Tomorrow some 36,000 runners are set to lace up their running shoes at the Boston Marathon.

Extra security measures will be in place after last year's bombing that killed three people and injured 264 others.
Police plan to have 3,500 officers on patrol, more than 100 cameras along the route and 50 observation posts set up near the finish line.
Even though the tragedy hit miles away, the effects were felt in Hawaii by local runners.
One runner from Mililani talked about her nervous excitement before her return to Boston.
Emmie Saigusa has trained six days a week and sometimes 22 miles a day. She is one of dozens of Hawaii runners who will run again in the marathon.
"It's to go back and show my support for Boston. For the other runners who were affected by it, and victims who lost their lives. Run it for them," said Saigusa.
When Saigusa crossed the finish line last year, it was a big life accomplishment as her first marathon ever. But as she waited a block away with her fellow runners from Hawaii, she heard the first bomb go off.
"So we were talking story, taking pictures, then all of a sudden we hear the first boom go off and I say what was that?" remembered Saigusa.
Then the second bomb went off, and that's when she said she knew something was wrong.
"The announcer at the finish line stopped announcing. It was complete silence then not too long after that just heard sirens going back and forth," said Saigusa.
This year she believes it will be much safer knowing more security measures will be in place.
"I think it's going to be the safest marathon to run after what happened," said Saigusa.
