Students and residents in the Burlington area gathered on the waterfront to run and walk in support of the victims of the Boston Marathon tragedy April 20.The run/walk was a part of a recent global movement ?Get Moving for Boston.? That has people running or walking wherever and whenever they chose in support of the victims of the tragedy. Ryan Polly, a Williston resident, helped organize the event. Polly attended the Boston Marathon this year, and although he was unharmed, he said he was forever impacted emotionally, according to the Get Moving for Boston website. ?I had scheduled a post-run party on Saturday to celebrate my accomplishment,? Polly said. ?I can no longer celebrate. Instead, I will now run in memory of those people who were not as lucky as I am.?People in 31 states and six countries vowed to participate in a virtual run/walk in support of the cause, according to the website.?The Boston Marathon tragedy really hit close to home for a lot of people,? first-year Rachel Rhodes said. ?It?s no wonder so many people came out to support the victims and their families.?Participants were also encouraged to donate to either One Fund, a charity established to raise money for the families of victims, or to Massachusetts General Hospital which has an Emergency Fund to help care for patients. 4 p.m. at Waterfront Park near the ECHO Lake Aquarium and Science Center, crowds of participants gathered to run on the bike path. ?In terms of people I?d say we had a few hundred,? Bob Fishel said on the day of the event in Burlington. ?In terms of money I?d say a few hundred.?After counting race participants and their donations, there were over 500 people present to walk/run and $10,300 was raised for the charities.First-year and Boston resident Sophie Stoker-Long said she was touched by the event. ?It was really touching to see how many people were there, and to see all those people take off and know it was for my city,? she said.
