Runners in the Racefaster Half Marathon faced unexpected challenges as heavy rain flooded parts of the course. Participants waded through waist-deep water, with some holding onto railings for support. The New York Post reported four to five inches of rain in Paramus, leading to flash-flood warnings.

Despite the hazardous conditions, the race proceeded with a delayed start. Runners encountered strong currents and dirty water, with some sections deep enough to require assistance. Marijana Dinic described the water reaching her waist to chest height. Organizers did not cancel or reroute the race, despite receiving flood alerts. Read more culture coverage.

Around 250 runners completed the half marathon, but not all participants continued through the flooded sections. Some stopped due to safety concerns, unsure of hidden hazards beneath the water. Organizers have not commented on the decision to proceed with the race. Related: Edmonton Marathon Course Measurement Error Explained.
