Shoreline Half Marathon & 5K

Saturday, July 10, 2021 • Hamlin, NY • Course Map

Note: A virtual option is available for this event, to be run anytime from July 10 to July 16. Registration details are included below.

Part of a two-day series of races that features a 13.1-mile half marathon, 5K and races for kids in addition to its triathlon, the Shoreline Multisport Festival celebrates its 39th running this summer, and its fifth annual with the half marathon race distance.

As its name suggests, the race will take runners along the shoreline of Lake Ontario here in the part of western New York State known as the Genessee region, just a short drive west from nearby Rochester.

The race unfolds largely within Hamlin Beach State Park, a popular park whose beaches attract thousands of visitors between Memorial Day and Labor Day every year, and which also features more than 10 miles of hiking and biking trails in addition to its one-mile nature trail near the beach.

For the half marathon, the running events take place on Saturday, while the triathlon takes place on Sunday. The race has a long history as one of the country’s oldest continuously running triathlon events, dating all the way back to its first running in 1980.

The course for the half marathon will unfold along the park’s hiking and biking trails as well as its paved park roads, and race organizers say the course is “relatively flat” though runners should expect to encounter uphills and downhills as well as rocks, twigs, tree limbs and perhaps even muddy terrain in spots, depending on the weather in the days leading up to the event.

The race organizers — the Rochester, N.Y.-based race event management company YellowJacket Racing — add that awards will be given out for the half marathon for the top overall male and female runners, as well as for the top 3 runners in each age group.
