Staffing shortages mean the extra Port Authority of Allegheny County service that Pittsburgh Marathon runners and spectators have enjoyed in the past might not be available this weekend as the races return for the first time in two years.

“In previous years, Port Authority has provided extra service to assist runners and spectators traveling to the marathon start line and to connect to detoured buses,” spokeswoman Melissa Rubin said in a statement. “Due to staffing and hiring challenges, unfortunately this extra service cannot be guaranteed.”

In previous years, Port Authority often increased light rail and other services to accommodate thousands of runners and spectators. This year those numbers are expected to be around 40,000 and 300,000, respectively.

“We encourage riders traveling to the marathon and related events prior to the start of regularly scheduled Sunday service to consider alternate transportation if necessary and to allow for additional travel time,” Rubin said.
