Quick Summary

The Edmonton Marathon organizers in Alberta, Canada have admitted that the 2026 course was 674.7 meters (0.41 miles) too long due to construction work around Wellington Bridge. Runners noticed their GPS watches recorded over 26.22 miles, and while the error won't affect qualifying times for the Boston Marathon directly, it may impact personal best times. Organizers initially dismissed complaints but later apologized, stating that they "did not deliver the standard participants deserved". The mistake has left participants potentially missing out on personal bests.

Story summary

The Edmonton Marathon in Alberta, Canada, which is often used as a qualifier for the prestigious Boston Marathon, had a course that was 674.7 meters (0.41 miles) too long during its 2026 edition. Organisers initially dismissed complaints from runners who noticed their GPS watches showing distances over 26.22 miles, but later admitted to the error in a statement on Wednesday. The mistake was due to construction work around Wellington Bridge, which forced a slight detour from the usual course route. As a result, some participants may have missed qualifying for the Boston Marathon or achieving personal best times, as their official chip times were not accurate reflections of their performances. Race director Tom Keogh apologised for the error, saying that organisers did not deliver the standard participants deserved.
