Boston Marathon 2018 Live: A Cold, Rainy Day Greets Runners As The Race Begins

The field of nearly 30,000 runners in Monday’s Boston Marathon will be battling rain, wind and cold.

Race officials announced that the temperature was 38 degrees at the 8:40 a.m. Eastern time start in Hopkinton, Mass., making this the coldest start in 30 years. The National Weather Service predicts that rain will be heavy by early afternoon, with winds of 25-40 mph coming out of the east (and right into runners’ faces). The high temperature is predicted to be 49; at 7 a.m., it was 37. The forecast forced postponement that other Patriots Day tradition, the Red Sox game against the Orioles at Fenway Park.

This is the 122nd running of the marathon and it comes a day after the fifth anniversary of the 2013 bombings at the Boylston Street finish line. The race, on Patriots Day in Massachusetts, now marks milestones of remembrance and survival, the taking of one step followed by another over the years.

The man who captured the explosions looks back

Five years later, Steve Silva recalled being at the finish line and shooting video of the explosions that was shared globally. “It wasn’t a bone-rattling explosion like you might imagine — more of a muffled thud with a large plume of smoke that ran straight up the mid-level buildings on that block of Boylston,” Silva writes.

“My first thought was that it might have been a fireworks celebration that perhaps went awry for the Hoyts’s finish. But 13 seconds later, the second explosion went off just over a block away. ‘We’ve had an attack,’ I said into the camera’s microphone.

“In a split-second, I went from sports video producer to accidental war correspondent.”

Top runners include a strong American women’s field

The women’s field includes five of the all-time fastest marathoners in the United States.: Shalane Flanagan, the 2017 New York City Marathon champion; Desiree Linden, a two-time Olympian; 45-year-old Deena Kastor, holder of the American record in the marathon; and Molly Huddle, the American record holder in the 10,000-meter and half-marathon. Last year’s champion, Edna Kiplagat of Kenya, also returns.

Jordan Hasay, who placed third in Boston and Chicago last year and was one of the top American women in the field, withdrew late Sunday because of a stress reaction in her heel. She had been battling plantar fasciitis over the past few weeks.

The men’s field features Americans Galen Rupp, winner of the 2017 Chicago Marathon; Dathan Ritzenhein, a three-time Olympian; Abdi Abdirahman, a four-time Olympian; and Shadrack Biwott, who was fourth in 2017 in the Boston race. Nine Kenyan and Ethiopian male runners with personal bests of under 2:07 will compete, including Geoffrey Kirui, who won the 2017 Boston and IAAF World Championships marathons.

If you’re going …

Security for the 26.2-mile race has been tightened since 2013 and spectators, who are expected to number more than 50,000, are reminded of what is and is not allowed, particularly close to the finish line.

At least five transgender runners will compete

Marathon organizers are not concerned about gender boundaries, saying that transgender runners can compete using the gender they qualified with.

At least five openly transgender women have signed up to run the race, and a BAA official told Runner’s World that race officials and volunteers would compare gender identity on the government-issued ID required to pick up a bib number with what’s on runners’ entries.

If there’s no match, a BAA spokesperson told Runner’s World that it would be addressed “in a manner intended to be fair to all concerned, with a strong emphasis on inclusion.”

“We take people at their word. We register people as they specify themselves to be,” Tom Grilk, who heads up the Boston Athletic Association, told the Associated Press. “Members of the LGBT community have had a lot to deal with over the years, and we’d rather not add to that burden.”

Amelia Gapin, a transgender woman from Jersey City, heads up a social media group for trans runners and told the AP: “It’s kind of murky how people handle it. We are such a small percentage of the population that we generally just fly under the radar.”
