O'Shenanigans 5K

Get ready to kick off your St. Patrick's Day celebrations early at the O'Shenanigans 5K, a festive and fast race set for March 7, 2026, in charming Southington, CT. This popular 3.1-mile event, the first of four "O'races" organized by the Hartford Marathon Foundation, is known for its lively atmosphere where costumes are highly encouraged.

The course itself is a highlight, offering a flat and speedy route through scenic rural roads in Southington and Cheshire, including a picturesque stretch along the Farmington Canal Heritage Trail. Runners will pass by local landmarks like the expansive Kurtz Farm before returning to the energetic finish line. Aid stations provide water at the start, mid-point (Mile 1.5), and finish, ensuring runners stay hydrated. Typical race day conditions in early March bring crisp air with highs around 45°F and lows near 26°F, with only an 11% chance of precipitation, making for ideal running weather.

What truly sets the O'Shenanigans 5K apart is the celebratory post-race experience awaiting participants outside Kinsmen Brewing Company. All finishers receive a custom medal and a warm knit beanie, and runners 21 and over can enjoy an ice-cold craft beer from Kinsmen Brewing, paired with fresh, hot pizza from Sauced. The event also caters to younger runners with a Kid's Wee Mile/FitKids Run and supports Southington's Bread For Life food bank through donations. Many runners praise the O'Shenanigans 5K for its excellent organization, enthusiastic volunteers, and strong course support.
