Every member of the Epic Lifeguard Team has American Red Cross Waterfront Lifeguarding Certification in addition to basic American Red Cross Lifeguarding Certification. This means that our guards have all taken and passed an additional course in which they received training in the knowledge and skills needed to prevent and respond to emergencies in non-surf, open-water areas. Our superbly trained lifeguards are yet another reason our races are so Epic! Our lifeguards are also able to keep our swimmers safe thanks to our official SUP company, Red Star Board Company. We’re very grateful to have Red Star as part of Epic team.
