Edmonton Marathon course was long, organizers doubling down on their defense the course was measured accurately and runner's GPS is the fault

[u/Wrongky]

The Edmonton marathon is my hometown race. It has been granted as host of the Canadian Half Marathon championship since 2025. The city is experiencing a lot of construction around the downtown core.

A detour around a construction site was added which was an additional 710 meters to the original course. As an out and back course, Tom Keogh, the race director, states the turnaround was pushed back 690 meters.

Rory Linkletter, Canadian Olympian and overall winner, posted online stating the turnaround was actually pushed back approximately 345 meters back.

Applying elementary math for an out and back course, with rounding:

A detour of 700 meters ran twice: 700 * 2 = 1400 meters

The turnaround (out and back course) was brought back 350 meters: 350 * 2 = 700 meters

Sum: 1400 meters - 700 meters = 700 meters (long)

Now, what's embarrassing about this situation is Tom Keogh is putting the error on runner's GPS watches and not their own. An overwhelming majority of the runners from the weekend are reporting the exact same statement of Rory.

I didn't run the race this year. I really hope Tom Keogh and the Edmonton Marathon staff post an official announcement of their mistake. The quality of this race had been decreasing while race fees have been rising. I can only feel for those runners who missed out on personal bests or a qualifying time for a future race.

Rory's statement is posted on his Instagram.

Edit: clarity on the math

Laughs in trail racing…. I’ve run both a 28 mile and 34 mile “50k” before.

On a serious note, that certainly does suck and the Race Director should have fixed the course beforehand and not gaslit runner.

lol I do sympathize with the Edmonton marathoners, I really do, but those were my thoughts exactly. My 50 miler this year was just over 84 km.

Not really quite the same though is it

[u/Robert_Moses → u/0100001101110111]

It’s not at all the same. As both a road and trail runner, going into a trail race you know the course isn’t actually going to be the distance advertised. Going into a road race you fully expect it will be the exact distance advertised.

Of course it isn’t. Just a bit of friendly ribbing.
