Thousand Islands Half Marathon, 10K & 5K

Take in the famous views of the Thousand Islands and Thousand Islands bridge. Once again, the 5K will be offered on Friday evening at the Thousand Islands Winery in Alexandria Bay.  On Saturday, the 10K and Half Marathon will run 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 previous years.

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!
