Tri-Base Triple Nickel Triathlon

The Tri-Base Triple Nickel Triathlon offers a unique challenge for authorized military personnel on November 8, 2026, at Naval Air Station Jacksonville. This exclusive event features a compact yet intense triathlon format with a 500-meter swim in the St. Johns River, followed by a 5-mile bike ride through Antenna Farm and Perimeter Road, and concluding with a 3.1-mile run along the east side of NAS Jacksonville.

Athletes can expect a well-organized event schedule featuring separate waves based on gender and team categories.
The swim in the St. Johns River provides a refreshing start, while the bike course takes competitors through scenic areas with varied terrain that test endurance and skill. The running portion offers a flat yet fast route along the base perimeter, providing participants with an opportunity to showcase their speed as they race towards the finish line.

Race awards are presented to first-, second-, and third-place overall male and female competitors as well as active-duty military males and females in individual categories. Team awards will also be given out for top-performing teams. The pre-race meeting is mandatory at the swim start area at 7:45 AM, ensuring all athletes understand race rules and procedures.
Transition management includes a designated transition zone with ample bike racks and separate slots for each participant.
