About 150 participants ran or walked the three-mile, downtown route as a show of unity against the fears stoked by terrorism. Donations were collected to benefit the Lawrence Police Foundation. Run organizer Jon King said that he chose the foundation after being inspired by the heroism of first responders at the scene in Boston. Nick Krug/Journal-World Photo
