Maria Zambrano Shatters Records at Chicago Marathon
Calgary’s Maria Zambrano has once again made headlines in the running community by setting a new Canadian masters record in the women’s 55-59 age group at the 2025 Chicago Marathon. Just two days after celebrating her 55th birthday, Zambrano clocked an impressive 2:49:47, securing her victory in the category by a substantial five minutes.
This remarkable achievement placed Zambrano as the 112th woman overall to cross the finish line, where she shattered the previous national record of 2:58:46, held by Allison Blackmore since the 2023 Tokyo Marathon, by a substantial margin of nine minutes.
Zambrano, a distance runner from Alberta, already holds national records in both the women’s 50-54 and now the 55-59 divisions. Her personal best of 2:44:37, achieved during the 2024 Houston Marathon, remains the national record for the 50-54 age group.
In a previous interview with Canadian Running, Zambrano discussed her motivation for continuing competitive running into her 50s. “I think there’s no secret,” she explained. “It’s just doing the training, being consistent, and wanting to do it.” Such determination not only fuels her ambitions but also serves as a powerful source of inspiration for other women in her age group.

In addition to Zambrano’s triumph, Canadian runners enjoyed further success at the Chicago Marathon. Ottawa’s Joel Koffman clinched victory in the men’s 75-79 age category, finishing with a time of 4:10:36.
