ESPN reporter Andy Katz was running the Boston Marathon for colleague Shelley Smith.
BC legend and former NFL great Doug Flutie was running for the Doug Flutie Jr. Foundation for Autism.
Rebekah Gregory was running to further prove her Boston strength.
Amy Keil was running six weeks out from her due date.
Katz, a senior writer who focuses on college basketball, wrote “#Shelley” and “Stu,” for former SportsCenter anchor Stuart Scott, on his bib.
He also wrote “Shelley” in black marker down his left arm. Smith announced in October she was diagnosed with breast cancer and has been off the air since, undergoing treatment.
She is set to return to work April 30.
Through The V Foundation, which was named for former NC State coach Jim Valvano and supports cancer research, Katz raised $10,728 with his 26.2 miles into Boston.
He finished Monday in 4 hours, 56 minutes and 31 seconds.
First tweet: I trained in snow, ice, wind, heat but never driving rain. I had injuries to calves and feet but never got cramps in quads.— Andy Katz (@TheAndyKatz) April 20, 2015

Crossing onto Boylston was awe inspiring.
Flutie crossed the finish line in just more than 5 hours at 5:00:42. He bested his 2014 time of 5:23:54, and, along with 15 charity runners called Dougie’s Team, rasied more than $200,000, according to the foundation’s website.
Gregory was 3 feet away from one of the bombs in 2013 and suffered injuries that led to the amputation of her left leg.
“I have to run that marathon — for myself, and for everyone watching to see that it’s only made me stronger,” she wrote in an essay for Vox published Monday.
Doctors warned against her running the entirety of the 26.2 miles, so she decided to start at Mile 23, though the pain proved to be too much to complete the final 3.2 miles. A police car drove her to Mile 25, and she completed the final mile with her trainer, Artis Thompson III.
Gregory collapsed on top of the finish line, overcome by emotion.
“But it was still an incredible feeling to cross that finish line, running,” she told espnW. “Better than I imagined. And I crossed the finish line — that’s what’s important.”
Keil, 7.5 months pregnant, wore a bright pink shirt, emblazoned across the front with the words: “Coming in 6 weeks!” She finished in 4:19:14, placing 9,315th out of 12,022 female finishers.
Other finishers of note include “Orange is the New Black” actress Uzo Aduba.

Sanca was on the UMass Lowell track and field team from 2007-10, running a personal best of 13:45.46 in the 5,000 meters as a senior before representing Cape Verde in the 2012 Summer Olympic Games in the same event. He was named UMass Lowell’s Male Student-Athlete of the Year in 2008 and 2009, and earned a bachelor’s degree in business administration. The O’Bryant High School alum later earned his masters degree in business administration from UMass Lowell before taking his post in the Office of Student Affairs.

Spencer McElwain, 25, Arundel, Maine
McElwain, an engineer at IDEXX Laboratories, finished in 2:34:03, good for 122nd overall.

He earned his bachelor’s degree in mechanical engineering from the University of Maine while competing for the track team from 2009-12. Monday was his second Boston Marathon. Last year, he finished in 2:37:58.
