The Boston Athletic Association honored Kathrine Switzer by officially retiring her No. 261 Boston Marathon bib number on Tuesday.
Switzer ran the 2017 Boston Marathon to commemorate the 50th anniversary of becoming the first woman to finish Boston with a bib number. Switzer, 70, finished the race in 4 hours, 44 minutes and 31 seconds.
The ceremony capped off a big weekend for Switzer, who ran Monday with 125 charity runners for her 261 Fearless foundation. In addition to holding court at panels and events throughout the weekend, Switzer also held the tape runners break at the Boston Athletic Association Invitational Mile on Saturday and threw out the first pitch at the Red Sox game on Sunday. And on race day, she fired the start gun for the women’s elite field.Follow Andrew Mahoney on Twitter @GlobeMahoney.
