Documented Swims

MSF Documented Swims logo

MSF Documented Swims is a platform to document and ratify independent* open-water marathon swims. It is a widely recognized gold standard, ratifying over 130 marathon swims since 2013, including dozens of “firsts” and the world records for Longest Overall Open Water Swim (Sarah Thomas) and Longest Ocean Swim (Chloe McCardel). Each Documented Swim undergoes rigorous review to ensure the highest standards of integrity, thoroughness, and adherence to standard marathon swimming rules and conduct.

To submit a Documented Swim:

* An “independent” marathon swim is a swim in a body of water not governed by a recognized local sanctioning organization (e.g., the CSA or CS&PF for English Channel swims).
