Get ready for the ultimate "girls' dirty day out" at the Muddy Princess - Boston, MA, hitting Kimball Farm in Haverhill, MA, on Sunday, June 21, 2026. This isn't just a 5K run; it's a celebration of female bonding and empowerment, focusing on fun and teamwork rather than competition. You'll tackle over 18 exhilarating obstacles designed to have you running, walking, crawling, climbing, sliding, and laughing your way through a challenging yet incredibly enjoyable course. Expect to wade through mud and water, conquer ropes and tire towers, test your balance, and slide down embankments alongside your fellow princesses. Should an obstacle prove too challenging, you're always welcome to bypass it and continue your muddy adventure.

The Muddy Princess is renowned for its vibrant, supportive atmosphere, welcoming women and girls aged 7 and up to embrace their inner princess – tutus, tiaras, and glitter are highly encouraged. As you navigate the course, stay refreshed with at least two water stations strategically placed along the route. After crossing the finish line, celebrate your accomplishment at the lively Village area, where spectators can cheer you on and enjoy food and drink stalls. A rinse-off station will be available to help get the majority of the mud off.
