This year’s Boston Marathon took place on April 18, marking the third anniversary of the terrorist bombings, which left 3 dead and an estimated 264 injured. The 2016 Boston Marathon was heavily guarded by police and emergency personnel who were trained by public safety agencies leading up to the event.

The race begins in Hopkinton, Massachusetts, and goes through the suburbs of Ashland, Framingham, Natick, Wellesley, Newton, and Brookline and finishing on Boylston Street in downtown Boston. Thirty thousand people registered for the race this year, and over a million people stood on the sidelines to watch and cheer on the runners.

Starting off the events were the mobility-impaired runners. One of the runners included bomb survivor Adrianne Haslet, who lost a leg in the attack. She hadn’t competed in the marathon since that fateful day in 2013, and is one of the 21 survivors who ran in the marathon this year. The wheelchair division followed, ending with American Tatyana McFarren winning for the fourth year in a row. Marcel Hug of Switzerland placed first in the wheelchair race for the second consecutive year.

While most Olympic runners are focusing on this year’s races in Rio instead of the Boston Marathon, two runners from Ethiopia have swept the elite division once again. Atsede Baysa finished first in the female division with an unofficial time of 2:29:19, and Lemi Berhanu Hayle won the male division with a time of 2:12:45.

Despite the horrible events that happened in Boston three years ago, this marathon still popular, and people still line the streets of the city to support the runners.
