Overview
- Runners who ran the event on Aug. 16 reported GPS watches, chip splits and odd kilometre markers that suggested the half and full marathon were longer than advertised, triggering complaints.
- Organizers initially defended the certified course but after a remeasurement on Tuesday race director Tom Keogh said a detour-offset calculation error added 674.7 metres to both the marathon and half-marathon.
- The mistake stemmed from a Wellington Bridge detour that was only partially offset by a revised turnaround point, meaning the detour distance was not fully subtracted from the route.
- The extra distance altered elite and recreational finishing times, possibly costing some runners Boston Marathon or other qualifying standards and affecting records and selection opportunities.
- Officials say they are working with Athletics Canada and partners to decide how results and qualifiers will be handled and to review certification procedures to prevent future measurement errors.
