Hello all,
With CX coming I wanted to do some off road rides on the MTB and CX bike.
I will want to ride these bikes on my long endurance days.
Now my mountain bike doesn’t have a power meter and tell you the truth I don’t want to put one on that bike.
How would riding without power effect TR’s AI and training?
I’d say a spider or two sided pedal based powermeter are good options for the mountain bike.

I have a Power2Max on my primary & a stages left crank on my hardtail..
If I were going to do it over again I’d probably go with pedals.
Agreed. I had trouble getting what I needed from single sided power meters as well. Although it was better than nothing I guess.
One formula is “XTR w/o power < Deore” with power so it’s actually cheaper to have a power meter.

Since no on else will, I will try and answer the question. I can’t give an actual answer as to how TR’s systems will respond, but if you are doing Z2, heart rate and RPE are very good proxies. Just do the training as prescribed and it will be fine.

Thanks, the thing with the mountain biking the varying terrain makes it hard to stay in that endurance zone but I feel like the bike skills I get from it help with CX races.
I can find a loop that more zone 2 focus and go from there.
Yeah. I have a PM on my mtb not to do workouts but rather to help quantify performance and keep track of IF, TSS, etc.. Doing workouts, it’s hard enough to stay reasonably in zones on a roads. I don’t think I could do it at all on the trails I ride. I use a Sigeyi spider PM on the mtb.
I’ve been trying to figure out how TR treats anything that’s outdoor riding and haven’t yet. When I’ve queried TR, I got conflicting and sometimes obviously wrong answers on this. It seems to be a work in progress that keeps evolving.

That’s exactly what I was thinking about,
i don’t want TR to start adapting downward or start lowing my FTP because it sees a MTB ride without power as not putting in the work.
To my MTB was always fun so I was hesitant about putting any sensors on that bike.
For now I just kept it at speed and heart rate sensor for my MTB rides.

You don’t need a Powermeter. If you don’t want one on the mtb just find a segment that you can do safely (good sight lines to avoid a head-on) and rip it. Time your segment. Do reps of that segment. Work on dialing in rpe, etc.
How will it impact TR not having a Powermeter? Your TSS will be estimated by your heart rate (if you set that up) which I have found to inflate a bit on the mtb (probably due to my heart rate staying elevated on descents when I am “coasting”). Outside of that no idea on the inner working of the AI FTP stuff. You won’t have power or IF so my guess is the “unstructured-ness” of MTB may lower your FTP, but that might happen even if you have a Powermeter. In the end more data is better, but I am sure you’ll be fine. Just *grip it and rip it!”

Hey @Kendogz161 
So cool you’ll be racing CX!
As @Jolyzara mentioned, if you don’t have a power meter then just make sure you’re rides are receiving TSS so they can be appropriately taken into account: How to Estimate Training Stress Without Power Data

Thank you for the info Caro, I wasn’t sure if no power rides would have thew off TR.
Is the TSS estimate old before update? I don’t see the 1-10 RPE chart, I’m guessing the normal TR RPE 1-5 chart does the same thing now.
Hey @Kendogz161 can you take a screenshot of what you are seeing? The RPE scale should be 1-10 when estimating TSS.
Caro, never mind, I found out what I did wrong.
I see it has RPE base TSS or heart rate base options.
