O'Niantic 5K
No blarney, this is a fast and flat 5K! Get in your favorite green gear for a St. Paddy’s themed race that starts and finishes on Methodist Street. Run by the quiet, off-season cottages in the Pine Grove community of Niantic.
Registration includes custom St. Paddy’s inspired reversible knit beanie. Participants 21+ (with ID) also enjoy an ice cold craft beer and everyone enjoys some fresh food to re-fuel, featuring Irish inspired donuts from Flanders Donuts & Bake Shop.
Lucky Challenge – Participate in all four O’races and earn the big bling! Check out the options for virtual/in-person combos to achieve the Lucky Challenge goal. Start with O’Shenanigans, then take on the Courthouse O’Putnam, O’Niantic and either the O’Hartford 5K or 10K. DETAILS
