I recently did an unstructured outdoor ride and when I finished, TR asked me if I still planned to do the scheduled structured ride.
As I understand it, it’s to add anticipated future solo and group rides to your plan so the plan is built considering these. e.g. if you plan to participate in a group ride every Sat, then add those to the plan and the plan will be built taking that into consideration.
Yes. That’s a relatively new feature. In the past I had to either delete the plan’s workout for that day or wait until the next day for it to expire. Now it preempts that by asking.
FWIW
This is how I combine outside WOs, solo rides and dynamic endurance:
- WOs are done according to plan - but outside. I use the warmup to get to “my interval place”. Dependent on the intervalls this might mean a longer warmup (my 6-15 min hill is about 25min away), or a detour (everything up to 6 min is “at my doorstep”).
- During intervals is glance at my avg and 3 sec power - trying to keep it smooth. If traffic, or anything else (like my power meter dropping out, gearing mishaps), throws the average a bit off I do not chase to get it back up - I just focus on the 3 sec average.
- My current plan includes one “fun day” on the mtb. As I understand it, TR uses this mostly for it’s fatigue management. So it make sense to schedule them. I only av HR on the mtb so my assumption is that it affects my AIFTP, but it’s not “high value data” (as data from a power meter).
- I use dynamic endurance to plan my longer rides. I do not schedule these as outside rides, but rather use the schedule wo to plan my route and a rough IF.
I think this approach is based on the advice from TR. It works for me at least, but I’m not racing. Just want to be fit, and enjoy my rides. If any of the TR employees looks at this and goes “no way, you’re doing it all wrong!” - please let me know 
Sample training week (I change to outside just prior, as I (too) often have to move stuff around):
Sample 3*12 O/U:
Sample dynamic endurance 3 hour:
and have a manually set FTP that’s maybe ~5w lower than what I’d classify as “real” and 12W lower than my last AIFTP detection.
This is certainly why you’re starting with slightly higher-level threshold workouts. 
Manually setting your FTP will change the workouts we prescribe, but we’ll still give you workouts that we think are appropriate based on your recent training data.
Since you’re telling TR that your FTP is lower than it thinks, it’s giving you slightly higher-level workouts to compensate.
Yes, but the point was if I accept TR’s FTP it has put me at 4.6 and 5.2 athlete levels, not benchmarked to a level 3 (ish) which was the discussion
Ahh, I thought you were saying that it puts you at those levels when you set a lower FTP manually…
I wonder if this happens in your case because that detection was in the past and you’ve been training/progressing since..
Something interesting happened for me today. AIFTP Detection reversed course, went from a little high (342), to maybe ~5W low (330) but really a little more accurate on the conservative side (My read is 335 right now, maybe a little higher on a good day outside). With my Athlete Levels ending ending up staying here regardless if I’m at 330 or 335:
Just so you know where I stand, I think this is a good thing. A couple more relevant efforts on my side and I bet it’d be dead on. But something in my training and the work I’m doing actually made it move closer for me. But, definitely not looking to calibrate me down to a lower Threshold Athlete Level, so that’s definitely not always a thing.
Again, these are custom workouts, custom plan, and I’m not always following them to a T, so there is that caveat.
But, overall tracking a bit better for me.
Interesting. I know you’re a unique case, but if you find anything that you think might be guiding things into the right place, let me know. 
I’ll give you my wager. I’ve been doing longer efforts right at or near my actual FTP.
My last workout was prescribed as 2-3 x 20 minutes at 100% of FTP. (Coach gave me a target of 10-15 minutes for the third interval for 55 total minutes at threshold, so TR would actually see that as not completing the third interval in that case, and I also do these on a range so may turn down or even up depending on the day)
So, you have workouts that are very close to my threshold limit and definitely big / hard workouts that I may tone down on a given day.
On that one last weekend I did 2x20, 1x10 between 330 and 335. And, I’ve got it coming up again this Saturday where I’ll try and push closer to 335 for 60 min total TiZ. (Outside last weekend and hopefully this weekend too)
So very close to my actual threshold limit for longer durations is probably giving the system a different sort of “good data”. Who knows if it changes again, but maybe the system is “learning” me a bit better with this type of work?
If you want to peruse my calendar - go ahead, just keep in mind there’s sometime some context behind the way I’m executing workouts as they are custom.
