Supertri New Jersey

Supertri New Jersey, formerly known as the Challenge New Jersey State Triathlon, arrives at Mercer County Park on Sunday, July 19, marking the first year the iconic New Jersey Triathlon will be owned and operated under Supertri, the global leader in short course triathlon. Long regarded as one of the top triathlons in the United States, the race is celebrated for its lightning-fast, flat course and its ability to welcome athletes of every experience level, from first-timers to seasoned competitors.

Held in the heart of Mercer County Park, Supertri New Jersey delivers a fast, championship‑level race experience highlighted by a sheltered swim in Mercer Lake, a closed‑road bike course widely regarded as one of the fastest on the East Coast, and a flat, spectator‑friendly run through the park. Athletes can choose between Sprint and Olympic distance options for individual or relay competition, each designed to showcase speed and performance. Both courses are known for their flat terrain, calm swim conditions, and fully closed roads, allowing athletes to race confidently at full speed.
