[Feature Request] Fuzziness in Interval Summaries



The one thing that I still find frustrating with a dumb trainer is that I routinely “fail” short intervals (5 seconds, for example). For example, I recently did Ebbets and “failed” the sprints during the last interval. It turns out though, if I just move the interval by one second, I didn’t fail them.

With interval search, I can now just search within the workout (let’s say by the minimum power for the lowest sprint interval and 5 seconds duration) and I get a list of all the 5 second-sprints. Then I can compare to the intervals.

What would be super cool would be if TR could do that work automatically by applying a certain fuzziness to the intervals. So if in the workout summary it lists Sprint 12 as 350/375 or whatever, it could just look 1-2 seconds to the right and see if that changes the power upwards. Does that make sense?

That totally makes sense and in my opinion, this sounds like a great idea. It’s tough to nail down short intervals like this on a dumb trainer, even though you’re still doing the required work you’re off by a few seconds. I’ve passed your suggestion on to our product management team!


I second this;

Dumb trainer/ virtual power;

I tend to treat intervals as if they start ~5-7 seconds earlier than they do to get around this.

Coincidentally, there is no such lag when you let off the power (evil cyclery god’s I’m looking at you). So all sprint intervals tend to get an extra ~5 sec of duration tacked on.

Obviously this is tricky with shorter intervals, especially ~30 sec and under, where extending the intervals ~5 sec is actually a significant amount of extra training load.

Ohh, and thanks for an amazing product.

5 stars I dare say :wink:


Hi @larry would it be possible to add to the search an interval range. For now you can search time spent above x Watts, but would be nice to search it in range mode as well.

Have you thought about it?



@larry also, on the time frame, although it says time longer than X when you search it limits the interval for the specific time. Is it possible to expand this as well?



+1 for this. It’s not just a case for dump trainers but also ERG mode (some trainers kick in earlier or later).


@larry @Bryce
This feature request would be very handy. Some additional idea:
I know you’re not too much into HR (at least as far as live data is concerned) but could you apply this also for the HR average of the intervals in the interval list? So looking up to 30 seconds (for very short intervals you might take less seconds) to the right and showing the max average HR for the interval duration?
HR is deferred and in the graph you always see those HR waves deferred to the power spikesof the intervals.
With an interval of 2 min my average HR of 0:00 - 2:00 is not as interesting to me as the average HR of 0:15 - 2:15 for example (or maybe just the last part like 1:00 - 2:15)…

If the code for this feature request for power is in place, the same code/principle could be used for HR.

@Nate Am I making sense here? Which part of the HR graph do you look at for intervals? Wouldn’t you like to see the matching deferred average HR for an interval in the interval list?


Hey @Rizzi! Thanks for your feedback! You’re right, we’re not big on HR and I wouldn’t be giving you a fair response if I told you that we’d look into doing this. For the moment, there’s no code in place to support this feature request on the power side, but after speaking to our app product manager, it sounds like we have something in mind that will take care of this and is on the road map. No such luck on the HR side, at least how things stand right now.

Hope this helps!


I like the spirit of this post:

If my power lags a bit give me credit for not failing the workout; especially on super spikes workouts as those are hard to hit perfectly.

I think we can do the above automatically.
