Standing With Her
Join us for the Heisenberg Half Marathon, a charity run honoring our beloved F3 brother Jeff McCrea (“Heisenberg”) while supporting First Coast Women’s Services.
This event proudly benefits First Coast Women’s Services, an organization dedicated to walking alongside women and families during some of life’s most challenging moments. Our motto, “Standing With Her,” reflects both their mission and the way Jeff lived—showing up with compassion and standing with others when it mattered most.
What began as a personal training run has grown into a community event welcoming runners and walkers of all abilities.

• Obey all traffic laws at all times

• Never attempt to cross multi-lane roads outside of designated crossings
