Why do you run Broad Street? Amber's inspiring story

In the summer of 2010, Amber Rosenberry, then 30, was walking through her Philadelphia neighborhood when she tripped over a crack and fell into the street, just as a delivery truck was driving by.

The rear wheels crushed her right arm. After repeated surgeries, it was encased for months in a metal brace.

These were dark, depressing days for a young woman new to Philadelphia. Her Washington Square West neighbors rallied around her. Local salons took turns washing her hair. A coffee shop would open cans of food for her.

She set goals to motivate herself, small ones at first:

"Write an entire text message with my right hand."

"Eat a bowl of popcorn with my right hand."

The last goal: "Finish the Broad Street Run."

At the starting line, Amber wasn't sure she could run 10 miles. "I knew that my house was around mile six," she said. "I figured if I had to stop… I could."

Amber didn't stop at mile six, or at mile eight, Methodist Hospital, site of her surgeries. "I didn't realize the hospital backed up to Broad Street," she admitted. "At that moment, there was no question I was finishing that run."
