Alex Manfull Fund 5K Arlington, VA   Jun 13, 2026

Join Jadin O’Brien, Olympic athlete, 3x NCAA pentathlon champion and 10x All-American (heptathlon) winner, for this in-person and virtual 5K sponsored by The Alex Manfull Fund. The 5K aims to raise awareness and advance research on debilitating infection-associated neuroimmune disorders (including PANS and PANDAS) that affect young people. The 5K is part of the organization’s 36 Hours for PANS and PANDAS Advocacy in Motion event. Funds raised will support cutting-edge research at top-tier institutions across the country.

The event commemorates the life of Alex Manfull, who died at age 26 due to PANDAS. Susan and William Manfull established the Fund in their daughter’s name with the vision that no life ever again be cut short-or interrupted-by these illnesses.
