You can lengthen the warmup or cooldown of any TrainerRoad workout on the fly with the Extend Warmup/Cooldown feature.
Adaptive Training doesn’t currently take these extensions into consideration when evaluating your workout, so using the Extend Warmup/Cooldown feature will not increase the Workout Levels of a given workout. We plan to address this with future product updates.
If you want to add additional training time after your prescribed workout that Adaptive Training will fully recognize, we recommend selecting a separate workout and loading that.
