The event drew out runners from 50 different countries and regions, and roughly 60,000 spectators who came out to cheer for friends, family and strangers.
Immediately after the bombings in Boston, the Toronto Marathon posted a statement on their website to inform the public they're working closely with the police to ensure the safety and security of all participants and spectators. Glassman said officers were patrolling the course as usual, but couldn't speak to specifics due to security concerns.
But safety was the last thing on many runners' minds on Sunday. Shirley Steele said the recent events have just motivated her more to qualify for the Boston Marathon next year.
"I think having it happen has made me want to run it that much more, hopefully I'll make it there next year," she said.
Another seasoned runner, Dave Bolan, said he tries not to let potential threats like this hold him back in life.
