Query over Personal Record

Former Member
Former Member
Hi,

On 8th March 2014 I ran 21.45km in a time of 1:54:43. On 23rd March I ran 21.28km in a time of 1:53:28.

The latter time appears (due to a km by km comparison, average time etc.) to be faster. Both qualify as a half-marathon, and yet Garmin does not recognise the latter time as faster (and hence a new personal record for the half-marathon).

Why would this be the case?

Thanks
  • According to the guidelines and your description of the situation, it should be. Here is a summary of the requirements.



    If it doesn't recognize your PR, you can manually make it a PR by clicking the little medal icon in the activity details view.

    Thanks Travis - when I do though, it takes the time for the 21.28km rather than the 21.1km as it should for a half.
  • This is the way it is supposed to work. Garmin Connect takes the total time and distance of the activity. Imagine that you do a 5mi run, and run hard for 3.5mi in the middle. Let's say that you ran a PR for a 5K during that 3.5mi hard section. Garmin doesn't find the 3.10686mi segment of your run and mark that up as a PR.

    Garmin takes the total distance of your activity and the total time of the activity. If you want to have Garmin Connect automatically detect your PR, you must start a new activity when you start running that PR segment, and you have to stop the watch and save the activity when you complete that segment. That is just the way it works. It works just like I'd expect when I'm running races or doing a time trial workout. It doesn't work well if you are setting PR in the middle of a normal workout.

    That might be how it's supposed to work, but I don't think that's really the way to do it. For example, my fastest 1 mile time should be, well, the fastest I've ever run a mile. I am *never* going to do a run of just one mile. That means Garmin will *never* show me a personal record.

    I've gone back and forth on several sites, and Strava does it right. It calculates the fastest you can each distance, regardless of the overall run. Why wouldn't I want to know that my fastest 5k time ever came in the middle of a 10k run?

    My watch and GCweb takes the best time for any of the PR distances from with in any of my new runs.
    One of my runs early this week was one running activity with Auto lap set to 1km. during that activity i correctly got new PB/records for fastest 1km , mile and 5km.
    Lastnights one 10.1km activity including walks and sprints gave me a new fastest 1km, 5km and 10km ( Auto lap and auto pause were both OFF).

    I agree. The Garmin system is inconsistent. I've run a range of distances and it routinely picks up PRs (e.g. my fastest 1km was derived during a 10km run, as was my PR for 5km). I was running an actual half-marathon event - so a little annoyed that Garmin doesn't recognise the distance as 21.1 km and, further, that it couldn't pick up a record. It's not like you can just knock out a half every day.
  • I'm not saying that is how it should work either. I'm simply stating what the current expected behavior is. That is how it works, and that is how Garmin documents it to work. If it doesn't work as documented, that could be considered a bug.

    It is entirely possible that Garmin will implement a system that splits activities up into segments at some time in the future. If you want it to work differently, you should post in the feature requests forum instead of at the end of a post where someone is trying to figure out how the existing system works.

    And as for Strava's superior method for detecting personal records and segments-- it is full of problems. I hold a record for a segment in front of my house. Apparently I covered .3mi in 6sec at 78bpm on a 29% grade for an average speed of 181mph. Under Strava's Estimated Best Efforts list it shows 1:29:50 for a Half-Marathon. I looked back through my history on Strava and I have 3 at 13.1mi, 1:25:54, 1:27:24, and 1:28:19. So their system isn't all that great.

    Not to mention that the folks over at Strava have recently implemented the All-Time PR feature that requires you manually enter your all-time personal records...

    All-time Personal Records (PRs) represent a runner's fastest time ever run for benchmark distances. PRs are manually entered, and can be linked to official race results and Strava activities. Whether the PR is from a track, road, or trail race, the PR is often verified by a known time over the race distance. We know that PRs matter down to the second, and we know that GPS data isn't quite as accurate as a time over a verified race course.

    How are All-time Personal Records different from Estimated Best Efforts?

    * All-time Personal Records = a runner's fastest time ever run over a distance in an official race, or over a verified, known distance
    * Estimated Best Efforts = training level insight into GPS based activities


    So, their system isn't really that different from what is going on with Garmin Connect.

    I like it the way it is now where it takes the best out of a longer run. The only problem i see is where you run a 1/2 or full and the watch misses 100m or so and does not reccognise a full distance , that would suck, like the OPs problem at the top..
  • The current system does not pick the fastest section of a longer run and treat it as a PR. i.e., if you run for 6.2mi and happen to run downhill for 1mi at a 4:55/mi pace, that mile is not considered a PR on Garmin Connect. The overall 6.2mi should be considered for a PR, but that is it.

    I regularly ride the same course of about 25 miles and have picked up 40k personal bests on a regular basis. I rode the same course tonight, beating my record, but it won't show up. :confused:
