Event Description

Welcome to the Great South Bay 5K & Fun Run, hosted at the beautiful and historic Heckscher State Park in East Islip, NY!

Our mission is to bring the Suffolk County community together for a premier day of fitness, family fun, and environmental awareness. This year, we are proud to support local green initiatives and state park preservation efforts across the South Shore.

An event of this scale is only possible through the generous support of our local business sponsors. We would like to recognize and thank the key organizations helping us bring this event to life:

Suffolk Drain and Sewer: Serving as our official course safety and logistics sponsor, they keep Suffolk County moving with 24/7 emergency drain cleaning, main sewer line clearing, and root-removal services.

Fusion MMA & Kickboxing: Providing our pre-race warm-up and stretch zones! Located in Port Jefferson Station, they are the area's top destination for elite fitness, kickboxing, and martial arts training.
