From its inception, the Marathon Swimmers Federation and Forum and have been intended as a free resource to the global community of current, former, and aspiring open-water marathon swimmers.

The direct financial costs of making this resource available on the internet have been supported by occasional swag and calendar sales. In the interest of user experience, we do not do third-party commercial advertising.

Some of our members have expressed interest in making more direct financial contributions to MSF, to further incentivize its development. While it is certainly not expected, the extra support does make a difference, and is very much appreciated.
