Edmonton Marathon apologizes, says detour error lengthened 2026 race distances
The Edmonton Marathon has admitted that a detour error resulted in race courses being longer than the certified distance. Organizers apologized for the mistake after initially insisting the measurements were accurate despite complaints from runners.
Why it matters
Accurate course measurement is critical for the integrity of competitive running events and the validity of athlete records.
The acknowledgment confirmed what many runners said they had suspected.
In a statement issued Tuesday afternoon, Edmonton Marathon race director Tom Keogh said the distance of the half-marathon and marathon courses measured 674.7 metres longer than previously thought.
“The Edmonton Marathon’s previous statement detailing confidence in the course certification process was issued with the best information it had at the time,” Keogh said, adding that event officials conducted a thorough review of the course.
“That review has identified an error in how this year's detour-related course adjustments were calculated and for that we sincerely apologize.
“The additional distance added for the Wellington Bridge detour was partially offset with adjustments made to the course's west end turnaround point. Upon review it was determined that the turnaround point did not fully offset the addition of the detour.”
