The Dart 10k – Open Water Distance Swim

The Dart 10K is a river swim that starts with a boat trip from Dartmouth up the course before mooring and letting the swimmers go. In fact there are three boats, each with about 150 swimmers on board, and a buzz and anticipation that open water swimming often brings.

The course starts in a meandering, high-sided landscape before opening up into a wide, flat valley where the first feed station awaits. Some jelly beans and water before you head into a long bend round to Dittisham, then through a narrower section with lots of boats. At this point you realise the tide is quite strong as you fly past the boats, and only narrowly miss a few!

The final long straight into Dartmouth comes faster than expected, and you cross the line to receive a branded mug of hot chocolate as a reward. It’s a quick and exhilarating race, a little over 2 hours (comparable to the 3 hours it would take in a lake).

The Hurly Burly – Open Water Distance Swim

The Hurly Burly is another level, and its name is definitely appropriate. It’s wild, fast, and leaves you breathless and grinning from ear to ear.

You set off at 7:30 in the morning as the tide turns in and swim into the estuary. You swim straight off the beach along the sea wall before being taken by the current, heading straight for a bridge at pace. Keep your head up and sighting as it passes by in seconds, and you sigh in relief you didn’t hit it! They guide you sideways even though it looks clear straight on, and once you’ve hit a sandbank inches below you realise that following them is the only way forward. The water is choppy, the sky blowing past and the Welsh valley serenely beautiful.

At the finish, you have to sprint from left to right without passing it by, then onto land, where a band of drummers greets you. Less than 1.5 hours, wide-eyed and bashed, a wonderful swim. There are 600 swimmers, and pretty much all of them end up in the pub for a bacon sarnie and a slowing of the pulse.

Swims like these underscore the pleasure of swimming in open water and swimming distances you rarely attempt in the pool.

Windermere is England’s longest lake and for open water swimmers it’s something of a rite of passage. For our member Luke, it was a challenge that had to be taken on, so 2025 became the year to do it.

The swim was organised by Chillswim, who run several Lake District events including the iconic Windermere crossing. September 6th was the date, with around 300 swimmers signed up. Entries require you to declare your intended pace, as swimmers are set off in waves. For the first hour you must stay with your wave, so pacing matters – too slow and you’ll spend the swim frustrated, too fast and you risk blowing up early.

Training started in the pool through the winter before moving into open water in early May. Luke kicked things off with a 5km lake swim, where he was beaten by his 15-year-old son, a reminder he is not as young as he once was! However rather than denting morale, it sharpened Luke’s focus.

Next up was a 9km swim at Lake Bala. True to form, the Welsh weather delivered rain, wind and chop. It was a tough and slightly unnerving experience, especially knowing it was only half the distance of Windermere. Confidence returned later in the summer during a 4.5 hour training swim in a large, flat-calm lake in France. Luke swam the entire session alone (phone safely in his tow float and always close to shore). After that, he was ready!

Event day begins with registration in a field at the north end of the lake, followed by a minibus ride to the southern start, an uncomfortably long journey when you know you’ll soon be swimming the whole way back.

The route is 17km (11 miles in the event’s preferred metric). Feed stops appear every mile, with small boats offering isotonic drinks and jelly babies, yum! Luke also carried carbohydrate pouches in his tow float and aimed to refuel roughly every two miles, about once an hour.

The opening miles were perfect. Flat calm water, a group of around 40 swimmers, and a pace that felt just right. The first feed stop broke the pack apart and from there it became a steady process of overtaking swimmers from earlier waves.

Just before halfway, the course cuts across the lake from east to west to keep swimmers clear of other lake traffic. It’s a welcome change of direction before the halfway point and the scenic stretch past the islands, where the waves begin to merge and the water fills with swimmers.

Beyond the islands the lake opens into its wider northern section. More boats, more waves and by now the weather had picked up slightly. Fatigue started to creep in, and thoughts turned increasingly to the large yellow rubber duck marking the finish line. At one point Luke spent nearly a mile chasing a swimmer with a small yellow duck tow float before realising it wasn’t the finish..!

The final mile crosses toward Ambleside, the real duck finally in sight. Tired arms are replaced by determination as the shoreline gets closer. At the finish, the enclosure is full of tired but happy swimmers, supporters and volunteers and the unmistakable camaraderie that seems to define open water swimming.

Huge well done to you Luke — you’ve shown the way and inspired a few of us to give it a go! An iconic swim, and a brilliant one to tick off the list!
