This was my first time at the Club to Pub event. It was well planned organised and I loved it! It is an iconic swim and a fun swim to do. Absolutely love the beer and a medal as a bottle opener at the end! My partner could watch the whole swim and enjoyed the atmosphere too. Recommend 100% will be back next year!
Club to Pub 2026
Had a brilliant time at Club to Pub! The event was really well organised from start to finish, with a fantastic atmosphere and friendly volunteers. The swim itself was great, and there’s something special about finishing by climbing out and heading straight to the pub. Such a unique event that’s enjoyable, relaxed and well worth doing. I’d definitely recommend it and will be back.
Club to Pub 2026
A brilliant swim with the sun on my back and The Thames clear and calm. Great support crew, beautiful scenery and and my 10th (I think!) Thames Marathon completed. Just gets better every year. Thank you for taking over the organisation of a brilliant event after last years’ disappointment
Thames Marathon 2026
My first Marathon Swim and what a great one to start with. I felt safe, supported and welcome. All the volunteers and organisers were fantastic offering up Vaseline for my neck, supplying the perfect refreshments each leg and on the water the canoeist were just as good. In the perfect place for spotting and encouraging us all along the way. Can’t wait to have another go next year.
Thames Marathon 2026
Open water swimming events have been held on the Thames since the 1890s, but this more recent reincarnation began in 2004 when two ex-rowers decided it would be fun, and a little bit naughty, to swim the regatta course at first light.
As open water swimming has grown in popularity, so has the interest in swimming in Henley. While the Henley Classic has maintained its early morning charm and excitement, Henley Swim now organise other open water swimming events in the summer months, including a long-distance endurance swim from Henley to Marlow, and an evening swim that ends at the pub.
Every year the events attract both new swimmers and people returning again and again, from all over the world. We welcome you all and thank you for playing your part in building the strong and supportive Henley Swim community that exists today.
