Celebrate a milestone with us! The October 2025 “Swimming Development” Issue of Outdoor Swimmer is our 100th edition, created by swimmers, for swimmers. This month we honour our roots—born in 2011 as H2Open—and showcase how outdoor swimming, and our community, have evolved.
Inside you’ll find training features and expert guidance on technique, safety, and performance to help you progress in open water. We also highlight inspiring stories of swimmers who cross oceans for causes, battle the elements, and champion people and nature alike.
Whether you’re squealing through your first cold-water dip or preparing for your next endurance challenge, this issue celebrates the creativity, camaraderie and determination of swimmers worldwide. Join us as we mark 100 issues of bringing you the very best in outdoor swimming—past, present and future.
