Pregnant runner at Boston

Calli Hauger-Thackery ran the 2026 Boston Marathon while 22 weeks pregnant and finished in 2:43:58. (runnersworld.com) The British Olympian, 33, crossed the line on Monday, April 20, in the professional women’s field at the 130th Boston Marathon. Boston.com reported she raced with bib No. 114 after returning to Boston a year after her sixth-place finish. (boston.com) A year earlier, Hauger-Thackery ran 2:22:38 in Boston, and World Athletics lists her marathon personal best as 2:21:24 from September 29, 2024. Her 2026 season also included a 2:24:17 win at the Houston Marathon on January 11. (runnersworld.com) (worldathletics.org 1) (worldathletics.org 2) Her Boston run landed well behind the front of the race, where Sharon Lokedi repeated as women’s champion in 2026. Hauger-Thackery said before the race that this was not a podium attempt and that her goal was to get herself and her baby to the finish. (olympics.com) (boston.com) Pregnancy does not automatically rule out running, but the guidance is individualized. The American College of Obstetricians and Gynecologists says women who already did vigorous aerobic exercise before pregnancy can usually continue during pregnancy if they do not have medical or obstetric complications. (acog.org) Tommy’s, the U.K. pregnancy charity, gives similar advice: runners who were already running regularly before pregnancy can keep going as long as it feels comfortable, but people who did not run before pregnancy should not start with running while pregnant. (tommys.org) That makes Hauger-Thackery’s Boston effort unusual less because she ran while pregnant than because she covered 26.2 miles at elite-race pace. She told Runner’s World it will likely be her last “proper race” for now and said recovery after Boston would depend on how her body responds. (runnersworld.com) Her result also came in the middle of one of the strongest stretches of her career. The Boston Athletic Association previewed her as one of the experienced women in the 2026 field after a 2025 season that included Boston and the World Championships marathon. (baa.org) At Boston, the finish time mattered less than the fact of finishing. Hauger-Thackery left with another medal, then said the next phase would be recovery rather than racing.
