This is a common problem that I see in some of the athletes I work with. They feel the same way about the pace of these Level 1 workouts that they are trying to fit within a certain HR range.
You could try to factor in your Resting heart rate to your zones. The Karvonen method is used to sometimes give a more accurate representation of your zones.
Target Heart Rate = ((max HR − resting HR) × %Intensity) + resting HR example
I would also suggest a couple workouts to do.
The main one that I like doing for a workout over 2 hours is one that you switch off running and hiking/ski walking every 15 minutes. This will let you run at the pace you find appropriate but might be slightly higher in heart rate than your estimated Level 1 is. With the hiking/ski walking your overall heart rate of the workout will hopefully end up in your ideal range. If you do this workout for a period of time you’ll hopefully see your heart rates begin to drop.
The other simple option that is good this time of year is just to go hike. Long sustained hiking whether it be up a mountain or through the woods can be very beneficial.
