In the heart of Fairfield County, Connecticut, ultrarunners are invited to experience the inaugural Great Lawn Backyard Ultra on November 14. This unique race challenges participants to push their limits hour after hour as they navigate an enchanting loop through Cranbury Park. The course is a scenic 4.2-mile circuit that winds through historic estate grounds, lush woodlands, and meticulously maintained park paths. Each lap begins exactly at the top of every hour with runners alternating directions every four hours for fresh terrain and strategic challenges. The route offers classic late-autumn New England scenery, crisp air, and rolling elevation changes that keep a steady pace achievable. The central aid station is conveniently located right at the start/finish line in Cranbury Park, providing essential hydration and nutrition after each lap. Runners can rely on fully stocked supplies of water, electrolyte drinks, warm food options, and hot beverages as temperatures drop into the night. Personal crew setups are permitted within a designated basecamp area to support runners between laps. The race adheres strictly to backyard ultra rules: at exactly 60 minutes past each hour, a bell signals the start of the next lap. All participants must be in position when the bell rings; no late starters will be allowed. Runners have an entire hour to complete their loop and prepare for the next round. The event continues until only one runner successfully completes a lap under the hour limit, securing victory. Registration is recommended early as field size is limited for this inaugural year. November weather in Connecticut can be unpredictable—expect brisk temperatures, wind, and potentially freezing conditions at night. Runners should come prepared with multiple layers of warm clothing, thermal change clothes, heavy-duty jackets, gloves, beanies, and reliable headlamps equipped with extra batteries. This event promises an unforgettable ultrarunning experience set against the picturesque backdrop of Cranbury Park in Norwalk, Connecticut.
