Red day after 5 days off the bike

I signed up to the Masters short power build plan which roughly gives 9-10 hours a week training. Im being informed of red days after threshold workouts (110 Tss) but the plan gives me a 150 minute endurance session the next day. Do I take a rest day or carry on? The AI feature kinda contradicts itself. Prior to this workout (Lions rock 3) I’d had 5 days enforced rest and was planning on doing an endurance ride the next day as this was in the calender. Trainerroad would have known the TSS for these workouts so why schedule them next to each other?

Hey @lyndon118 :slight_smile:

It looks like the Threshold effort was just enough to trigger a Red Day the following day.

What you are experiencing is our fatigue management system which goal is to monitor your training to help prevent long-term fatigue and unproductive workouts and tell you when you might be overdoing it with Red and Yellow days on your TrainerRoad Calendar. Just like a credit card, you have to pay the loan eventually, so it’s usually better to do it in small bits than all at once :sweat_smile:.

It’s important to note that as you train and get fitter, the amount of training you can take on changes, so a workout like Lions Rock 3 may trigger a Red Day today but not in the future. Even though you have a training plan that schedules all future workouts until the last day, it does not mean they are fixed. TR plans are dynamic and your recommended workouts can change day by day as it’s meant to meet you at your current fitness so you can progress productively.

They are, however, suggestions so you can accept them or decline as you see fit. At the end of the day, you know your body best. (But we recommend you take them :see_no_evil_monkey:)

You have to remember that you are still the coach and TR is just a software guide. You have to feel your legs and know if they are tired or not. It would be perfectly reasonable to do your endurance ride and take a rest the next day if it fit better with your schedule.

It was more that the training plan gives me the itinerary knowing the Tss in advance. A 2 hour endurance ride was scheduled in the plan, a day after a 2 hour tempo ride. So what triggered the red day? Why put those 2 rides together? I’ll take the rest day like they advised, I have a hard outside ride on Thursday so it’ll keep me fresher.

I understand what your concern is :slight_smile:

TrainerRoad schedules workouts based on your training history, goals, and progression levels. The plan assumes that you can complete the scheduled rides, but it also monitors accumulated fatigue, recent performance trends, and recovery needs in real time.

Here’s why your plan might have scheduled back-to-back endurance and tempo rides:

  1. Progressive Overload – Training stress is applied strategically to drive adaptation. TR schedules sessions that challenge you but are still within your capabilities.
  2. Energy System Development – A tempo ride followed by an endurance ride can be beneficial for building aerobic capacity and fatigue resistance, which are key for long-term improvement.
  3. Flexibility & Adaptability – The plan doesn’t assume that everyday plays out exactly as scheduled. If our fatigue management system thinks you show signs of fatigue, it adapts to prevent overtraining. (e.g., Red or Yellow Day).

In this case, your Threshold workout triggered a Red Day the following day, meaning the system recognized that while you could complete the rides, doing so might not be optimal for your overall progress. By taking the suggested rest, you’re prioritizing recovery, ensuring that your next hard workout is productive rather than a struggle.

Now, as I mentioned this workout may have triggered a Red Day today, but as you train and get fitter, this same workout could not trigger a Red Day in the future.

Think of the plan and the process of training like a coach watching out for your long-term gains rather than just checking off workouts. Much like a coach who sets out a plan for the season, they also check in with you to see how the training is going and if it needs adjustments based on how successfully you are completing workouts.

What was to happen if I was to ignore the workout change from RLGL?
Today I completed Asta and was originally scheduled Andrews.
Asta triggered a yellow day and TR adapted to Townsend.
Now Monday I have a rest day and Andrews vs Townsend is not that different.
I know my body can do the work and was thinking about doing Andrews anyway.
Normally I would respect RLGL

Hey @Kendogz161!

It looks like Townsend ended up triggering a Yellow Day on Monday, which is fine as you have the day off and tomorrow you’re good to go to resume training :slight_smile:

As I mentioned before, it’s up to you to accept the recommendations. In this case, I would say you made the right call as you have Monday off, and this week, you have entered a Recovery Week. If you had an interval day on Monday I would have accepted the adaptation.
