The popularity of open water swimming is booming, and why not? It can make pool swimming seem staid and predictable by comparison. But open water swimming has a rich history of people, places and events. A new website, Openwaterpedia, describes itself as “a unique, comprehensive, multi-lingual, authoritative online reference and research tool for any interested athlete, coach, administrator, official, media representative or fan of the endurance sports, triathlon and aquatic community.” It offers a large and growing collection of articles, videos, definitions and website links offered courtesy of another treasure trove of information, the Open Water Source.
