The NJ Endurance Classic Half Marathon, 10k, 5k

Get ready to kick off your summer running season at The NJ Endurance Classic Half Marathon, 10k, and 5k on Sunday, June 21, 2026, in scenic Bridgewater, NJ. Set within the beautiful 343-acre Duke Island Park, this event offers a fast and flat course along the picturesque Raritan River Greenway, making it an ideal race for chasing personal bests or enjoying a scenic run. The tree-lined and shaded paths provide a refreshing environment, perfect for racing on a typical June day, where conditions usually see highs around 84°F and lows around 62°F with an 18% chance of precipitation.

Runners in all three distances – the Half Marathon, 10K, and 5K – will enjoy a spectator-friendly looped course, primarily paved, which winds through the natural beauty of the park. The 3.35-mile (or slightly varying for Half Marathon) loop design means continuous support from aid stations, offering water, Gatorade, and power gels at three points per loop to keep you energized. With live chip timing providing splits for every loop and real-time tracking available, friends and family can follow your progress every step of the way, cheering you on as you pass the start/finish area.

Beyond the course, The NJ Endurance Classic is renowned for its exceptional runner experience. Participants will receive a high-quality technical t-shirt, a commemorative die-cast finisher medal, and access to free race photos and personalized finisher videos. The post-race celebration features delicious fresh Brooklyn bagels with a variety of spreads, adding a unique local touch to your achievement. With generous awards for the top three overall finishers and age group winners, this well-organized event by CityTri promises an unforgettable race day experience for both seasoned athletes and newcomers.
