Shoreline Half Marathon & 5K

Lace up for an unforgettable summer race experience at the Shoreline Half Marathon & 5K, set for Saturday, July 18, 2026, in scenic Hamlin, NY. This popular event, hosted within the beautiful Hamlin Beach State Park, offers both a challenging half marathon and a swift 5K, perfect for runners of all levels seeking a picturesque course along the shores of Lake Ontario. Typical race day conditions in mid-July feature highs around 84°F and lows around 63°F, with a modest 14% chance of precipitation, making for a classic summer running atmosphere.

Both the 13.1-mile Half Marathon and the 5K boast flat and fast courses, ideal for those chasing a personal best. The Half Marathon guides runners through the charming Hamlin countryside, beginning inside the park and culminating with a rewarding finish directly along the beach. While largely flat, the course utilizes paved park roads and some hiking/biking trails, with minor elevation changes that include gentle uphills and downhills, as well as potential natural terrain like rocks and twigs. The 5K, entirely contained within Hamlin Beach State Park, offers equally flat terrain with stunning views of Lake Ontario via the lakeside path. Aid stations are strategically placed on the half marathon course, providing water near miles 2, 5, 7, 9, and 12, with some past runners suggesting carrying additional hydration for warmer conditions.

As part of the historic Shoreline Multisport Festival, which traces its roots back to 1980, the Shoreline Half Marathon & 5K maintains a reputation for being a peaceful and well-organized event managed by YellowJacket Racing. The festive beachside finish is a highlight, where participants can celebrate their achievement with delicious breakfast burritos from Texas BBQ. With a cap of 830 participants across all races, this event offers a welcoming and less congested running environment, allowing you to truly immerse yourself in the natural beauty of one of New York's best State Parks.
