RPE or Heart Rate for cardio training?

[Charlie Golf]

Which method do you utilize or have you found most effective when doing your cardio workouts? RPE (Rate of Perceived Exertion) or Target Heart Rate?

I've pretty much always used HR but recently have noticed that working in my zone it sometimes seems like I could go forever or carry on a normal conversation while working out.

I use both. I relate my hour to rpe and then monitor my hour. Eg. To develop endurance, my current priority, I want to stay in the borg rpe range of 13 - 15 for 30+ minutes. For me that is a heart rate of 135-145.

I use RPE, simply because it's much easier. I just don't see that I would get that much more out of it by measuring heart rate. I think RPE works just fine
