Thousand Islands Half Marathon, 10K & 5K

Take in the famous views of the Thousand Islands and Thousand Islands bridge. Once again, we will be offering the 5K on Friday evening at the Thousand Islands Winery in Alexandria Bay.  On Saturday, we will offer the 10K and Half Marathon on Wellesley Island along with the post-race festivities and awards ceremony. If you are feeling ambitious, you are more than welcome to consider the Island Double (5K & 10K) or the Island Super Double (5K & 13.1M). This event is part The Get Fit Half Marathon Series. 

For 2025 we are returning to the Lake Course Executive Club House (21496 Club House Dr.) for the start/finish for Saturdays Half Marathon & 10K similar to years 2020-2023.

Great views, great courses...always best swag plus we get to help the great people of Alexandria Bay as well as the ACS Booster Club!
