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, held in Alberta, Canada, was recently revealed to be 674.7 meters (0.41 miles) longer than its intended distance due to construction work around the Wellington Bridge. The error caused runners to complete a slightly longer route than usual, which may have affected their chances of qualifying for the prestigious Boston Marathon and achieving personal best times. Organizers initially dismissed complaints from frustrated runners, but later admitted to the mistake in a statement on Wednesday, saying they "did not deliver the standard participants deserved". Race director Tom Keogh apologized for the error, which may have impacted the results of several athletes who participated in the event. The Edmonton Marathon is often used as a qualifier for the Boston Marathon, with qualifying times based on a participant's official chip time.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
