Linden passes Chesir and Daska in 22nd mile.
Shalane Flanagan took a detour about halfway through the Boston Marathon — a reported 14-second trip to a port-a-potty.
Flanagan, the 2017 New York City Marathon champion and a four-time U.S. Olympian, was seen talking to countrywoman Desi Linden before veering off to the right to a row of portable bathrooms.
Flanagan’s break was timed at 13.86 seconds, according to Jonathan Gault of LetsRun.com’s Twitter account.
Linden held back to help Flanagan return to the lead pack.
Flanagan, 36, is running Boston for the fourth and likely final time as an elite racer. She grew up in nearby Marblehead, Mass.
The weather is likely the coldest in 30 years, according to organizers of the world’s oldest annual marathon — sub-40 degrees at the start with constant rain and winds of about 20 mph.
