I haven’t seen anything published as to how TP does it and I am not a TP user myself so I am not sure. Maybe HRSS if your resting HR and max HR are correct?
I’ve found this article that says that “hrTSS will only be used if there is not enough data to calculate TSS, rTSS, or sTSS” so you are probably right.
The two metrics differ because the default for cycling here is Time in HR Zones and not HRSS.
What’s your logic for making StandUpPaddling fitness 0.0 fatigue 0.0?
I have only seen people doing it and didn’t look like much cardio … but open to suggestions from actual standup paddling people

I am using Ice Skating as my activity for speed skating. Would you assume that a factor > 0% for Fitness apply to this type of activity? What % would you then to apply? Attached is a view of my latest skate.
Thanks,
That looks like cardio from the HR traces so probably best to go with 100% for fitness and fatigue.
Hi David! I’m quite new on Intervals.icu but I like it so much and I believe it can help also stand up paddlers. I’m a SUP coach and I start to use Intervals.icu to work with my athletes. I have a couple questions:
- Is it any chance to get the “distance per stroke” data that Garmin already provides? For now, we don’t have any way to measure the power per stroke, so “distance per stroke” is the only way to get an idea about how strong we’re paddling in each stroke, intervals and session. Of course wind, currents and ocean conditions affects a lot on this value, so it’s only helpful when we paddle on a “perfect” conditions.
- I can see the presets for HR Zones, changes on % according if it’s used for cycling or running, witch one do you think it would be better to use it on stand up paddle.
- In our sport we can use different equipment (boards and paddles) according the discipline (sprints, long distance, open ocean, flat water). Garmin has already the feature to predeterminate more than one equipment per sport and change if it’s needed. Could you also take this data? I saw in Intervals I can add my equipment but I only can default one, so would be perfect I could chose a board and a paddle.
Thank you!
Thanks! I added a custom activity field to calculate distance per stroke:
You can add that to your athletes. Select one of the athlete’e SUPs and click “Custom” under the activity timeline chart and then search for the field:
You will need to re-analyse existing activities to see the new field value.
Unfortunately you can’t see this for intervals yet, only the whole activity. I will be working on custom fields for intervals soon.
I don’t know what set of HR zones would be good for SUP. I only do cycling myself.
I have added a top level gear type “Board” and a component “Paddle”. Currently to select different sets of equipment you need to create multiple top level gear items and configure them differently.

Totally amateur SUPer here, but the me who undertook a 220k event over 5 days in September, where I spent up to 8h in Z1-2, feels very much that SUP is cardio 
. I agree that probably most people practice SUP for a bit of outdoor chill, but these people mostly won’t be recording it on their Garmin and/or Strava. Your choice is not too much of an issue having the ability to make it 100% contributing for myself, but I do think the default, for your audience, could be 100%.

Thank you for the Distance per Stroke feature! That metric is also very used by rowers for on the water work, so I have added it to my OTW rows. I would suggest editing the description to say it is for SUP and for rowing (and possibly other paddle sports, to double-check).
Good luck on th 11SUPCity Tour, I did it in 2018 the non stop and 2023 seems I’ll back, not sure yet on the five days or non stop again.

Hi David!
thank you for adding the metric, when we can get it fo intervals would be perfect!
About the equipment, I’m affraid I didn’t explain mysel properly. The paddles aren’t a component, they’re part of the equipment. The point is it would be awesome to define my default equipment for SUP:
- board: Sunova 14’ x 21’5
- paddle: Quickblade T2
so when I check my training I can see the equipment use it, but if for that training I used another board or paddle be able to change it and add the kms to this equipment.
I hope I’m more clear now. Thank you!
That would mean nested equipment or more than one “gear” per activity - as of now this is neither supported nor on a short list of todos (at least that was the status the last time I asked)
so in your case having “board” as component would be the way to go → that way you create different “gear” elements for all combinations and have “board” and “paddle” both as components to that “gear”
that way the individual components (board, paddle) get time tracked base on which “gear” (or rather setup) you chose for that activity.
You can get distance per stroke for intervals. Click the search button:
Re the equipment having more than one gear per activity is probably what you need. I might do that at some point but it does complicate quite a lot of stuff.
I have made SUP count for cardio by default. That sounds like a bit of work!

great David, thank you so much!
No worries about the gear, it’s not super important, thank you anyways!
thank you for your reply! well, the point would be to have the chance to choose the gear used in each activity, board and paddle. I hope one day we can get it!
Hi David!
do you know why the same training looks so different in two different athletes? is that normal?
I’d like to hear (discuss) a little more about the science behind this: take for example hot yoga: it doesn’t increase cardiovascular fitness? I agree with strength training but I’m not really sure I agree with the sentence that heart rate only goes up because of thoral pressure.
Heart rate goes up because your muscles need to work harder.
I get why weight lifting is not aerobic, but why rock climbing? Isn’t that mainly just lifting your own weight slowly up a cliff face using either your leg muscles (preferably) or your arm muscles, (or any muscles you can, come to think of it)?
p.s. Beginning to really get into what you have done!
One of the biggest challenges is the farther away you get from output measurements related to a sport specificity, the more difficult it is to aggregate TSS with hrTSS since hr is an input to the body system vs an output result of various body systems engaging in the sport movement… . Using power TSS or pace run TSS, swimTSS wrto a reference pace/power tries to improve by focusing on output (which incorporates movement efficiency). It may be simplistic, but considering simple RPE after doing the sport and trying to normalize this effort related to other sport efforts based on hr might re reasonable…or maybe simply considering RPE to be the normalizer for effort (RPE–> TSS) is a reasonable attempt. It’s hard to get around the specificity aspect effects. There might be some Triathlete research that delves deeper into this?
