WE'D LIKE TO SAY a huge thank you to everyone who came down to The Telegraph Outdoor Show at the Excel Centre in London to listen to Calum and I share our swimming stories and the inspiration behind diving into maelstroms in the Arctic Circle. It was great to chat to you all afterwards and hear about your own swimming stories and plans for the watery future. It’s always very humbling to meet so many people who are so passionate about outdoor swimming, for those of you who couldn't make it down hopefully we'll meet you at a talk or in the water soon...
If you missed out and you're looking to catch the next Telegraph Travel Show here's Ten Reasons to get in early and pick up a ticket.
