Still struggling with the breathing. I can walk single flights of stairs and moderate hills but still have problems.
Objective: Continue acclimatizing.
Swam about 12 laps (I think) in a little less than 30 minutes. I wasn’t tired, but I couldn’t breathe at all. Each full lap of freestyle made the pulse beat in my temples, and I wound up doing alternating lengths of freestyle and breast stroke.
This should have been a back day, so the swimming sort of counts.
