As for a marketing name:
In the Mandalorian, the foundling is called Grogu… but we all know his real name is Baby Yoda. So you can call it what you like, but in the end it will always be “Red light / Green light.” 
I really can’t wait for this feature to come out, I just realized I’m in a fatigue hole yesterday after failing an easy sweet spot workout with my HR going way up into threshold. I didn’t see it coming though because I was feeling good up until after a VO2 workout on tuesday which went great. I’m really curious if RLGL would have seen this coming. I have a feeling it has to do with me botching my recovery week last week and doing way more hours than usual (classic mistake I know 
). Interestingly enough though my form is in the fresh zone on my PMC.
I’m curious if this can be predictive in addition to reactive. For example, if I could enter a a group ride I want to do on my calendar and estimate duration and IF if it would tell me that would be a no go based on my calendar or history.
Regarding “failed workouts,” do you think it has to do with AI (or train now) continuously pushing PL’s up until failure? Fatigue? Is it as simple as feeling thrashed and not choosing an alternate that is more achievable for how your day is going? Something else?
For me historically, it was Every Single Workout was way too hard, without exception. It’s taken me a long time to realize this was an issue…but getting a heart rate monitor made a world of difference, and made me realize every workout aside from easy endurance, was essentially a race pace dig up the last match, try not to throw up type of effort.
In my case it was definitely fatigue related. The last sweet spot workout I did was at the same power as this one, but my HR was through the roof this time. Usually adaptive training is really good at giving me the right workout but I definitely overdid the volume on my rest week.
This has kind of been my assumption as well. I think it’s how much your fatigue has increased based on the ride you completed vs your X week average. It could be Week over week or year over year. Something along those lines.
@Nate_Pearson Although I can’t say I’ve ever felt burned out or overcooked, I’m often forced to rearrange my workouts due to work that ends up really pushing me to my limits and I’ll occasionally downgrade a workout or two to get through the week. This past week is a perfect example. Perhaps I’m missing signals and would be curious how many yellow/red days I’ve been seeing.
If my scenario isn’t what you’re looking for, just ignore my selfish request!
Thanks and PS, I think this will be very useful for a lot of people
Always thought this. “Luckily” I rarely ride outside beyond commuting so Im quite easy to measure.
Don’t think I’ve genuinely been over trained more than twice since 2017, but it’s hard to assess oneself objectively. Especially with non-training factors, eg I skipped a ride today because I had two drinks last night. Or fail a threshold because I’m demoralised by work issues.
For a name, I’d suggest a non-ambiguous any-fool-can-understand term. “Red flag” works and is commonly used in training circles and everywhere.
Oh, there have been times I’ve felt burned out but I can’t remember exactly when. Not as much last year though. And, some of the burnout is due to factors outside of training so it’ll be interesting to see how this picks up on that.
As for name, maybe something like “Freshness Index” – has a positive spin to it.
@Nate_Pearson Will this feature also help in the opposite way and show where an athlete could maybe train more (assuming they have time)?
Is the aim to always have the calendar green or is having some amber and red days expected, but only extended periods an indicator or burn out?
If my calendar was green week after week could that indicate I could safely add extra training?
Man, it’s like you’re designing this for just me! I have a definite tendency to overdo it. Like, badly. I swear I am trying to behave these last three months. So far so good. But looking forward to more feedback like RLGL!
I’m really curious about how RLGL will work with TrainNow. What will it recommend on a red day? Nothing? Recovery ride?
RLGL name: Yeah Nah
Adaptive Training. Should be a feature of. One could assume part of AT is to endure I don’t dig a hole. But maybe I just lack creativity!
Appreciate Nate letting us all play along. This is fun. Thanks.
After understanding it better courtesy of this thread, I agree with you, seems like it’s a component within AT and whatever else TR is cooking up.
How’s about…

you mean marketing help from people who pay to use the product, rather than having pros who market for a living? lol i mean, it’s fine to play along but that’s what it is ultimately
Traffic Light system, by far the best idea (IMHO). 
Don’t underestimate the talent that hangs out on these boards.
While working for a small design agency in the 2008-2012 timeframe, I wrote a toss away line for an upstart bike manufacturer that became their de facto brand tagline for a while.
Not touting myself as a brand genius. I got lucky in that particular instance. But this is a pretty smart group around here.
