Boston Marathon: Champions crowned on soggy Marathon Monday

Henry Richard, the brother of Martin Richard, the youngest person killed in the attacks 10 years ago, finished his second Boston Marathon.

Henry ran with Team MR8, which included several of Martin's former classmates.

"It was a very emotional day, being the 10-year anniversary, but running as one, running as a team really kept us going the whole way," Henry Richard said.

"It's a very emotional race for me, for my family, for my friends, Martin's friends, so definitely thought of him the whole way." 

Ten years after Martin was killed in the 2013 bombings, his friends are finally 18, old enough to run.

"They are really happy," said Jack Burke, Martin's friend. "Along the race we were kind of like fan favorites and it's super heartwarming. People like know the name and know what we stand for and it's honoring his legacy."  

From a window above Boylston Street stood a quintessential symbol of "Boston strong", marathon bombing survivor Heather Abbott. 

"Today definitely is a celebration," she said. "The city really did bounce back and was resilient, especially that 2014 year when it was a huge marathon."

Now, ten years later, Abbott runs a foundation that helps people who've suffered traumatic limb loss get expensive prosthetics. 

Big Z can do it all - Bruins legend Zdeno Chara finished his first Boston Marathon in 3:38 - an incredible mark for a first-timer.

American athletes in this year's Boston Marathon captured one title and finished strong in others.

Susannah Scaroni, from Washington, overcame a loose wheel to win her first Boston Marathon in the women's wheelchair race. Former Boston champion Daniel Romanchuk, from Maryland, finished second in the men's wheelchair division behind Switzerland's Marcel Hug. 

American Emma Bates finished fifth, and the BAA said her time of 2:22:10 was the second-fastest ever for an American woman in Boston, behind only Marblehead's Shalane Flanagan. 

Scott Fauble was the top-finishing American men's runner, coming in 7th.

Kenya's Hellen Obiri pulled away from the pack late and won not only her first Boston Marathon, but her first professional marathon.

Obiri was an injury replacement in the elite field of runners for the 127th Boston Marathon, but crossed the finish line before anyone else at an unofficial time of 2:21:38. 

She pulled away from a group of four other runners over the final couple of miles, beating out Ethiopia's Amane Beriso by 12 seconds.

Evans Chebet pulled away late and won his second straight Boston Marathon on Monday, beating out fellow Kenyan Benson Kipruto and Gabriel Geay of Tanzania over the final stretch of the men's race.

Chebet pulled ahead by a few seconds over the last mile to become the first back-to-back winner in Boston in 15 years. 

He finished the 127th Boston Marathon with an unofficial time of 2:05:54, beating his 2:06:51 finish in 2022.

Susannah Scaroni hit a little bump in the road early on Monday, but not even a loose wheel could derail her quest for her first Boston Marathon victory.

After taking an early lead, Scaroni had to pull over and fix a loose wheel ahead of the 15K mark. She not only kept her lead, but went on to double it as the race continued.

Up by just over a minute at the halfway point, Scaroni's lead was up to nearly two minutes by the 25k mark of the race. The 31-year-old from Washington led by nearly five minutes late in the race and won her first Boston Marathon by over a mile, finishing in 1:41:45 (unofficial time) on Monday.

The "Silver Bullet" is the Boston Marathon champ once again. Switzerland's Marcel Hug won his sixth men's wheelchair crown in Boston on Monday, taking the race with an unofficial finish of 1:17:06 to break his own course record.

Hug took a lead early in Monday's race and never looked back. He built a nearly two-minute lead by the 10k mark and was ahead by over three minutes by the 15k mark. 

His lead over Sho Watanabe and Jetze Plat was nearly six minutes by the 25k point, and continued to grow from there.

The 127th running of the Boston Marathon is officially underway.

The men's and women's wheelchair races got underway at 9 a.m., followed by professional men and women, and para athletics participants.

At 10 a.m., the first wave of runners took off on the 26.2 mile course.

David Ortiz will serve as the grand marshal of Monday's race.

He'll ceremonially guide runners along the course and will arrive at the finish line just before the champions break the tape.
