Cotter Bridge Ultra

Event Overview

The Cotter Bridge Ultra is a timed event held at Big Springs Park in Cotter, Arkansas. Participants navigate an out-and-back course on a multi-use trail alongside the White River. The route is primarily flat, consisting of fine crushed gravel with approximately 15 feet of elevation gain per mile. The path is wide, offers shade, and is designed to remain manageable during rain.

Race Format and Distances

The competition follows a specific format where runners must complete a 4.1667-mile loop every hour. A new lap begins at the top of each hour, and participants must finish the loop in under 60 minutes to remain in the event. Failure to complete a lap within the time limit or failing to start a lap on the whistle results in a disqualification. The final lap for each distance serves as a "hot lap" where speed determines the final placement.

The available distances include:

• 1 Hour: 4.1667 miles
• 3 Hours: 12.50 miles
• 6 Hours: 25 miles
• 12 Hours: 50 miles

Logistics and Regulations

Runners are permitted to set up a personal aid or crew tent near the start line on a first-come, first-served basis. While the event provides basic nutrition, water, and electrolyte drinks at a central pavilion, participants are expected to be largely self-sufficient. This is a cup-less and low-waste event; runners must provide their own bottles and eating utensils. The course is open to the public and pacing is not permitted. For the longer distances, on-site meals are provided at the six-hour and twelve-hour marks. Visit the organization's website for the most recent information.
