OK this afternoon I went out checking only RP - targeting 230W (I realise values will differ between equipment, apps etc, but I would hope that when using the same app / appliance it will result in comparable (relative to) measurements on the same platform, be it this app, Polar V, Stryd etc) I hit it fairly easy on 6% gradients but had to almost sprint downhills to reach it. Now next question - when running on HR I could easily detect that I was eg getting into the anaerobic zone or that my (ave) HR is getting to high for reaching my objective, how do I map this to RP? My perhaps unfounded 'concern' is that RP might not take physiological (fatigue etc) factors into consideration, but will just indicate a number to hit which could result in you running yourself into the ground if you don't select the correct RP value? BTW - here is a review of the RP app : https://www.prorun.nl/runtech/hardloopvermogensmeters-13-running-power-estimator-iq-app/
