Took a look back and it just fits in with my plan, threshold followed by yellow endurance, V02 followed by yellow endurance. Seems like it just shows yellow after every high TSS. Not sure I need yellow light to tell me whatโs already in my plan. But I guess if I was feeling like doing a back to back threshold itโs reminding me to chill.
I just activated it in Early Access and it immediately suggested adapting my workout today from a V02 workout to an Endurance workout. This V02 workout today is one that I deferred from yesterday because I was feeling tired (I did extra cycling and activity on the weekend) and so I decided I should rest. I moved the workout to today.
So, I take this to mean that the RLGL is working in the background. I feel pretty good today so I did skip the recommended adaptation. Iโm still going to do the V02 workout tonight if only to satiate my anxiety to stay on plan beta test the new RLGL feature.
UPDATE EDIT: The color coding just came through and yesterday was a red and today was a yellow. So, it seems to track with how Iโve been feeling. Also, it often has a red day after days Iโve had bigger outdoor rides too.
After 5 days of red the 6th should be plaid or something.
No, I just turned it on using the webpage in early access.
I do use the TestFlight app if you know what Iโm talking about?
Itโs the App we used for early access things back when adaptive training first came out. If you donโt have that maybe someone can guide you towards downloading it. I honestly donโt remember how to at this point in time.
It should lock you out of all cycling apps on your PC and drain the battery on your garmin ![]()

The AI needs to brick your power meter until you can be trusted to train again.
Another great work! Thanks!
Any chance we can get an alternate color option for the color blind?
Donโt be so sure, there is more in your ride data than it initially appears, for example respiration rate, cadence shifting lower/higher during hard intervals, power line smoothness (even with ERG mode), etc.
Looking at historical rides, it looks spot on for me. I am usually quite consistent high volume rider. Have followed TR or my own plans, often stacking hard days back-to-back. And RLGL shows red on days where I did took day off due fatigue, even if TSB wasnโt too much off.
Not sure what youโre doing because Iโve been on HV plans for years and increased my volume to 1,000 TSS weeks and have ZERO red days (RLGL telling me to take a rest day). The only thing I can guess is you have big TSS days that are far above your normal volume.
@ming - I think this is a really important question
Indeed, it is pretty cool to zoom out as much as possible and check your overall patterns. I wish it would be official TR view/feature.

Ironically, the entire lack of
in use still doesnโt alter the impact of Red Light
Yellow Light
(which is the more pragmatic name, apparently) ![]()
Happens to the best of us. ![]()
But really now you can try to prevent that! ![]()
Yeah, donโt want to be missing key intensity sessions, would rather have it postponed a day or something
Yes, you can accept or reject them.
And yes, it would be cool to see them on that graph. Itโs already pretty busy but if there was an option to turn it on that would be cool.
With the new calendar thereโs an improved graph that shows races, too!
This doesnโt use CTL/ATL/TSB. It also doesnโt have anything to do with TRโs plans. Itโs a separate fatigue monitor.
In your case, it might be better to take a rest day each week. Especially since youโre ramping up volume from what looks like a lot of time off.
Going a bit slower in your TSS ramping will make you more successful in the long term.
Wow, this RLGL feature is fantastic, and thank you TR team! Viewing my previous seasons, I was surprised to find that before instances of feeling burned out, there were mostly yellow days rather than red ones.
I have a few questions regarding this feature:
- Currently, Iโm following the general base #3 mid-volume plan, and upon reviewing my history, I noticed some yellow days (and red days too!). Is it acceptable if my rest day coincides with a yellow day, or does a yellow day falling on a rest day suggest I might be pushing too hard?
-
If I anticipate having a yellow day after several days of workouts, will adaptive training determine the duration of the endurance ride on that day or is this something I can choose?
-
Suppose I opt for complete rest on a yellow day instead of following the recommended endurance ride as suggested by AT. Will this result in loss of gains, or is the rest likely to be beneficial?
-
Additionally, does the RLGL feature take into consideration that rest days may not always involve complete rest, and individuals may have tasks requiring prolonged standing or walking? For example, yesterday was a yellow day, and although I didnโt do any TR workouts, I had to spend a significant amount of time walking as part of my work, which wasnโt recorded on Strava. Does RLGL account for external factors like these?
Thank you!
Will RLGL adaptations be separate from โregularโ AT adaptations?
So if I decide I want to dig my own grave and ignore RLGL suggestions but still want the AT adaptations will they be separate prompts? Or will it be an all or none situation?
It taking into account training history, but it doesnโt have HRV or sleep (yet). I removed the mention of biometrics from the post.
