I’ve had several connection failures between my Kickr V6 and Zwift since Wahoo pushed a firmware update on 01-JUN. The trainer is connected to the computer via wired ethernet on a dedicated DirCon network. Super solid for nearly a year of operation. Wahoo is aware of the issue and is reportedly working on a fix, but I digress.
Today, there was a failure during a recovery following a successful over-under set (Bounty). I paused the workout to look at the connection settings and get the trainer reconnected. I was offline for ~1 minute. TR identified this as a pause in the workout, and lowered my workout levels, but not in a meaningful way.
Earlier this week I had a dropout during a vo2max interval. TR identified the pause, and lowered my workout levels and the overall session level from 5.6 to 5.3 (Garraun). If not for the hardware connection failure, I would have fully complied with the workout and achieved 5.6.
@eddie can TR distinguish hardware connection failures and intentional pauses/rests? Can hardware failures be flagged during the survey?
Here is today’s session. The connection failure is ~56 minutes in.
I’ve had an uptick of Zwift drops lately too (Kickr V6). I don’t mind so much that it dings my TR scores, but it irks me that it means I don’t get my little Zwift workout star/xp bonus.
I have had a similar issue. All of sudden there is no resistance for a bit.
If it lowers my TR score it’s ok. Even though I could have done the workout with no pauses, the equipment did not let me. Can not get credit for something I did not do.
Maybe they will fix the issue soon.
Maybe I’m out to lunch here, but my understanding would be, it doesn’t really matter.
Let’s say someone has a 2 x 20 minute interval, and the second one gets turned into a 2 x 10 minute effort wit ha 2 minute stop in the middle.
Whether that’s because you had a kid puke, a hardware stop, or decided your legs were just too tired, the training effect is still from doing 2 x 10 minutes, and when the back end looks at what to sort of of “credit” you for, you had the same dose of training, regardless of the reason for the stop.
The survey however tells them how easy or hard it was. If it was all out to the point where you were forced to stop for rest, then you’d mark it as all out or very hard.
If it was moderate, and just happened to have that stop, mark it as such, and then it’ll treat say the 7.6 credited ( rather than the 8.0 planned ) as a moderate effort effort and training continues as normal.
So in essence properly doing the surveys should take care of the issue, and as far as training dose goes, whether a 20 minute effort turned into a 2 x 10 because of a hardware issue, or it being too hard, you still “did” 2 x 10 and didn’t actually do 20 straight which would credit for a different overall training input, and the surveys basically tell the difference.
No, it doesn’t unfortunately. Mine dropped out and was unworkable - the survey score didn’t really change anything and predicted FTP dropped by 10W. Support have been awesome, so doing some TR fixes but sounds like it is at the Wahoo end. Same problem by the way - update this week Kickr6 and connection which had been stable since it was new (2 years-ish)
Yes, but 2x10 with a 2 minute break has less effect than the single 20min interval. Taking a break reduces the effect. IDK by how much, and many will argue it’s small, but it does reduce it.
Three connection failures during today’s Keeper session: one at the end of the second recovery, two during the fifth interval.
I did a makeup interval after the timed workout which appears to have restored the workout levels and increased the overall compliance from 5.4 to 5.6.
Also, to clarify my initial post, I’m not suggesting that users should receive credit for incomplete intervals. Rather, I’m curious if the model can distinguish between user and external interruptions or outliers. This could be connection failures or inaccurate power reported by a smart trainer. It seems that an athletes profile would benefit from the model accounting for errors like these.
Failures at 0:27:00 and 0:50:00. Really didn’t want to do that makeup interval

I agree with most of what @dfquigley is saying here.
Training interruptions that are out of your control are unfortunate, but I wouldn’t worry about them, as there’s not much you can do. In the grand scheme of things, they aren’t going to make a major difference in your training unless they become a chronic issue.
If you fail a workout, hardware is an option in the struggle survey, though.
