Monday marked the 121st Boston Marathon, but for one out-of-town spectator, it was his first time taking part in the famed event.

Michael Roth made the trip from Chicago to cheer on a friend, and he basked in the clear blue skies and temperatures that hovered in the 70s.

Thousands of fans like Roth clapped, waved signs and shouted words of encouragement to the 30,000 runners who made their way along the 26.2-mile course.

One of those runners was Kathrine Switzer, who in 1967 became the first woman to officially register — and run — in the race. Fifty years late she repeated that feat, wearing the same bib number, 261, she wore the first time. Switzer finished the marathon in 4:44:31, and her bib number will be retired from the Boston Marathon, race officials said.


While the day’s warm weather was a joy for spectators, it was another obstacle to overcome for runners, like the grueling ascent around mile 20 known, as Heartbreak Hill.

Before 3 p.m., a few hours into the start of the event, Boston EMS reported that more than 1,200 runners had received medical services at stations along the route, at the finish line and at area hospitals. In Newton, where the race course travels, the local fire department used water misting stations to help keep marathoners cool through the tough hills.

Despite the unexpected heat, runners streamed across the finish line. The elites athletes, of course, led the pack.

Edna Kiplagat of Kenya won her first Boston Marathon with a time of 02:21:52, trailed by Rose Chelimo of Bahrain who finished about a minute later. Third place in the women’s race went to American Jordan Hasay, who finished in 2 hours and 23 minutes. This was the first marathon of Hasay’s career, and she set a record for the fastest debut time ever for an American woman.

In the men’s race, Geoffrey Kirui of Kenya took first place, winning with a time of 02:09:37. American Galen Rupp followed in second, clocking in at 02:09:58. Suguro Osaka of Japan came in third, with a time of 02:10:28.

Among the notable runners was a fan favorite from a different sport. Doug Flutie, former New England Patriots quarterback and Boston College star, crossed the finish line to complete his third Boston Marathon.

Mayor Marty Walsh tweeted updates from the course throughout the day. “Boston is lucky to be the home of the greatest marathon in the world,” he tweeted at one point.

Update: 4:45 p.m. Doug Flutie, former New England Patriots quarterback and Boston College alumnus, crossed the finish line of his third Boston Marathon. The Doug Flutie, Jr. Foundation for Autism, which he named after his son, is an official charity partner of the 2017 Boston Marathon.


Update 4:25 p.m.: Fifty years after her first Boston Marathon, in which she almost got tackled out of the race, Kathrine Switzer has one again completed Boston. This time, the now 70-year-old clocked in at 04:44:31. Switzer is seen as a pioneer after she signed up for the Boston Marathon in 1967 under her initials, making her the first official female ever registered in the race. 


Update 3:15 p.m.: It's been pretty warm out on the marathon course today, which Chris Troyanos, the Boston Marathon's medical services coordinator, previously told Metro could cause some health problems for runners. The Boston Herald is reporting that by 3 p.m., about 1,600 runners have received medical treatment for overheating, exhaustion and dehydration. The marathon has about 30,000 competing today. It's still nothing like the 2012 race, when temperatures climbed to 86 degrees and more than 4,000 runners were treated by medical services, many with body core temperatures of 108 degrees, Troyanos said.


Update 2:20 p.m. Boston Police Commissioner Bill Evans ran the Boston Marathon on Monday for the first time since the 2013 bombing. The 58-year-old commissioner finished with a time of 3:50:30, marking the completion of his 52nd marathon. He has run Boston 19 times.

Update 2:10 p.m. There are a lot of law enforcement officials out on the course today protecting both spectators and runners, and that means four-legged law enforcement as well. The New York Police Department chief of counterterrorism shared this tweet of a furry K9 bomb squad member on patrol. 


Update 1:35 p.m.  Even the Red Sox wanted to show their Boston pride on Marathon Monday. Players are sporting "Boston Strong" jerseys Monday for the annual Patriot's Day game. This year they are playing the Tampa Bay Rays.

Update: 1:10 p.m. Camaraderie is always a huge part of the Boston Marathon, especially with about 30,000 runners sharing the course this year. Gov. Charlie Baker shared a perfect example of that closeness and good sportsmanship: two runners holding up a third, helping in the last paces before the finish line.


Update 12:48 p.m.: Marathon spectators are out in full force, lining the streets in folding chairs and carrying creative signs as a way to motivate runners. 



Update 12:22 p.m.:  Gov. Charlie Baker presents the Boston Marathon trophy to women's winner Edna Kiplagat as the Kenyan anthem played in the background and her children stood beside her.

Update 12:15 p.m.: Geoffrey Kirui of Kenya crosses the finish line, winning his first Boston Marathon with a time of  2:09:37. Kirui is 24 years. Galen Rupp of the U.S. took second place soon after with a time of 2:09:58. Suguru Osako of Japan came in third with a time of 02:10:28.

