Garden State 10 Miler and Cookie Chase 5K

Get ready to kick off your spring running season at the Garden State 10 Miler and Cookie Chase 5K, returning on Sunday, March 22, 2026, in scenic Colonial Park, Somerset, NJ. This event has earned its reputation as "NJ's Favorite Distance Race!" and promises an engaging experience for runners of all levels. Choose your challenge from the main 10-mile race, the delightful Cookie Chase 5K, a 10-mile relay for teams, or conquer both with the Half Marathon Challenge to earn an exclusive "Challenge Accepted" medal. A Youth Fun Run ensures the whole family can join in the excitement.

The courses wind through the beautiful 685-acre Colonial Park, offering picturesque views along the historic Delaware and Raritan Canal and the Millstone River, with broad lawns, ponds, and horticultural displays providing a refreshing backdrop. Described by some as "the fastest ten miler in the tri-state area!" and a "great course," runners can expect a well-marked, closed-off route with a generally fast profile, including a slightly downhill start. While you might not find huge crowds of spectators, the atmosphere is celebrated for its community spirit and a clever, annually changing New Jersey theme. Typical race day conditions in late March bring highs around 53°F and lows around 33°F, with a modest 14% chance of precipitation, offering pleasant running weather.

Beyond the run, participants rave about the unique perks: 5K finishers are rewarded with a delicious cookie from Insomnia Cookies, and all 10-miler finishers receive a medal. The event also boasts prize money for top finishers in both distances and awards for the best costumes in the 5K, adding a festive flair. Packet pickup is conveniently available on Friday and Saturday at Road Runner Sports in North Brunswick, with race day registration also an option at Colonial Park. Moreover, your participation supports a great cause, as event proceeds contribute to need-based scholarships for local Franklin High School graduating seniors.
