Mean Streets, Lawrenceville

For this 5K race, a normally tame park or other venue is transformed into Mean Streets, an urban-themed obstacle course. In the Construction Zone, participants navigate over and under traffic barriers of different heights followed by a dive into a trash-filled dumpster. After bypassing the dumpster zone, runners test their stamina as cat burglars, scrambling through first-floor windows and trespassing through backyards. They barely touch ground before scaling upward once again on the Time-to-Climb portion of the course, which features a Jason Bourne-esque run across the rooftops. Finally, contestants climb out a window and onto the fire escape, swinging across an 8-foot ladder to reach the finish.
