Thomas and her friends all were able to escape injury, but Thomas is one of many runners like, Paul McRae who are returning home to Jacksonville with tales to tell of the destruction in Boston.

"Never could doubt someone could do something like this but it's sad. It means marathons, big marathons are going to be changed ," said McRae.

McRae wasn't there for the explosion Monday, he had already finished the race and was stunned when he found out the finish line he had just crossed had turned into a disaster scene.

"Literally about an hour later, 30 minutes people were starting to text my phone, I thought it was terrible joke at first and I turned on local news and that's when I obviously realized it wasn't a hoax," said McRae.
