The race, in words
Sammy Lleras finished 822nd of 1,290 women in the Open division at Boston 2025, in 1:42:48.
A station race more than a running one: 50% of the field beaten on the stations, against 22% on the runs. The sandbag lunges cost the most time: 1:07 slower than the median. A harder second half: 1:41 more lost to the middle of the field after halfway than before it.
Boston gave the field time back: about 2:20 faster than the average race this season, by 670 athletes who raced both.
