on the Avon Estuary in Devon, taking place on a Friday afternoon with a BBQ afterwards. The distance swum will depend on how fast you swim, but all swim speeds are welcome. Swimmers will be set off according to their speed, which you are asked to know by the day. Some swimmers will make it all the way to the turnaround pontoon around 5km upstream before the tide turns, others will have a shorter journey. Our fantastic safety team will be there to support you every step of the way.

Bantham, Devon

The Swoosh is a gentle 6km swim down the Avon Estuary, with a “swoosh” at the end. Once again, we will have the perfect beach location for a weekend with friends or family, with a MiniSwoosh for children. A great swim to start the season: water is typically 14-17°C, and swimmers usually take between 90 minutes and 2 hours to complete the swim.



3rd – 4th September 2022

Totnes and Dittisham, Devon

A spectacular swim starting in Totnes in Devon and winding its way around the Sharpham Bends to the sailing village of Dittisham (dit-sum to locals). It has it all: adventure, joy, challenge and a contentment of swimmers (the communities chosen collective noun). At the end there’s a festival field with hot tubs, wood fired pizza, deck chairs, local beers, a playground, and lots of other lovely treats to celebrate our biggest event. Wherever you are on the swim spectrum right now, put enough determination, lessons and training into picking up strength, style and stamina, and you can probably do it.

Barmouth/Abermaw, North Wales

Tidal assistance at its finest (fast enough it’s almost into the bore category). Hot chocolate, wood fired hot tubs and fire pits greet all swimmers, runners and run-swimmers as they coalesce at the finish to celebrate a morning of exploring the Mawddach Estuary.

The swim and run routes weave between mountains, not hills. Waves, geese, camaraderie and our superb safety crew line the swim route, whilst runners will explore the breath taking Mawddach Trail, crossing the iconic Barmouth Bridge and watching the tide come in along the estuary as you make progress towards the historic Penmaenpool Toll Bridge. One of the The Outdoor Swimming Society team’s favourite swims, you’re in for a treat if you join us.

We ask that swimmers are able to swim 1 mile in 35 minutes or under to guarantee reaching the finish with tidal assistance and swimming, rather than safety crew leapfrogging.

The 2022 date is a moveable feast because of scheduled bridge works, but we’re working on finding something that works.

The OSS team of volunteers are the lifeblood of events. Marshalling the events and caring for the swimmers are great ways to support the OSS, and there are plenty of perks too, including free meals, merchandise, and VIP status with early bird access to next year’s events. If you or your supporters would like to be involved in the 2022 events please sign up for elsewhere, the monthly online journal from The Outdoor Swimming Society, to get updates on volunteering.

A message from Event Director, Kate Rew

How we (that’s me and maybe you, the swimmers) have missed these events! With fingers crossed for 2022, here are some of my favourite memories:
