A couple quick points, with more details in the linked post from another thread.
I sometimes have a handful of craisins or raisins to keep my stomach quiet before harder workouts (non-fasted).
I also need 15 minutes to warm up, usually 55-75%, stepping up 5% every three minutes. I modify any TR workout in Workout Creator that doesn’t have at least 12 minutes. My cadence is also slower than normal when I first start so I do three 30-second quick leg spins above 100 rpm during the warm up, usually one each at 55%, 60%, and 65%.
