This is what 24s @ 460W look like on my 2T setup, when the countdown of the previous section reaches 00:02s you “hit the wall”, so right before the interval. However, in the corresponding power track, the target wattage is reached 2s into the interval, never later than 3s in my experience. This workout was done using the desktop app (power smoothing set to 3s) connected via ANTplus-Dongle to the NEO 2T.
As your can see, I change my cadence right before and then ease into the interval.
In my understanding, “green” represents the signal sent to the trainer, “blue” is the planned workout, and “yellow” what’s actually measured. This is why “green” precedes “blue”, it’s meant to bring “blue” and “yellow” closer to each other. Obviously, “green” is what you feel during the workout, you are “hitting the wall” right before the “blue” interval. But in the end, you’d want to compare “blue” and “yellow”, planned vs executed, so you even only have 2s in the beginning of your 30s/30s.
Either is fine, just depends on what you’re connecting to… Laptop will take BT unless you have an ANT USB stick. Apple TV only takes BT. Most phones/tablets will take only BT.
Either is fine but make sure you are not using both at the same time – I had mistakenly paired my tacx trainer to both ant and bluetooth and observed some pretty weird and erratic behavior (like inability to match the prescribed interval wattage at the beginning of an interval no matter how hard I pushed the pedals). I was really starting to think that something might be wrong with my trainer till I noticed that I have no such problems when loading the workout on the phone app – then found the culprit! Using only bluetooth now.
I finally gave in and bought a Neo 2T,
Do I set up the trainer as a power meter on my garmin 530 or as a smart trainer when dual recording while on TrainerRoad?
There are two “types” of connection (when looking in their online manual): 1) one-way (the connected device only listens to the trainer, or, as you call it, connected as power meter) 2) two-way (the connected device listens and tells the trainer what to do next, it is connected as smart trainer). Moreover, you have two protocols/channels/means of connection ANT+ and Bluetooth LE. What you are trying to do is a so-called dual connection, when more than one device/head unit is connected to the trainer one-way or two-way. While ANT+ one-way channels allow for multiple connections/devices, ANT+ two-way channels and BLE one-way and two-way channels are exclusive (at least in the version used by NEO 2T). You could in theory establish 2 two-way connections to the NEO 2T by using both ANT+ and BLE, but that would achieve nothing, right?
TLDR: Connect the NEO 2T to your TrainerRoad device as smart trainer using either BLE or ANT+, and connect your Garmin 530 head unit as a power meter (ANT+ works best for me, I have the same setup as you), you’ll get all the Garmin metrics you need.
