We've been following the Bayshore Marathon runners in training for several weeks now.
The race is five weeks away.
Following yesterday's tragedy in Boston, the director of the race says they've already started setting up meetings with law enforcement and area schools, to make sure they have an emergency plan in place.
It's the biggest local running event of the year.
There are 7,400 people registered to run in the Bayshore races, and that's not including their families and friends.
