Rock Steady – Week 3

I still struggled to complete 4×16 minutes at LT with 4-minute rest between set.  After the 3rd set, it took ~2’40” for my heart rate to drop below 66%.  The puddle of sweat beneath my bike was getting larger as I struggled to maintain my HR between 80-85%.  My breathing labored, my cadence slowed, and my form was getting uglier by the second.  Finally, I slowed to catch my breath, letting my HR to drop below LT for 3 minutes, long enough to give it another go to finish it strong.

It is too soon to suggest that I’ve improved over the last two weeks, but the data is promising.
