Margarita Half Marathon & 5K

Get ready to shake up your spring at the Margarita Half Marathon & 5K, set for May 17, 2026, in scenic Greenland, NH! This festive event invites runners of all levels to experience the charming New England backroads of Greenland and Newington, promising good vibes from start to finish. Runners can choose between the challenging yet rewarding 13.1-mile half marathon or the spirited 5K distance. Typical race day conditions in mid-May offer ideal running weather, with highs around 67°F and lows around 47°F, alongside a mere 17% chance of precipitation.

The course for the Half Marathon is described as gently rolling, scenic, and relatively easy, winding through a Portsmouth avenue neighborhood before venturing onto Newington Road with picturesque views of the Great Bay Estuary and pastoral farm fields. As you traverse into Newington, you'll find serenity in the Great Bay National Wildlife Preserve and pass by centuries-old stone walls and cemeteries, culminating in views of the Newington Historic District at the turnaround. The 5K shares the initial scenic miles before reaching its own finish. Aid stations are well-stocked and plentiful, with five points on the half marathon course (miles 2.1, 4.4, 6.2, 8.8, and 11.9) and one at mile 2 for the 5K, all offering Gatorade and water to keep you hydrated.

Beyond the miles, the Margarita Half Marathon & 5K is renowned for its vibrant atmosphere and unforgettable post-race party. Race production is consistently well-organized, with friendly and helpful volunteers creating an encouraging environment. Finish strong and celebrate your accomplishment with a complimentary margarita (for runners 21+), delicious tacos, and refreshing beers from Smuttynose Brewing Co. Every participant also receives premium race swag, including a vibrant technical shirt (short-sleeve for 5K, long-sleeve for half marathon) and a custom finisher medal, making this an event that truly delivers on its promise of fun, scenery, and celebration.
