Open Water Swim metrics screwed up by Triathlon run to transition

I have a suggestion for improving how Garmin Connect handles Triathlon activities. Many triathlons include a significant run from the swim exit to the transition area, and have the timing mat positioned at the transition area entrance. So our "swim" time ends up including a significant amount of running. If we press the Lap button on our devices at the same time we cross the timing mat to keep the results aligned then that screws up the Open Water Swimming metrics in Garmin Connect. So I would like to recommend that Garmin add a feature to mark part of an Open Water Swim inside a Multisport activity as being actually a Run after the activity is over.

The other alternative today is to press the Lap button as soon as I exit the water, but then my times recorded in Garmin Connect for the Swim and T1 won't match the official race results.

  • What about pressing the stop (pause) button when you complete the swim, then pressing it again when you are ready to cycle? You would need to press the lap button just before pausing, or just after restarting the activity.

  • Sure you can do that, but then your activity time won't match the official results and you won't have a GPS track for the run to transition. So it doesn't solve the problem.

    You could always create a custom multisport activity with a run segment added between the swim and bike to accommodate this.

  • BTW, do you have the Transition option in the Triathlon settings turned on or off? I do not have a watch with the Thriathlon mode, so cannot test it, but since you have one, I believe it should take care exactly of this issue. Not sure what device you use, but it is described for example in the Forerunner User Manual:

    https://www8.garmin.com/manuals/webhelp/forerunner945/EN-US/GUID-1E324657-F8AE-4C82-AD3D-481746CBC872.html

  • My Forerunner 935 does have a Triathlon activity and I used it on this race however that doesn't solve the problem. When you start the activity it will be in Open Water Swim mode. Then pressing the Lap (Back) button switches immediately to Transition mode. But if you press it as soon as you exit the water in order to keep the Open Water Swim data valid then the time for that first part won't match the official race splits. And if you wait to press it until you run to the timing mat at the transition area then you will have recorded a "swim" on land.

  • But if you press it as soon as you exit the water in order to keep the Open Water Swim data valid then the time for that first part won't match the official race splits.

    Frankly told, I have no idea how the official race splits are calculated, and as I do not have the Triathlone mode on my watch, I do not know what impact the Transition mode has either. From the user manual I understood that, when used, the first lap is the swim, the second lap is the transition, the thrid lap the cycling, the fourth lap another transition, and the last lap the run. Isn't it so? And when yes, what's wrong with it? What are the official rules? And perhaps you could post links to two different  triathlon activities of yours - one with the Transition mode on, and the other without, so that we see what differnce it makes.

  • Official race splits are calculated when your timing chip crosses one of the mats.

    There isn't really a Transition "mode" as such, it's just another type of activity like any other. Each time you press the Lap (Back) button it automatically switches to the next activity type in the Triathlon sequence: Open Water Swimming → Swim to Bike Transition → Cycling → Bike to Run Transition → Running.

    Here's an activity link if you're curious: https://connect.garmin.com/modern/activity/4609219823/1

  • There isn't really a Transition "mode" as such

    Did you actually read the link to the User Manual of Forerunner 945, that I posted above? Is it different on your watch? In FR945, there indeed seem to be the transition mode - they explicitely tell it can be turned on or off:

    • Select <> at the beginning and end of each transition.
    • The transition feature can be turned on or off for the triathlon activity settings

  • Official race splits are calculated when your timing chip crosses one of the mats.

    Yes, but I have no idea where the mats are. At each side of the transition, or on one side only? If so, then where - at the water exit, or at the cycle start? 

    How exactly would you like that GC shows the results? What is exactly wrong with the following values? I could possibly adjust it as needed with the help of GCOverrides, if it is something that other triathlets could use too.

  • OK, I've reread you initial post, where you tell the mat is at the entry of the transition, but I am still not sure whether I understand how you need the data to show up, to match the official results. I also do not know whether there is a timing mat at the transition entry, and another one at each side of each discipline, or whether the mat already starts the next discipline timing.

    There is the swim time, the time between water exit and the transition mat, and then the next discipline. So I see four possibilities (using the times from your activity as example):

    1. Swim time (17:05) + run to the transition mat (2:28.8) + cycle (36.03)... 
    2. Swim time incl. the run (17:05+2.28.8) + cycle (36.03)
    3. Swim time (17:05) + cycle (36:03) (excluding the run to the transition mat)
    4. Swim time (17:05) + cycle (36:03+2.28.8) (including the run to the transition mat)

    From your text, it is apparent that none of the above possibilities is correct, so I am curious how it should be in fact. As I wrote, if you explain it comprehensively, I can very likely write an override script to modify the interface accordingly, but need to understand what you actually want.