Update 11:54 a.m.: Edna Kiplagat of Kenya crosses the finish line, winning her first Boston Marathon with a time of 02:21:52. Rose Chelimo of Bahrain trailed Kiplagat by about a minute, completeing the race with a time of 02:22:51. Jordan Hasay, an American, took third with 2:23:00, the fastest marathon debut time by an American woman.

Update 11:46 a.m.: Kenyan racer Edna Kiplagat is 5:04 ahead of all other elite women racers in the 121st Boston Marathon. She's rounding mile 23 and spectators at the finish line in Copley Square are already lined up, waiting to cheer on Kiplagat and the rest of the runners. The elite men racers are steps behind the women, rounding mile 20, according the Boston Athletic Association.

Update 11:40 a.m.: Boston Marathon bombing survivor Marc Fucarile has crossed the marathon finish line. In 2013, Fucarile was at The Forum restaurant on Boylston Street with a group cheering on their friend who was running when the bombs went off, according to MassLive. He lost his right leg and sustained burns on 90 percent of his lower body.


Update 11:15 a.m.: The fourth — and final — wave of runners is lining up at the starting line in Hopkinton. This wave includes Kathrine Switzer, the first woman to officially enter and finish the Boston Marathon.

Switzer entered the race 50 years ago in 1967 using her intials. A race official tried to physically pull her off the race course. The scene was captured by local media at the time. It proved to Switzer how important it was for her to finish the race, which she did. It would be five more years before women were officially invited to race in the Boston Marathon, but Switzer's actions during the 1967 race are remembered as the trailblazing effort that propelled women into competitive running alongside men. Switzer, now 70, has since completed 39 marathons and authored a book about her experiences.

Update 10:55 a.m.: Though some athletes have already completed the marathon's 26.2 miles, others haven't even started the race yet. There are 30,000 people running the Boston Marathon this year and many of them are still milling around the Athelte's Village in Hopkinton, waiting for their waves to start.


Update 10:50 a.m.: The Boston Athletic Association announces the winner of the women's push-rim: Manuela Schar of Switzerland. This is Schar's first Boston Marathon win and she set a new course record of 1:28:17.

Update 10:45 a.m.: Boston Mayor Marty Walsh along with the five families who lost loved ones in the 2013 Boston Marathon bombings announced today the artist who will honor the victims and survivors with installations along Boylston Street.

Sculptor Pablo Eduardo was chosen unanimously by the families to design the markers that will be placed on the two bombing sites on Boylston Street. Eduardo graduated from The School of the Museum of Fine Arts and Tufts University and he will work in collaboration with the families, the City of Boston and the Boston Art Commission to design, construct and install the memorial, the mayor’s office said in a release.

"We will never forget the events of April 15, 2013," Walsh said in a statement. "Together, these memorials will create a place for people to connect with each other, and to reflect. The result will be a testament to the spirit and resiliency of the people of Boston, and a way to honor those we have lost, and those who are still healing."

The art installation at the bombing sites is scheduled to be complete by April 2018.

"It is humbling to have been chosen to create a work of art that will honor the victims of the 2013 Boston Marathon attack," Eduardo said in a statement. "Art is a powerful vehicle for remembrance and healing, and my goal is for this art to embody the spirit of those we lost and the spirit of the city they loved."


Update 10:40 a.m.: The Boston Athletic Association announces the winner of the men's push-rim: Marcel Hug. This is Hug's third straight Boston Marathon win. Today he set a new course record of 1:18:04

Originally published at 10:30 a.m.: Marathon Monday is in full swing in Boston, as racers in the 121st annual Boston Marathon are well on their way to the finish line.

Sunny skies and warm temperatures edging into the 70s greeted runners at the starting line in Hopkinton as the first wave of racers – the mobility impaired – took off at 8:50 a.m. The elite women racers started at 9:30 a.m., followed by the elite men at 10 a.m.

Here is the complete list of times when runners push off for the 2017 Boston Marathon.

– 9:17 a.m. — Men’s push-rim wheelchair start
– 9:19 a.m. — Women’s push-rim wheelchair start

More than 30,000 runners will participate in the 26.2 mile race that ends at Copley Square in Boston. The Boston Athletic Association, which organizes the annual marathon expects up to 500,000 spectators could turn up to cheer on runners.

The bulk of the runners will be passing through the finish line between 10:41 a.m. and 3:04 p.m., the BAA said, though times are subject to change.

Elite runners could finish the race in as little as two hours and ten minutes – Galen Rupp, fresh off a bronze medeal at the Rio Olympics in the marathon with a time of 2:10:05 looks to be America's best bet to bring home a win, but most runners will take about five hours to complete the 26.2-mile Boston Marathon.
