With just three weeks to go until the Boston Marathon, hundreds of runners took to the course Saturday to get in one final big run.
It's not the normal starting line in Hopkinton, Massachusetts, but three bus-loads of runners left Ashland and ran all the way to Boston's Bolyston Street as if it were Marathon Monday.
"You literally gotta get the miles in," said Dan Lionetta, one of the runners training Saturday.
This is Lionetta's fourth time running the race, and he says he can't get enough it.
"I keep telling myself I'm not and just keep turning back up, it's too much fun," he said.
Finding time to enjoy the race is important, because for many of these runners, the training can be very intense.
When these legs get tired, volunteers are stationed along the course with water and plenty of support.
