Yes it is possible as a simple search would reveal - edit swim distance Garmin
Hey Sandminer. Go to your smart phone, open Garmin Connect. Select the specific swim session and when the high level summary screen opens tap on the 3 vertical dots in the top right of the screen. Select…
Exactly this! I have this problem even 3 years after your comment. If you basically pause to look at your watch mid-length, it thinks you have finished a length and started a fresh one! So I have pairs of 30 sec lengths (ie one 25m length with a pause midway...) which I can never in a million years hope to replicate - you can see the spikes on the graphs - but I cannot figure out how to merge those 2 "lengths" into one proper 25m length... I find it ridiculous, as clever as this watch is (Forerunner 245) that it cannot tell whether you have stopped, and restarted 180 degrees in the opposite direction, or whether you have merely paused mid-lap and carried on in the same direction. Crazy.
Solution: login to Garmin Connect ON LINE (not on phone app). https://connect.garmin.com/ Select activity you want to edit. Click the pencil in the far top right corner which allows you to make edits. Then you'll see it still does not allow you edit "distance." However it does let you edit "Number of Lengths." I just did this on today (March 10, 2022) and then it recalculated the distance. I had to do this because my garmin watch did not pick up my laps when I was just using the kick board and not moving arms. Just calculate the number of lengths you need to add. etc.
GOOD LUCK!
Thanks for that Yeah that doesn't really solve the problem of "rogue" individual lengths which have been recorded as extremely short splits... You can actually edit number of lengths (and therefore distance) through the app - I have done that many times, but it cannot remove individual lengths which have been recorded at half distance because I glanced at my watch halfway through a length... I guess the problem is that the watch isn't as smart as it could be. I'm sure there must be third party software which can dig into the metadata and achieve this - but to be honest I CBA. It should just work - the watch should be smart enough to register that during a "pool swim" profile whether or not I have merely looked at my watch, or stopped, turned around and set off again in a 180 degrees opposite direction - I'm disappointed it can't handle that.
In the web version of Garmin Connect, I do not see a pencil in the top right corner which allows for edits.
You have to enter the activity page with details, first. You are staying just on the list of all activities, where you can indeed edit just the title, and the subtype of the activity.
'm sure there must be third party software which can dig into the metadata and achieve this
Yes, there are some. Look for example at www.swimmingwatchtools.com/upload
Thank you very much ! that way indeed then number of lengths can be edited.
Though still as not all lengths were under the same stroke, Garmin should provide a different UX for this.
Maybe the best way to use a Garmin watch when swimming in a pool is to create a custom workout. So far I'm not thrilled with UX for swimming in the app and web, stroke detection isn't great either.
