Grand Island Half Marathon & 10K

Saturday, May 4, 2024 • Grand Island, NY • Course Map

Featuring a scenic out-and-back course along the West River Parkway in New York’s Beaver Island State Park along the U.S.-Canadian border, the Grand Island Half Marathon & 10K is among the state’s smaller half-marathon events, typically fielding between 300 and 400 runners each year.

The course follows a route through the park made up entirely of paved park roadways and takes participants through a mixture of parkland areas and nearby residential neighborhoods.

As it is run through a park with plentiful hills, the race course features a number of uphill and downhill stretches, but no major changes in elevation.

The starting and finish lines are in the 950-acre Beaver Island State Park, which lies just on the southern end of Grand Island near the upper part of the Niagara River.

With its beach and marina areas, the park is a local favorite for swimming, boating and fishing, and also has ample nature and hiking trails as well as 18-hole courses for both disc (frisbee) golf and the kind played at Augusta National every year.
