Cow Ford 100 / 50 Miler - Jacksonville, FL

The event on March 20, 2027 is an urban ultramarathon in Jacksonville, Florida that follows city streets, riverfront paths, bridges, and greenways. Two distances are offered:

  • 100 miles
  • 50 miles

The course is organized as five sequential segments with distinct character and scenery. Segments and approximate lengths are: Springfield Loop (~9.60 miles), Ortega Loop (~13.45 miles), SUP to Baymeadows (~11.10 miles), Old Kings Road to Acosta Bridge (~10.40 miles), and an Urban Core Finish (~6.65 miles). Terrain is mostly paved roads, shared-use paths, bridges, and greenways. The route is generally flat with notable bridge climbs. 100 mile entrants run the full course twice, completing a reverse loop on the return with a slight adjustment.

Safety and logistics note that there are no street closures or police presence along the route, so participants must follow all traffic laws and use crosswalks. After dusk runners must use headlamps and visible safety lights or vests until the morning hours. One roughly one mile section in Ortega has no sidewalk, requiring runners to use the road edge or adjacent grass. The course is about 98 percent accessible by roadway, bike path, or sidewalk.

There are 8 to 9 aid stations, two station locations at private residences, unmanned coolers, water and Skratch electrolytes at manned stations, and hot food at least at two aid stations. Time cutoffs are 36 hours for the 100 mile distance and 24 hours for the 50 mile distance. Crews are restricted to designated areas with one crew vehicle per participant. Pacers are allowed under specified rules including a signed waiver and one pacer at a time. Custom buckles are provided for all 100 mile finishers and medals for both distances.
