Conquering Windermere: Luke’s 17K Open Water Swimming Challenge

swimming medal

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!
