More than 35,000 people are expected to participate throughout the entire weekend of events produced by P3R, a fitness organization that hosts races, events and health and fitness programs throughout the region.
Marathon organizers created a link for the more than 300,000 spectators of neighborhoods to cheer on runners, starting with Downtown near the start at Liberty Avenue between 10th and Grant Street near the Westin Hotel.
The sold-out marathon is 26.2 miles. The UPMC Health Plan half-marathon is 13.1 miles. There is also a half-marathon walking division. The marathon relay has four lengths of varying distances. All races begin at 7 a.m. Sunday at Liberty Avenue near 10th Street, Downtown.
The P3R app gives real-time participant tracking from start to finish. Friends and family can submit a cheer for runners that may be seen on screens along the course. The app features course maps as well as other information and notifications.
