Your whole plan is generated up front. When you press Generate Full Plan, LeCoach creates every week and every workout for the entire plan (up to the 20-week maximum) and places them in your agenda immediately. Nothing is generated 'week by week' later.
Seeing fewer workouts than expected?
Check you're looking past the current week — scroll forward in the agenda.
If the plan generation was interrupted, the plan may not have been created at all — you'd see no plan at the top of your agenda. Create it again, and contact info@lecoach.app if it keeps failing.
A follow-up plan starts after your current plan ends; its workouts sit under their own section until they begin.
On your devices
Even though LeCoach and Intervals.icu hold the full plan, devices typically receive planned workouts for the near future only (that's how the platforms behave, not a LeCoach limit). Your Garmin or Zwift will always have the coming days ready.
Does the plan stay fixed for 20 weeks?
No — the plan is fully editable and continuously monitored (adaptive coaching). Generating everything up front means you can always see and judge the whole progression; adapting it as life happens is what the coach is for.
