Documentation Requirements

MSF Documented Swim submissions should include a diverse portfolio of data and documentation, which provides a complete story and compelling evidence for the swim. See marathonswimmers.org/swims for numerous examples of well-documented swims.

Feel free to ask questions about route definition, rules, observers, GPS tracking, and other issues before the swim. It is OK to wait to submit the ratification request after the swim is complete.

Submit a Ratification Request

Significant time and effort goes into collecting, formatting, reviewing, and publishing world-class Documented Swim reports. For MSF Documented Swims to be a sustainable project, we charge a swim ratification fee. This fee includes a commemorative printed GPS track map, and is refundable if the swim is not successful or not ratified.

A current MSF membership is required to submit a Documented Swim. If you are not currently a MSF member, please purchase a membership before filling out the form below.
