Event Details
The St. Marks Duathlon takes place on March 15, 2026. It features three events: a standard individual duathlon, a relay duathlon, and a "Fat Tire" duathlon.
Course
The multisport event consists of a 5 km run, followed by a 20 km bike ride, and finishes with a 2.5 km run. It is a USA Triathlon sanctioned race, requiring all participants to have a valid USAT membership or purchase a one-day license.
The course is marked with colored spray chalk arrows (red for the first run, yellow for the bike, and white for the final run). The course is open to traffic. Law enforcement and volunteers will be at major intersections, and athletes must follow all traffic laws.
Facilities & Rules
One aid station with water is located on the run course. There are no aid stations on the bike course; athletes must carry their own fluids. Post-race food and beverages are provided. Four portable restrooms are located near the transition area. Transition racking is first-come, first-served.
Special Divisions
- Relay Division: Teams of 2 or 3 athletes can compete. Awards are given for top male-only, female-only, and mixed teams.
- Fat Tire Division: This separate category allows bikes with knobby or heavily grooved tires of 1.5 inches or greater width. Gravel bikes with such tires are eligible. Standard USAT rules apply.
