Cow Ford 100 / 50 Miler : Jacksonville, FL

The Cow Ford event in Jacksonville, Florida, is presented as an urban ultramarathon offering both 100 Miler and 50 Miler options. The course is described as five sequential segments that together form a continuous route through historic neighborhoods, riverfront areas, suburban corridors, and downtown streets.

  • 100 Miler
  • 50 Miler

The route uses paved roads, shared-use paths, bridges, and greenways and is generally flat with notable bridge climbs. Segment mileages are given approximately: Springfield Loop (~9.6 miles), Ortega Loop (~13.45 miles), SUP to Baymeadows (~11.10 miles), Old Kings Road to Acosta Bridge (~10.40 miles), and Urban Core Finish (~6.65 miles). There is about a one-mile section in Ortega (around miles 12–13) with no sidewalk or shoulder; runners are expected to use the road edge or grassy verge there. The course is described as roughly 98% accessible via roadway, bike path, or sidewalk.

Safety and navigation measures are emphasized: runners must obey traffic laws and use legal crossings, use visible lighting in low light, and download provided GPX/KMZ route files and any updates; participants are responsible for navigating the course. There is a 16 hour overall cutoff (approximately a 19 minute per mile pace). Aid is provided at 8–9 stations with water, Skratch electrolytes, standard aid station fare, and hot food at two locations. Crews are allowed only in designated areas with one crew vehicle per participant. Pacers are permitted after the halfway SUP point, with special allowance for runners 60 and over to add pacers earlier; all pacers must sign a waiver and only one pacer may accompany a runner at a time. Awards include top overall and age-group recognitions, with additional honorary and random awards. Visit the organization's website for the most recent information.
