Runners and spectators will see additional security and new security checkpoints at the finish line of today’s 42nd annual Chevron Houston Marathon.   The new checkpoints and enhanced security were added in lieu of the April 15, 2013 Boston Marathon Bombing.  During the Boston Marathon two pressure cooker bombs exploded, killing three people and injuring hundreds.  

Wade Morehead is the Houston Marathon Committee's Executive Director.  According to Morehead everything from strollers to bag packs and large purses will be checked.  Morehead encourages spectators who want to attend this year's event without all the hassle to" leave your valuables and larger bags at home if you want to walk in without stopping.”  He encourages runners to only bring their race-issued gear check bags. Twenty-five thousand runners are registered to participate in the Chevron Houston Marathon. 

Of the registered participants, four of the top five finishers from the 2013 USA Half Marathon Championships are expected to cross the finish line in Houston.   Some other participants the Houston Marathon Committee lists as notable runners to watch:
