SAFETY

A Shared Responsibility:- No matter what inspired you to become an athlete, you’re responsible for showing up at the starting line fully prepared for the challenge ahead of you. Safety in the sport is not just the responsibility of the National Governing Body, sanctioned events and race directors, who are subject to the scrutiny of USATF sanctioning process and expected to uphold the best safety protocols. It's also the responsibility of the athlete.
