Along with road closures, there will be almost 40 Pittsburgh Regional Transit bus routes detoured as part of the day's festivities. 

The 5K steps off at 8 a.m. Sunday morning in Oakland on Fifth Avenue and Atwood Street, followed by the 10K kicking off at 9:30 a.m. in Frick Park at Beechwood Boulevard. 

The race began in 1977 when former Pittsburgh Mayor Richard S. Caliguiri wanted to establish a community fun run and in the years since it began, nearly a half-million people have been part of the race and it remains one of the city's longest-running races. 

This year, it's expected to draw 10,000 runners.
