The Sloppy Cuckoo 12 hour challenge takes place at Pennypack Park, a beautiful oasis within the city of Philadelphia. We designed a 6.55 mile loop that is very runnable , incorporates geourgeous views of Pennypack Creek, offers enough variety to keep you occupied for the entire day and is just easy enough to cover long distances.
This is a great format to see how far you can go. Did you ever cross a finish line and thought: “ I could have ran all day”? See how far you can go, or run a distance that you never conquered before because a time limit prevented you from doing so. We have top-notch fully stocked aidstations staffed by local ultra runners and 2 professional chefs at the finish line taking care of you. Every runner finishing 26.2 or more will receive an unique German weatherhouse with a wooden plaque indicating your overall mileage that day and our cuckoo whistle finisher "medal" certainly is a conversation piece. Enjoy the cameraderie on the course with a bunch of cuckoo ultra runners.
