To begin with, make sure your max HR and zones are all reasonably correct. You say your max is 194, but it's not uncommon for the real max to be a decent amount higher than what you see in regular runs, unless you truly pushed yourself to the absolute limit.
I'd use lactate threshold heart rate to calculate your zones, if your hardware/software supports it. Prefer a proper strap over a watch as well if possible.
Beyond that, you're just going to have to run slower than what you are used to, to stay in the lower zones. Try to do it with good technique and reasonably high cadence. If you can't run slow enough, throw in some walking in between to get your HR down.
