Hi,
This will be my first season in xert. I would like to start with a Base period, but my first target event is not until june. What would be the best way to do this?
I have thought of starting the Base-Build-Peak plan, but after finishing the Base phase, switch to adaptive training. Any better option? From what I have read, adaptive from the beginning might give me too much intensity at the start.
Try the periodisarion slider. Periodization Level – Xert
With XATA the Base-Build-Peak (BBP) option defaults to 120 days out from today.
If the target event were on June 15th the traditional base period (all endurance) in BBP couldn’t begin until February 16th.
In the meantime, you could select XATA Continuous, set improvement rate to Off-Season, and ride however you like. That might include less cycling and more gym work in preparation for your progression starting in February.
You could set Focus Duration to 20-minute power (Sprint TT) for the least intensity recommended on HIT days,
In XATA Continuous mode you’re in charge. You’ll get adaptive training advice based on calculated form (v.tired to v.fresh) but you can choose your own path and over-ride the advice when you want. You can be selective about which workouts you choose and their level of difficulty.
If you instead generate an XFAI forecast with June 15th as the target date the periodization logic will kick in and show a dip to start with.
Here’s an example test forecast I ran for a June 15th Hilly Road Race 3+ hours.
Notice how the Focus Duration starts out low (dip to easy; more LIT) then zeroes in on Mixed Puncheur (4 minute power) HIT in June.
You can run your own test scenarios. You don’t need to save them. Zoom in out on chart and hover over each matchstick to see details. Also isolate the chart entries by tapping on the key below the chart. Example (60 day Goal):
XATA follows a more traditional phased progression, but the same principles apply and run in background with a blank calendar. Click here to see how Focus changes during a BBP progression.
I posted a chart of XFAI/XATA differences here – Forecast AI vs Continuous Adaptive — better load & recovery management? - Training - Xert Community Forum
With this many months out from your event date you could experiment and try all of the above. 
I.e. flip between XATA and XFAI with different settings and note what each does over a week or two. Just keep in mind you want your XFAI plan or XATA BBP progression to include enough wiggle room to support a reasonable rise in TL over the term. No need to reach max weekly hours until Peak phase.
Enjoy the ride.
How many stars do you currently have in your Xert profile (next to your name)?
Easiest option would likely be to use XATA and ride a lot of “Zone 2”
I have found that using XATA does help quite a bit in building your training up sustainably from where you are now. Depending on your current training load, I’d consider something like Moderate - 2 or Aggressive - 1 as a solid starting place. Aim to keep the pacer needle near the 12 o’clock position and you’ll be building fitness steady throughout the winter!
The amount of intensity was too much or the actual intervals themselves? How much High/Peak XSS you’ll be recommended will be based on your unique High/Peak training loads. If they’re well-trained, then you can handle more intensity than someone that doesn’t have well-trained HIE/PP systems.
The intervals within in Xert’s workouts often tend to be higher than what you’ll find in other platforms. This is because we don’t base all our intervals on %FTP. Most other platforms will have pretty small window where training is prescribed (mostly 70-130% FTP), while Xert will have everything from endurance (70-80%LTP) all the way up to high-power sprints near your Peak Power, depending on what your goals as an athlete are.
Best of luck with your training!
