Hey there!
I totally agree that Track racing is a bit different than crit racing since the events are MUCH shorter.
In these cases, we recommend manually changing the Build and Specialty plans to the following:
Short Course:
Optimal Training Progression
Base: Sweet Spot Base I&II
Build: Short Power Build
Specialty: Gravity
Long Course: (10+ minutes)
Optimal Training Progression
Base: Sweet Spot Base I&II
Build: Sustained Power Build
Specialty: 40K TT
One day, I would really like to see this integrated into Plan Builder as well, it’s just a matter of Development Resources going full tilt towards Adaptive Training at the moment
