An estimated 40,000 people are filling Broad Street this morning from

Somerville Avenue in Logan to South Philadelphia's Navy Yard for the

33nd annual ten-mile Blue Cross Broad Street Run, which began at 8:30

a.m. The race, one of the most popular ten-mile road races in the

nation, sold out in five hours – over a quarter of the city's

population registered.

The route from North to South Philadelphia, named by Runner's World as

one of the fastest ten-mile courses in the country, is lined with

water stops, aid stations and live entertainment – last we heard

around City Hall, there were some serious stadium rock jams blaring.

All pledges and donations benefit the American Cancer Society.
