Cow Ford 100 / 50 Miler
The Cow Ford event in Jacksonville, FL on March 20, 2027 features two distance options: 100 miles and 50 miles.
The course is an urban ultramarathon routed through five sequential segments that highlight historic neighborhoods, riverfront areas, suburban corridors, and the downtown core. The route is mostly on paved roads, shared-use paths, bridges, and greenways, generally flat with notable bridge climbs. The 100 mile distance consists of two laps of the full course, with a slight adjustment on the return loop.
Navigation relies on provided GPX/KMZ files and occasional course markings; participants are responsible for following any minor course updates. Safety rules require obeying traffic laws, using legal crossings, and wearing a headlamp and visible lights or vest during night hours. The course is about 98% accessible via roadway, bike path, or sidewalk, with one roughly 1 mile section in Ortega lacking a dedicated shoulder or sidewalk.
Cutoffs are 36 hours for the 100 mile course and 24 hours for the 50 mile course. Aid support includes eight to nine aid stations with water, Skratch electrolytes, some hot food at select stations, and a mix of manned stations, unmanned coolers, and nearby commercial stops. Crews may meet runners only in designated areas and are limited to one vehicle per participant. Pacers must sign a waiver, one pacer at a time, and must follow the same participant rules; earlier pacer access is allowed for runners aged 60 and over. Awards include custom buckles for all 100 mile finishers, medals for both distances, top overall placements, and special recognition awards.
