I ran a 5k Saturday. My Garmin said the course was only 3.06.
Is the race off or is my Garmin off. This just really messes up my log.

You should immediately file a protest with the usatf and the RD. Don't let this injustice go unchallenged. No justice. No peace.
sue the carp out of them. they advertised a "5k" and only provided something like 4.94k. unacceptable.
so would log the pace from the race results which is better than the garmin. or should i log the garmin.
I want to log the race results. why do i have so much faith in my Garmin. It could be off.
Am I correct in understanding that a dead straight line course will show up long on GPS, and a winding course with sharp corners will end up short?
This is my theory based on limited frequency and precision of waypoints plotted.
Your Garmin is correct and I give your trolling a 3/10 since you got a few responses.
Why does everyone think their Garmins are that accurate?
always count on a 2-3 % error.
Thats why I prefer Polar heart rate monitors.
I'll bite, but only because you used "log" three times in one post.
Log whatever you normally log so that your log is consistent. Other than that, it just doesn't matter.
In general, a Garmin will normally run a bit long, so your race was probably short. If you load that to Garmin Connect and claim it as a 5k, we will ALL know that you are a liar and a fraud.
Of the certified courses that I have run, the Garmin has ranged from 3.10 to 3.16. It will vary more depending on the number of turns and changes in elevation, but it has never been less than 3.1.
Remember, measuring by any GPS is not the same as running with a 3+ mile spool of steel measuring tape. The GPS pings your location from a spot way up in space every few seconds and estimates how far you have gone. It might sound real sciency, but it is not 100% accurate.
Never wear a Garmin on a marked course. It doesn't matter if it's a race or a workout.

I award a 6/10 for the effort, because we all actually know people like this.

False.
Your garmin and other GPS devices work like this:
Every ~3sec your GPS device will take a point location of where you are. The GPS device then plays connect the dots with each point. It calculates the time and distance you covered to give you pace.
Your GPS device will typically be short. When the GPS links your points together, it does so in a straight line, not the curved line you may have taken to get between the two points. In very wooded areas, tight and curvy routes, and cloudy days, this error is increased because of the 3 second delay and reception issues.
As accurate as we like to think or devices are, the government limits the ability of pedestrian use. We can only get accurate points within 5-10ft of where we actually are. The army/military/government issued GPS units can be accurate within a few inches. They do this on purpose probably for safety and security reasons.
Finally, to get back to your claim of a short course, it may actually be the right distance. It is completely reasonable for the Garmin to short you 0.05miles over the course of 5k.
I would calculate the equivalent time for the whole 3.1. I know it's an extra step, but it's easier to keep an accurate log when your distances are standard.
Thanks for all the reply's. If I would of run the 5k and not had a garmin, My log would show the results of the race. Garmins are so controlling. I have a love/hate relationship with it. I am a data whore, but my most enjoyable runs are when i forget the garmin.
6/10 wooohooo!

It's okay. You ran far enough that you can put the 5K sticker on your minivan.
hahahah, i'm still looking for a 100m sticker...

This guy is right. Curves, trees, buildings mess it up.
There was a very poorly written article in the NY Times about how Garmins are wrong because a bunch of NYers told the "author" that, while running in the city (and Central Park) their Garmins were often/usually wrong.
NYC?Central Park- has BUILDINGS and trees and winding paths.
I live in a small town and find mine to be amazingly accurate.
We've had guys, each with their own Garmin, Nike, Timex, come out the same to the 100th if a mile on certified 10k courses running together in training.
That said- anyone can mess up the start or finish of a certified 5K.
I was ran a 5K out and back and they made us run 150 meters too far to the "wrong" landmark to turn around.
Did you check the map on the Garmin site.
Garmins can only be accurate based on the number of satellite trackpoints.

I didn't see on but Zazzle has tons of Euros including one which says "0.0 But seriously, good for you." another says "got toenails?"- I thought that was clever.

If the course is certified and was properly set up according to the certification map then most likely the course is right and your Garmin is wrong. If the course isn't certified then most likely both the course and your Garmin are off.
