MAP block too easy?

[JGreengrass]

I found Rue the Day easy on fresh numbers when it first came out, I asked on the forum and got a reply from Head Coach at the time Neal Henderson

NEW SUFFERFEST: Rue The Day is here!

Hi @JGreengrass! Overall, this session should be challenging but should not be nearly impossible to finish. Training isn’t always about hitting your maximum - in fact, only on occasion should a session put you at your limit…and this one generally should never put you there. It might be good to make sure that your current FTP and MAP settings are accurate…as generally speaking, most folks will see heart rate getting into Zone 4 by around the 5th or 6th effort during these kinds of sets/efforts. …

Revolver on fresh numbers is a much harder workout IF 0.9vs 0.86, I’m normally hitting my cThr after the 4th or 5th interval.

Yes both RTD and Revolver use the MAP value from your athlete profile to set the interval power. You could always try a HM as a less exhausting way of getting an idea of your current FTP and MAP scores.

Last thought. Are you sticking to the cadence targets, low cadence during HIIT leads to more muscular fatigue and lower HR.
