Here's what happened during the 129th Boston Marathon

On a beautiful day for runners and spectators alike, 30,000 athletes traveled along the historic 26.2-mile race route from Hopkinton to Boston.

Familiar names Marcel Hug and Susannah Scaroni won their respective wheelchair divisions, and new victors took the prize for the men's and women's professional races. Kenya's Sharon Lokedi set a new course record in a tight race against last year's winner Hellen Obiri. Fellow Kenyan John Korir took first place in the men's division, becoming the second in his family to be a Boston champion.

In addition to the pomp and circumstance for the 250th anniversary of the start of the American Revolution, this year's Boston Marathon marked five decades since wheelchair racing became an official part of the race.

Here's a look at how the day unfolded:

The sun was shining and spectators joined the daffodils lining the Boston Marathon route.

Amanda Kingsley was waiting to cheer on her husband, Jim O'Donnell, on Heartbreak Hill.

"He felt like this was going to be the hardest part and said to me, 'If you could be at the top of the hill it'd be amazing,' " she said.

It was his first time running a marathon. He raised money to support Spaulding Rehab, where Kingsley works.

Kingsley grew up in Dedham and remembers going to the marathon a lot as a kid, but hadn't been back since moving to New York.

"I forgot just how amazing it is — the human spirit. People are just coming out here altruistically to cheer each other on," she said. "I've been tearful the entire time."

Dean Pappademos, of Somerville, set up near Cleveland Circle to cheer for his girlfriend along with other members of the Boston-based "Rats Run Club."

"Having Beacon Street, and this corner right here by the reservoir loaded with people is going to be super helpful because this is where it's going to get the most difficult for all the runners," he said. "They also just came, at this point, came up Heartbreak Hill. So everyone's legs are going to be really tired, so the screaming is going to be very, very helpful."

A group of seniors from Wellesley College said they cheer on the runners every year. This year, they made signs — some playing on President Trump's new tariffs.

Katherine Li's sign read: "Run like you just found out there's a 200% tariff on walking."

Another read: "Kiss me before the tariff goes up again."

Darryl Carlson was rooting for his daughter, Olivia Carlson, near Heartbreak Hill.

He and his family had signs of her face and he planned to hand her a snack bag when she ran by. It's her first marathon, and she's running it in honor of her mom who passed away from cancer.

Medical officials at the Boston Marathon said there haven't been many serious medical emergencies. Runners have been mostly treated for overheating, cramps and sprains.

Dr. Chuck Morris, medical director for the Boston Athletic Association, said staff have treated a handful of runners for heat stroke — despite the relatively cool weather.

"But the combination of sort of humidity level and the bright sun actually meant that we saw a few patients with true exertional heat stroke, requiring us to kind of cool them in an ice tub."

Kenya's Sharon Lokedi broke the Boston Marathon course record with an unofficial time of 2:17:22 — more than 2 and a half minutes faster than the previous Boston record. She beat two-time defending champ Hellen Obiri by 19 seconds.

“Where she passed me last year, I passed her this year,” Lokedi said with a laugh. “I didn’t even believe. I kept looking back and thinking, ‘Where is she?’ I’m just so grateful to her for pushing me all the way through.”

Fellow Kenyan John Korir won the men's division with the second-fastest winning time in the race's history: 2:04:45. His brother, Wesley, won the Boston Marathon in 2012 — the two are the first pair of family members to win the prestigious race.

“He explained to be tough and believe in yourself,” said John Korir, who finished fourth and ninth in his two previous Boston attempts. “So I believed in myself and I followed his advice.”

Switzerland's wheelchair racer Marcel Hug is now an eight-time winner of the Boston Marathon.

Susannah Scaroni, from the United States, won the women's wheelchair field for the second time after her first win in 2023. She missed last year's race due to an injury; Great Britain's Eden Rainbow-Cooper broke out of the field to win in 2024.

Marcel Hug of Switzerland blitzed to the front of the field to win his eighth Boston Marathon wheelchair title in 1:21:34.

The 39-year-old Hug crossed the finish line in downtown Boston to claim his fifth consecutive win in the race on the 50th anniversary of the first official wheelchair finisher in Boston. Daniel Romanchuk of the United States was second in 1:25:58, followed by Jetze Plat of the Netherlands in 1:30:16.

Hug and Romanchuk broke from the field and stayed tight for about six miles. But Hug opened about a three-minute lead at the halfway mark and began to widen his advantage.

In the women’s race, Susannah Scaroni, of the United States, won her second Boston title, finishing in 1:35:20. Swiss athletes took the next two spots with Cathering Debrunner second in 1:37:26 and Manuela Schar third in 1:39:18.

“I always feel emotional when the national anthem is played," said Scaroni, who won in 2023 but couldn't defend her title last year because of an injury. “And to have ours played on this amazing, historic anniversary gives me goosebumps.”

Scaroni earned her first Boston title in 2023 but wasn’t able to defend it last year because of injury. This time she was dominant late, opening up a 40-second lead 18 miles in, breaking away from Debrunner.

Around 9:30 a.m., Paul Revere rode down Boylston Street to the Boston Marathon finish line — or almost there, as it turned out — proclaiming “the runners are coming" on Monday morning as the world's oldest and most prestigious annual marathon helped celebrate the 250th anniversary of the Revolutionary War.

Reenactors on horseback, accompanied by a fife and drum playing “Yankee Doodle,” helped start the festivities and add a bit of levity when Revere's horse was spooked by the finish line decal on the street and stopped. The actor portraying the colonial silversmith and patriot had to hop off and walk the last few steps himself.

After reading a proclamation, Revere gently tugged the horse the rest of the way before heading off to more ceremonies commemorating his midnight ride on April 19, 1775, to warn the people in Lexington and Concord that the British were on the march.

A group of about 40 Massachusetts National Guard members crossed the starting line around 6 a.m. to launch the world's oldest and most prestigious annual marathon.

Race Director Dave McGillivray said it's a highlight of the day to see them out on the course each year.

“We appreciate their service, and just the fact that it's Patriots’ Day gives it even more meaning,” he said.

It's the 50th anniversary of the first wheelchair race in the Boston Marathon, pioneered by Bob Hall who is serving as co-grand marshal this year.

“In Boston, we love celebrating anniversaries and the milestones that got us here,” Boston Athletic Association President Jack Fleming said last week. “What a revolutionary idea that was: wheelchair racing in the 1970s.”

The weather is expected to be ideal for runners and spectators alike today. Meteorologist Danielle Noyes says temperatures start in the 40s with sun overhead in the morning. It'll warm up to the high 50s and even 60 later in the day as more clouds move in. Here's a full forecast.

The wheelchair racers will hit the finish line starting around 10:15 a.m., and men's elite division will start to reach Boylston Street around 11:30 a.m.

It's Patriots' Day, a state holiday for Massachusetts commemorating the battles of Lexington and Concord that lit the Revolutionary War. Here's what's open and closed in the state today.

There's a special 250th anniversary ceremony at the finish line this morning in Boston at 9:30 a.m. The National Lancers, a ceremonial cavalry squadron based in Framingham, will ride on Boylston Street to commemorate the 250th anniversary of Paul Revere’s ride at the start of the American Revolution. Revere set off from Boston to warn the colonists in Lexington and Concord that the British regulars were on the march.

The Red Sox play the White Sox at Fenway today at 11 a.m.
