A moment of silence was held to honour the victims of the Boston tragedy before thousands of people participated in a race along Yonge Street on Sunday morning.

More than 7,500 runners and walkers were expected to participate in the annual Toronto Yonge Street 10k race, which was held under tighter security due to the deadly Boston Marathon bombing.

In response to last Monday’s bombing, organizers of the Yonge Street 10k met with Toronto police and city staff to review the security measures for the 27th annual race.

Race director Alan Brookes said volunteers were advised to be vigilant and look for bags left on the ground along the route, as part of a "no-clutter" policy.

Runners who left their gear with volunteers as they participated in the race were given clear plastic bags to hold their belongings.

Toronto police Staff Sgt. Mike Perreault told CP24 reporter Jackie Crandles that more police officers were assigned to this year’s race than last year’s event.

Brookes, who attended the Boston Marathon, described the mood of the runners before the start of Sunday’s race.

“We’re still in shock and perhaps a little disbelief at the tragic events on Monday,” Brookes told CP24. “I think we saw this week the spirit of the marathon and running would not be diminished. While we are still very much in shock and sadness, the whole community, globally, seems to have come together in shows of support and it’s wonderful that we have the opportunity in Toronto.

“Running is about joy, about achievement, about happiness, and I think this is why we were especially shocked with the events on Monday,” Brookes said.

As a tribute, runners wore a special Boston race bib as they made their way along the downhill course, starting on Yonge Street, just north of Eglinton Avenue.

Participants eventually crossed the finish line on Fort York Boulevard after cutting through downtown Toronto.
