The Boston Marathon is looking to make new memories this year, with some 36,000 participants.
They're picking up the numbers that will mark their finishing time. And they're as motivated as ever for Monday's race.
Some runners laced up a couple days early for the Boston Athletic Association 5K run and memorial walk.
It paid tribute to the victims of the 2013 Marathon Bombings.
And many participants had a personal reason for attending.

"It's the least we can do. They were always a family we admired long before the tragedy."
Mayor Martin Walsh was there, supporting a resilient Boston.

"Just seeing the strength and courage that people have is just incredible. There's a great energy in Boston today."
A heavy police presence is planned for Monday's marathon. And everyone will face new restrictions, including a ban on backpacks.
But experts say this year's race could bring a sense of closure for some who were affected by the 2013 bombings.
