TESTIMONIALS

Just the most beautiful swim, through a constantly changing panorama of the loveliest countryside with a privileged view of fabulous private houses and gardens, glittering sunshine, water, woods, boats, birds and shoreside ramblers. What a convivial crowd of swimmers united in their enjoyment of a great day out on a great waterway, all superbly organised by a host of cheerful volunteers. Not to be missed by anyone who loves the pleasures of open water swimming in all its fulfilling splendour!

James N, Thames Marathon 2024

Another fantastic Henley Classic and as always the care the team take for the swimmers is excellent – making sure we’re safe and have a great time. There’s something very special about swimming up the Henley Royal Regatta course as the sun rises and it’s a great event for both newer open water swimmers and those who are more experienced. A highlight on the swimming calendar and I’ll be back again next year!

Steve H, Selkie Henley Classic 2024

First event in UK for me as a Dutchy, but what a well organised swim. Vibe was great, finish location brilliant…. Planning to do one swim abroad per year, so maybe another Henley Swim event!

Henriette S, Club to Pub 2024

This was my first Henley Swim and my first long river swim. I loved it, it was an amazing experience and I want to do it again! The pre-event communication was detailed and helpful, and on the day the crew were professional and friendly. I felt reassured by the number of people on the water guiding us and keeping us safe. The feeding stations were lovely – such a nice atmosphere. It’s amazing how far one can go when powered by Haribo sweets! It was the nicest open water swim I have ever done!

Cecilia B, Thames Half Marathon 2024

Another great Henley Swim Festival. The extra night camping and activities on Saturday before swimming on Sunday really added to the event. A great well organised event and just a fantastic chilled out weekend with fellow swimmers in a beautiful location.

ABOUT US

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.
