Erg mode in Build me up plan


(Tom Sierens) #1

I have been using zwift for 3 years together with my Elite smart B+.
However since I am using the build me up workout plan the trainer does not regulate the wattage anymore.
This is only the case in the workout plan and not in other workouts.

This is specifically an issue when needing to put high wattage at low cadence.

Anyone any idea?

Hi Tom,

In order to investigate, can you please specify the exact workout or workouts where you encountered wattage problems in the Build Me Up Training Plan. If you let me know what workout(s) has the problem, I can take a closer look at the wattage and cadence targets in the workout, and let you know what I find. Thanks!

Hi again Tom,

I had a look at the Halvfems and Orange Unicorn workouts and didn’t see anything out of the ordinary, though admittedly one can’t see information beyond a visual representation of the segments and the wattage targets.

If you’re having a hard time reaching your wattage targets at low cadence, it almost sounds like ERG mode is not working correctly for you. ERG should increase your resistance to help you reach the high wattage targets at a low cadence. For example, if the resistance is very high, you won’t be able to pedal very fast (low cadence), but pushing against the difficult resistance should generate higher wattage. If that is not happening for you consistently, then it would appear there’s a technical issue preventing ERG mode from working the way it’s supposed to work.

Also, you’re not changing gears during your rides, are you? If you’re using ERG mode, you shouldn’t need to change gears on the bike. Just set your bike in a neutral gear, keep an even and steady cadence, and let the smart trainer do all the work for controlling your resistance.

Hi Steven,

That is what I am thinking as well. ERG is not working (well) when doing these exercises.
However I started a basic one and there ERG is working fine.
Also The trainer and app seem to think ERG is enabled.
I tried adjusting the difficulty but that didnt help.
Not sure what to do.

Regards
Tom

Hey Tom, can you send us a support conversation with your log files the next time you try those specific workouts? We want to see if there are any slight dropouts between your trainer and Zwift.

Was there any resolution to this? I’m having the exact same issue on this particular workout. Thanks

Had erg mode issues with training session Method in Build me up. The wattage was getting stuck and not changing with each interval. I’ve only seen this in the Method workout in Build me up so fare. I’ve been going to the Bluetooth Pair command to disconnect and reconnect to get around this.

Also seeing a similar issue after starting the build me up plan. Erg shows it is on in the app but trainer does not respond

Hello All,
I did find a workaround by some pointers by the helpdesk.
My issue was with regards to my ANT connectivity. (only during the build me up training)
By connecting the trainer with the companion app by bluetooth, I was able to succesfully use ERG mode during the build me up training.

Regards
Tom

Morning. I’m on the build me up program too. No issues so far until this morning. On the Halvfems programme I got to the first step ups and at the same point the trainer lost connection to zwift so no power or movement was recorded. I restarted and it happened again at the same spot.

So restarted again but changed the course to another loop in London and it was fine. However, halfway through the same thing happened and it lost connection again at one of the higher wattage intervals. I noticed that the companion app had disconnected so I paused the workout. Restarted the companion app and it seemed to be fine.

However on the recovery sections which were supposed to be 120 watts for 4 mins, the ERG stuck at 190 watts or thereabouts so I had to grind it out. Similarly the cool down resistance steps didn’t work so the wattage was again fixed at 190.

Frustrating and painful in equal measures!

Thanks.

For clarity. I’m using an Apple TV 4K with a wahoo kickr and wahoo tickr heart monitor.

Hi Rick, ERG has a set range that it can work for a specific gear ratio, did you try to use a different gear?


(Rick Hirst (SPCC)) #14

Hi Gerrie
I did try other gears but the wattage remained at 190 ish and the resistance continued, i just had to deal with the cadence best i could.
Felt like the connection between the designed workout plan (120w) and trainer wasn’t in sync.
