Race Details
The 2026 Edmonton Marathon was found to be 674.7 metres longer than the official distance, thanks to a construction detour around Wellington Bridge. Organisers said the unexpected detour added extra mileage to the course.
Many runners were frustrated after their GPS watches recorded over 26.22 miles. Since the Edmonton Marathon often serves as a qualifier for the Boston Marathon, the extra distance could jeopardise athletes’ eligibility for the larger race and impact their personal bests.
Race director Tom Keogh noted: "We do not take this lightly. The athletes’ performances were not properly reflected by the longer route." He added that organisers had failed to meet the high standards athletes deserved.
Organisers are now working with Athletics Canada and other partners to determine how this year's results should be recognised. Official chip times—not watch data—are used for Boston Marathon qualification, but organisers plan to compensate for the mistake where possible.
The incident underscores the importance of accurate course measurement in elite racing and highlights the need for transparent communication between race teams and athletes about any deviations that could affect qualifying criteria.
