From Endurance Grid
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
Swimming events drop you into something that demands navigation, feel, and focus all at once. It's a sport that rewards the quietly competitive — the ones who do the work in the water before anyone's watching.
Open water races from 1 mile to marathon distance. Just you, the water, and whatever you've got left.
