Since you’re new, you should conduct an all-out 20 minute time trial. Your zones may still be somewhat slower than you’re used to, but you’ll have more and better confirmation that they’re right.
Thanks for the replies. I learned that you can enter it either way and the FTP and zones will come out the same. I also realized that Training Peaks will conduct the 80/20 zone calculations without having to copy them.
Great points Brian. I’m not 100% sure I’ll take to rowing either. I’m going to give it a shot to see what the appeal is and will look into cycling also.
Speaking as a fairly new runner who also suffered through calf issues, you should visit your local running store to make sure you have the proper shoe type and have a coach look at your running style and gait. In my case, I had problems with both.
I’ve been using 80/20 while eating Keto OMAD for months to lose some weight with very good energy and results. Although I’m not a competitive runner, I wouldn’t hesitate to give it a try for racing – many people do.
