30,000 competitors are expected to take part in Saturday's Rothman 8k and Sunday's Philadelphia Marathon races.

Nearly two-thousand people began running on the Ben Franklin Parkway Saturday morning for the annual Rothman Institute 8K.

It's the precursor for Sunday's main event, the Philadelphia Marathon.
