Data suggests that marathoners run their fastest races when the temperature is in the 40s — but the study did not take wind into consideration. Others did not share Kawauchi’s opinion on the conditions.
“The cold, the wet and the rain — that’s the three worst things you can have, and you have that in one race,” Abdi Abdirahman, a four-time United States Olympian who finished 15th on Monday, said on Sunday night. “A lot of guys have been talking about it, trying to be the tough guy and say, ‘Oh, I’m not worried about it, I will just have to deal with it.’ But you know, we will find out how many people are still intact after 30K.”
The temperatures and winds led to slower race times. Runners were mostly reluctant to move in front of the pack early on. Geoffrey Kirui of Kenya finished second in 2:18:23, and Shadrack Biwott of the United States was third in 2:18:35.
Tim Don, the world-record holder in the Ironman triathlon, who broke his neck six months ago, finished in 2:49:42.
The rain was so bad that the traditional Patriots’ Day Red Sox game was postponed for the first time since 1984.
And there were certainly fewer fans than usual cheering along the course. Some who braved the weather taped plastic bags to their sneakers and wore trash bags in lieu of waterproof jackets.
At the starting line, runners crossed their arms over their chests, rubbing their forearms and jumping up and down in an attempt to stay warm. The athletes were all given two bib numbers so they could put one over each layer of clothing.
