In brief
In a surprising turn of events, the 2026 Edmonton Marathon finished 674 metres longer than the official distance, affecting the performance metrics required for Boston‑Marathon qualification. Runners reported distances over 26.22 miles on GPS watches, leading to disappointment and a subsequent apology from race director Tom Keogh. The organisers attribute the mistake to a detour around Wellington Bridge construction and are now collaborating with Athletics Canada to determine how to rectify the results for athletes affected.
The Edmonton Marathon organisers have admitted that the 2026 edition ran 674.7 metres too long, a discrepancy that could cost participants a chance to qualify for the prestigious Boston Marathon.
Participants and runners who measured their finish distance reported more than 26.22 miles on modern GPS watches, raising frustration after the event.
Race director Tom Keogh said the team “do not take this lightly” and acknowledged that the miscalculation “did not deliver the standard participants deserved”.
The error was traced to construction around Wellington Bridge that forced a slight detour from the typical route, inadvertently adding the extra metres.
Because Boston Marathon qualification relies on official chip times rather than personal GPS recordings, most athletes may miss the time cut just short of the required distance.
Organisers say they are engaging with Athletics Canada and other partners to determine how to award this year’s results and whether a retroactive adjustment can be made.
The incident underscores the importance of precision in high‑profile sporting events, where even small measurement errors ripple across national qualification pathways.
