Endorsed Modifications of MSF Rules


The MSF allows customizations of the Swim Rules section of the Rules of Marathon Swimming, via a Creative Commons Attribution 4.0 license. This policy is intended to give swimmers and organizers the flexibility to adapt specific swim rules to the local circumstances of a swim, while remaining within the general spirit of traditional marathon swimming.

While it is not required to obtain MSF's endorsement of a local rule customization, swimmers and organizers may choose to do so. We recognize the following local variants of MSF Swim Rules, and list them here as examples.
