Muhammad Junaid, who works as an anchor for Geo News, became the first Pakistani journalist to run the Boston Marathon on Monday.
Junaid completed the race in 3 hours 36 minutes 38 seconds.
The 127th Boston Marathon featured nearly 30,000 athletes from more than 100 countries.
“Time has come. I may be the one running the Boston Marathon today but it’s not for me only I am running for all of you and this was never possible without my people, the best people. Only one Junaid in 30,000 runners today, thank you all and see you at the finish line,” Junaid tweeted before the marathon.
The legendary Boston Marathon course starts in Hopkinton and ends on Boylston Street in Boston, Massachusetts, and is spread over 26.2 miles.
Eliud Kipchoge, the world’s greatest marathoner, was part of the Boston Marathon for the first time, meanwhile the women’s field also included champions.
The Boston Marathon was among the six World Marathon Majors this year, following the Tokyo Marathon, which was held in March.
This year also marks the 10-year anniversary of the Boston Marathon bombings that took place near the finish line, which led to three people being killed and left more than 281 injured.
The runners also paid tribute to the victims of the bombings with traditional signs and memorials.
Evans Chebet and Hellen Obiri stormed to victory in the men's and women's races to complete a third straight Kenyan double in the long distance-running showpiece.
Obiri, who only raced a marathon for the first time in New York last November where she placed sixth, kept her composure in a hard-fought race to win in 2hr 21min 38sec.
Ethiopia's Amane Beriso was second in 2:21:50 while Israel's Lonah Salpeter took third in 2:21:57.
In rainy, cool conditions, defending men's champion Chebet upstaged world record-holder Eliud Kipchoge to become the first man to defend the Boston title since Robert Kipkoech Cheruiyot's 2006-2008 hat trick.
Chebet finished in a time of 2hr 5min 54sec, with Tanzania's Gabriel Geay second in 2:06:04, and Chebet's training partner and fellow Kenyan Benson Kipruto third in 2:06:04.
