I am new to 80/20 and just started the maintenance running plan using training peaks. I did a 20 minute time trial test to establish my LTHR using the average HR of the last 15 minutes.
The 80/20 zone calculator puts the top end of Zone 3 at 100% of the LTHR.
I’m scheduled to do a fast finish run tomorrow. The note in the workout says “Note that CV = Critical Velocity, which is the fastest pace you could sustain for 30 minutes and falls toward the low end of Zone 4.”
Zone 4 starts at 102% of my LTHR. If I can only manage 100% for 20 minutes, how am I to reach 102% for 30 minutes?
Maybe I’m missing something? Thanks
