Overview
- Runners reported that GPS watches and in-race splits did not match expected progress during the Edmonton event held on Sunday, Aug. 16, prompting complaints from elites and recreational participants.
- Organizers and Athletics Canada initially stood by a physical course measurement confirmed by a World Athletics/AMS Grade A measurer before the race.
- After reviewing participants’ reports, the Edmonton Marathon issued a public apology and said it found a detour-related calculation error that increased the course distance by 674.7 metres.
- Race results have not been formally nullified and organizers say they are working with Athletics Canada and other partners to decide how to handle qualifiers, records, and affected placings.
- The episode highlights how a local route change can add real distance beyond GPS drift and that many runners may have missed Boston or championship qualifying times or record opportunities because their courses were longer than advertised.
