FYI — Due to new data on vaccine effectiveness with Delta and Omicron variants, for USATF sanctioned events that take place on or after January 7, 2022, being fully vaccinated no longer exempts select participants from the requirement to produce a negative COVID-19 test.

All athlete participants and medical providers must produce a negative COVID-19 nucleic acid amplification test (NAAT), performed within 3 calendar days of the first day of the event.
