Terri Bolster was at the 40-kilometre mark, so close to the end, when the bombs went off.

“All of a sudden, I noticed there were people in the crowd, a few people coming towards me,” says Bolster.

A year after the Boston Marathon bombings that killed three people and injured hundreds more, Bolster is packing to finish what she started.

“I think the power of the people who are going to run this year, the emotional power, is going to defeat what happened last year,” she says.

Bolster will be among 36-thousand runners to take part in this year’s marathon.

Increased security measures are in place which includes not allowing any one to use hydration backpacks are carrying bags of any kind. There will also be an increased police presence.

“We’re going to have plenty of our assets and if need be they’ll be rolled in very quickly,” says William Evans, Boston Police Commissioner. “The goal is to make it a safe family day.”

Bolster says she won’t let herself give in to fear.  Instead, she’s ready to cross the finish line for the first time.

“This time it’s not quite so personal…it’s being part of that celebration, taking back the race for the runners.”
