About 36,000 people are expected to run the Boston Marathon on Monday.
Thirty-two Acton residents registered to run the race. Check out the full list in the charts above.
The marathon is expected to be an emotion-filled event following last year's bombings. Officials have instituted a host of security measures. And unlike in previous years, unregistered "bandit" runners will be prohibited.
