Documented Swims
MSF Documented Swims is a platform to document and ratify independent* open-water marathon swims. It is a widely recognized gold standard, ratifying over 300 swims since 2013, including dozens of “firsts” and the world distance records for Longest Open Water Swim and Longest Ocean Swim. 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).
