Rizzoli continually states that panic would ensue causing more deaths and injuries if people found out about murder(s). When actual terror attack happened in 2013, over 5000 people were still competing and race was suddenly ended, diverting runners to 2 locations. Without mass panic and casualties.
Many of the episode titles are also the names of songs; "Born to Run" is by Bruce Springsteen.
Characters throughout the episode question whether the murder is random or part of a larger terrorist attack. They quickly determine that they have a regular, targeted murder on their hands, and someone mentions the fact that the best place for a terrorist attack would be at the start or finish lines to maximize casualties.
Sadly, the 2013 Boston Marathon bombing did feature bombs detonated near the finish line. Since this episode aired almost three years before the real-life bombing, it's possible that the bombers could have gotten the idea for their plot from the show.
