Correct. The Adapt Forecast button only appears when an FAI plan is in play.
The button will show a red dot on it when you have drifted enough off-plan. For example, miss days, do a hard group ride when forecast called for easy endurance, etc.
The two modes operate as follows.
Mode 1 –
Continuous or Challenge = blank calendar where your day-to-day form (tired to fresh) dictates whether you are recommended endurance level or high intensity workouts against your selected Athlete Type (Focus Duration) and Improvement Rate (ramp rate).
The Training Pacer tracks a moving weighted average of your XSS over a rolling 7-day window.
Keep the needle within the 11am-1pm position and you are “on track”. Dip towards red and you are falling behind (ride more to catch up which might simply be a long weekend ride). Or push the needle past 2pm and you’re movint ahead of plan (ease up or take a rest day).
Consistently falling behind or pushing ahead? Adjust ramp rate to better match your schedule.
Target Date with 120 Day Program = blank calendar mode as above along with a phased progression running in background. I.e. Base phase to Build phase to Peak phase with a Taper alert the week prior to target date (so you arrive fresh for the event).
Mode 2 –
Target Date with a Goal or Event = Forecast AI pre-populated calendar consisting of mapped dosages of low and high intensity workouts between now and your target date.
Variable ramp rate and periodization is built into the plan itinerary.
Drift off course enough (schedule conflict, skip a day, high intensity instead of low, etc.) and a red dot appears on Adapt Forecast button. Run Adapt Forecast to re-balance your plan moving forward.
As long as the red dot doesn’t appear you remain on course similar to the Noon-ish position of the Training Pacer.
