Edmonton Marathon Route Measured 674 Metres Too Long

Organizers of the 2026 Edmonton Marathon have acknowledged that the race route was 674.4 metres longer than the regulation marathon distance, following complaints from runners about their recorded distances and finishing times. The Guardian reported that the event team confirmed the discrepancy after examining the course used for Sunday’s race.

Watch the highlights:

A standard marathon covers 42.195 kilometres, or 26.2 miles. Adding 674.4 metres pushed the Edmonton course to roughly 42.87 kilometres, a difference large enough to affect every finisher’s official time. Race director Tom Keogh said in a statement issued Tuesday that the times posted by the athletes did not accurately reflect their performances.

According to the organizers’ review, the extra distance resulted from a detour introduced to avoid construction near Wellington Bridge. The event had initially maintained that the route was certified and the correct length when runners first raised concerns. Organizers subsequently reversed that position after their examination identified the added section.

The mistake has particular competitive significance because athletes use certified marathon results to measure personal bests and pursue qualifying standards. The Guardian reported that Edmonton attracts runners seeking Boston Marathon qualification, where relatively small differences in finishing time can affect whether an applicant secures a place. The report did not establish how many runners, if any, lost a Boston entry because of the error.

Canadian Olympian Natasha Wodak was among the runners who questioned the course. She told CBC that her pace appeared unexpectedly slow over the final few hundred metres and that her finishing time prompted immediate surprise. Wodak also stressed the importance of accurate measurement for participants who commit time and money to chasing performance goals.

Keogh said the event does not take the mistake lightly, especially because the race hosted leading Canadian athletes. Organizers said they will review the certification process in an effort to prevent a repeat. The confirmed finding leaves the 2026 results standing as performances recorded on an overlong course, while the broader consequences for individual qualification attempts remain uncertain.
