Long Distance RPE 6

I notice a lot of the runs in the long distance plan are RPE 6. I take this to mean a Zone 3 HR? In line with polarised training, are long runs not meant to be Zone 2 for Iron distance? Sorry if I’m being really thick.

I tend to go by workout description, “easy to moderate” effort.
For me that’s below zone 3.

Here’s a link to a comparison of the TrainerRoad RPE with other metrics:


It’s just an easy run, or Zone 2. I generally agree with the table posted by @schmidt.

Speaking of the subject of RPE vs. intensity zones, there’s been some discussion which yours truly initiated. Some people will tell you that RPE X could be equilvalent to different paces depending on how long you’re running at the given intensity.
