Decided to stick with an easier stroke sequence today, but I still ended up working a bit too hard (judging by HR and RPE).
Today I did 6 repeats of 2′ @ 18, 2′ @ 19, 2′ @ 20, 2′ @ 19, 2′ @ 18. At 10W per stroke, this should yield about a 188W (2:03.0 pace). As I usually do, I ended up about 4W above that.
Tomorrow: Another go at the CTC, target pace 1:41.
