A cross-country relay is running through Pittsburgh.
"One Run For Boston" started late last month in Los Angeles and will reach Boston on Sunday.
On Tuesday, about 30 runners took part in a local leg on the North Shore.
It is a fundraiser for victims of the Boston Marathon Bombings.
The goal is to raise $1 million.
