From the organizer

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.

Course Safety This event takes place on open roads with no street closures and no police presence. Runner safety is the top priority, and all participants must strictly follow these rules:

• Obey all traffic laws at all times • Only cross streets at legal crosswalks and traffic signals • No jaywalking • Never attempt to cross multi-lane roads outside of designated crossings • You are not faster than a vehicle — use patience and good judgment

Participants should stay aware of their surroundings at all times, yield to vehicles and pedestrians, and remain on sidewalks or paths where available. Running on the shoulder or grass may be necessary in limited areas and should only be done when safe.

Visibility & Gear Reflective clothing, vests, and/or lights are strongly encouraged. Early morning visibility matters — make yourself easy to see. Running with a buddy or small group is strongly recommended. Carrying a phone and some form of payment (cash or card) is encouraged in case supplies or assistance are needed.

Support & Aid This is a low-key, no-frills event. There will be no official aid stations. A small water table will be available near the start/finish. Participants should carry their own hydration and nutrition.

Entry Fee / Donations A donation to First Coast Women’s Services is highly encouraged and greatly appreciated. Donations of $25 or more receive free swag!
