UPDATE: Did Clouds Rest +2 (30/15 at 130%). Too much. Made it through the first set, but was seeing stars. Going from 20s to 15s of recovery just made it that much tougher. Plus it means two extra intervals get snuck into the set (16 instead of 14); nothing breaks my will more than realizing I have two more intervals to go than I had anticipated.
So I reduced intensity for the second set by 3%, but still skipped two intervals in the middle.
Third set I rallied and didn’t skip any intervals. I nudged the intensity down by 5% (total, not in addition to the prior 3% reduction), and that seemed to get at a sustainable effort level for these 11:40 sets.
All told the workload wasn’t any higher than last week (due to reduced intensity and the skipped intervals in the second set) but arguably I extended the total time I spent working at/near aerobic capacity. But who really knows? All I know for sure is there was more fear and intimidation this week than last week.
