Endurance / Aerobic Training Recommended RPE Chart

New to endurance training, but I have been focusing on the last 6-months on endurance training (primarily running).

Been using RPE to autoregulate my training.

Just finished listening to Episode #117 of the BBM medicine podcast. I noticed there was a discrepancy in terms of recommended RPE Charts.

Rehab Team recommends 1-10 BORG scale RPE, however BBM templates and RPE article (What is RPE in Lifting? (Rate of Perceived Exertion Explained)) recommend a 6-10 scale (I’m assuming this is due to making for easier transferability from those who are used to RIR RPE programming from resistance training)

Seems like 1-10 Borg scale is more commonly used for endurance athletes, also more common in the literature and use for calculations for things like AC ratio (I know there are limitations to programming based off AC ratio.

Few questions:

  1. What is the recommended 1-10 Borg Scale for endurance training from the pain and rehab team based on what most endurance athletes are using and what is most represented in the literature.
  2. Is the internal RPE scale within Strava a good representative of that BORG 1-10 scale?
