Muddy Princess - Long Island, NY | Riverhead, NY, United States

About the Event

Muddy Princess is a 5K obstacle mud run for women!

Our event is for Princesses of all sizes, ages and fitness levels. We don’t focus on fastest times or competitions, we focus on fun so be prepared to run, walk, crawl, climb, slide, balance and laugh your way along our course for an amazing “girls' dirty day out!”

We have no limits on the size of your team, it can be as many Princesses as you can convince to join you for a day in the mud! Please don’t feel excluded if you are entering as an individual, all of our Princesses are part of our Muddy Princess family and there will always be help and support to ensure everybody makes it over the obstacles and crosses the finish line at their own pace.

The venue opens one hour before our first batch. We advise that you arrive 30 minutes before your start time, so you have plenty of time to go through registration.

Spectators are welcome at no additional fee so bring your husband, kids and cheering squad. We have a Village where they can cheer you at the Start and celebrate you at the Finish Line. They can explore the food and drink stalls (subject to availability), or sit and relax while they wait for you to have your fun in the mud. Please Note - We do not have a designated spectator zone along the course. Due to the different set ups at each venue, we cannot specifically keep spectators off the course but, we do ask that you respect the privacy of all our Princesses and please stay in the Village area while waiting for your Princess to return.

We have a Bag Drop ($5 on the day) where you can leave your stuff until you have completed the course.

The minimum age for entry is 7 years young – but please, Moms, little Princesses (up to 13 years old) must be accompanied by a registered, participating adult. Event waivers must be signed by a parent or legal guardian of all Princesses under the age of 18. No waiver, no run, no exceptions.
