I have no cardiac issues and have been preparing for a Rainier attempt for two years. I begin the 16 week training plan this March, but overall have been using the TFNA training logic for the last two years. This is why I am spending about 4-8 hours a week training, with a lot of  “Level 2” aerobic box steps, and I have been hiking on various hikes.

The beta-blocker is for a movement disorder, which you can probably Google “Beta-Block & Movement Disorder” and find out the condition I was born with. I don’t need them, but use them to control my movement disorder. However, as I have been training with them for the last two years, I think it makes more sense to continuing my training and attempt with them.

I need to reread your reply to ensure I understand everything, but I will reply with some answers.

Using the MAF HR Forumla, my threshold is about 147 bpm. I know this probably isn’t the best technique, but when I train I am using my Garmin Fenix 6 to track HR/Stats and have been using the default heart rate zones. I know Scott is a big fan of nose breathing, and using this technique I can nose breathe at a higher HR than what is included above, probably around 145 bpm. However, that HR does not feel sustainable which is why the MAF HR formula does not seem correct to what conditioning with beta blockers.

As for RPE, I can say the 125 bpm that you can see in my workout above is sustainable, I am slowly increasing time each month. But at this point I can keep that pace for 90 minutes and potentially longer.
