Special Guest Announcement: Coach Derick "Ringo" Adamson at the Mischief on the River 5K!

We are thrilled to announce that two-time Olympian and legendary running coach Derick "Ringo" Adamson will be joining us for the Mischief on the River 5K!

Whether you're lining up at the starting line to set a personal record or cheering from the sidelines, don't miss the chance to meet one of the most accomplished and inspiring figures in distance running.

About Coach Derick "Ringo" Adamson

Two-Time Olympian: Derick represented Jamaica on the world's biggest stage, competing in the men's marathon at both the 1984 Los Angeles Olympics and the 1988 Seoul Olympics. He also represented his home country at the 1990 Commonwealth Games.

Back-to-Back Philadelphia Marathon Champion: A local legend in distance running, "Ringo" achieved back-to-back victories at the Philadelphia Marathon in 1984 and 1985. His winning time of 2:16:39 in 1984 set a Jamaican national marathon record, and he dominated the field again in 1985, crossing the finish line over 5 minutes ahead of the nearest competitor.

Multi-Time Coach of the Year: Beyond his iconic competitive career, Adamson has dedicated decades to developing collegiate athletes. He earned regional Coach of the Year honors at Gloucester County College in 1985 and went on to be named the NJAC (New Jersey Athletic Conference) Women's Cross Country Coach of the Year four times (2008, 2009, 2011, and 2012) before becoming the head coach for Rowan University's women's cross country program.

Come out to meet Coach Ringo, get inspired by an Olympic marathoner, and enjoy a fantastic day of racing along the river!


Want to challenge yourself and potentially win a free race entry to our 2027 Mischief on the River 5k?!

Well all you have to do is run "Naked!"

NAKED?! You might be thinking. Well have no fear you will be fully clothed but you'd be running without a watch or phone.

You will have a chance the morning of race day to submit your estimated finish time, you will then be asked to run the race "naked" no watch, no phone, and no pacer.

The runners that finish closest to their estimated time in all three gender categories will win free entry to the 2027 race!

Let's make some "naked" mischief out there!
