Suggestions to register a swimrun activity: indoor pool swim circuit + run

I'm going to make a very small aquathlon next saturday, but i'm not exacly sure how to register this with the FR935.

It would be a multisport activity: pool swim activity + run activity. But it isn't a standard pool swim, as it is a circuit on an indoor olympic pool, so the watch wont be able to count pool lengths.

Any suggestions for settings for the pool swim activity?

Open water swim activity doesn't seem to be an option because it needs GPS and the pool is indoor.

One option would be to set the pool activity with a single length defining for that length the all activity distance (in this case 300m). Is this possible?

If someone has already done something similar, please say.

Thanks.

  • I believe the maximum pool size is 150 meters. I'd just use open water swimming for the swim leg, which obviously won't register any distance, but then you can edit the distance in Garmin Connect after download.

  • Yes maybe it’s the best option. 

    I was thinking in using pool swim and then edit the distance, but maybe open water is better. 

    I’ll use the SwimRun activity with open water first and run second. 

  • Perhaps use the pool swim setting but with drill mode. That way you'll record the time then can manually add the distance

  • I think drill mode is not the best idea. Here's why:

    1. After finishing a drill you enter the distance in multiples of pool size. What pool size would you use for a 300m loop?

    2. AFAIK in drill mode you loose stroke metrics.

    3. I'm not even sure how entering a drill distance would work in a multisport mode. I'd rather avoid fiddling with drill distance when it's time to jump out of water and start running.

  • I tried it and drill mode is not acessible in multisport/swimrun activity.

    I think pool swim or open water will do. On both i'll have to edit the distance.

    With pool swim i would set the pool size to 50m and then see what it measures.

    I'm not sure yet which i'll use tomorrow.

    Mainly what i need is a timer, if with stroke metrics, better then.

  • If you set the pool size to 50 m, then 50 m will be added every time the watch thinks you completed a lap, for example when you stop for a second or change direction. And if you swim smoothly, without any breaks, then the watch will count only a single 50 m length. I think it would be pretty unpredictable in your case (swimming in loops). And while it's possible to edit total distance afterwards, it's not possible to correct length numbers. This is why I recommend open water swimming.

  • The circuit (last two pages): http://jamor.ipdj.pt/upload/2019%20JSS/aquatlo_2019_per.pdf

    This is a celebration event, the overall distance is not competitive. Well... I'm a begginer swimmer, and 300m free aren't that easy for me. Running 2kms is nothing.
    Another motivation for me is to incentivate my ten years kid to this kind of competition.

    The length count will be unpredictable, as the swim might be inconstant (turns, other swimmers). Because of this there isn't a optimal length distance, 50m, 100m or 150m. I could set 100m ou 150m and then try to force a length count by hiting a float or the pool wall, but that isn't easy to do or control during the race.

    I'll go for open water.

  • I wonder if the lack of GPS signal may not corrupt the activity file?

    In the last two months I got two corrupt pool swim files due to bad HR data (I used HRM-Swim as always).

  • Should be ok. I'd even advise turning off GPS for the open water swimming profile for the event, just to make sure that intermittent GPS signal does not produce weird GPS track.

    To verify if everything works as expected just make a test dry run before the race.
