RULES

Rules for the 2025 Season area available for download here, and will be included in the swim packet for each swim.

NOWSA recognizes the rules of the Marathon Swimmers Federation (MSF) as the standard for solo marathon swims. Except where clarifications or adaptations to local conditions are necessary, the NOWSA rules remain unmodified from those of MSF.

Changes to the swim rules, if any, by NOWSA shall take effect on 1 April of each year.

The original MSF Rules can be viewed in full at the MSF website.
