Cow Ford 100 / 50 Miler

The event is an urban ultramarathon in Jacksonville, FL, with two distance options:

  • 100 miles
  • 50 miles

The course is organized as five sequential segments that pass through historic districts, riverfront neighborhoods, suburban corridors, and the downtown urban core. Segment distances are approximately 9.60 miles, 13.45 miles, 11.10 miles, 10.40 miles, and 6.65 miles. Terrain is primarily paved roads, shared-use paths, bridges, and greenways. Elevation is generally flat with several notable bridge climbs.

The 100 mile entrants complete the full course twice, running the return loop in reverse with a small adjustment. Course navigation files (GPX/KMZ) are provided and participants are responsible for downloading and following them. There are 8 to 9 aid stations with water and Skratch electrolytes; some stations offer hot food and there will be a mix of manned stations, unmanned coolers, and nearby commercial stops.

Safety measures reflect that the route has no street closures or police presence; participants must obey traffic laws, use legal crossings, and use lights and visibility gear during hours of darkness. Cutoffs are 36 hours for the 100 mile and 24 hours for the 50 mile. Crew and pacer policies include designated crew areas, one crew vehicle per participant, limited pacer access points, a required pacer waiver, and one pacer at a time.

Awards include custom buckles for 100 mile finishers, custom medals for both distances, top overall awards by gender, and other category recognitions depending on entrant numbers. Visit the organization's website for the most recent information.
