The Next Loop Endurance Series offers a unique trail event format where participants can decide loop by loop how far they want to go. Held on a scenic 3.1-mile (5K) trail loop, runners start a new lap every hour, complete as many as they can, and each loop counts toward their total distance.

Course Overview

• Scenic 5K loop: A clearly marked 3.1-mile trail through natural terrain.
• Loop-based structure: Runners begin each loop on the hour.
• Flexible distances: 1 loop = 5K, 2 loops = 10K, 4 loops = Half Marathon, 9 loops = Marathon, 10 loops = 50K.
• Strategy-friendly: Every completed loop counts toward your official result, with loop time recorded.

Scoring & Format

• Hourly starts: Each loop begins at the top of the hour.
• Total result: Ranked by the number of loops completed and combined total time.
