Race Director’s Guide
This manual serves to define the requirements and expectations for being part of the 2023 UltraMarathon Swim Series.Each race on the Series will have a responsibility to adhere to these requirements and expectations – and will also have a key voice to help the Series grow and prosper. Together as a global community, we wish to establish a uniform format for the benefit of each event and each swimmer.
Monthly meetings via Zoom and post-race meetings will be held so everyone’s opinions, observations, and recommendations can be heard and considered regarding (1) officiating, (2) rule interpretations, (3) pre-race registration, (4) organizational procedures, (5) in-race and post-race reporting, (6) media relations, (7) venue signage, (8) escort boats, (9) technical support from timing to buoy placement, and (10) disciplinary actions.
