Week 1 was about getting into a groove, getting that niggling rib injury to settle and trying not to get carried away. Week 2 has been about managing the increasingly achy shoulders and fatiguing body. I made what I thought was a sensible decision to do as much bilateral breathing as possible in the first week. Partly because I have always been nagged by various swim coaches that my one-sided breathing was the cause of various right shoulder issues, and partly because I was starting this 30 days of marathon swimming with an existing rib and back injury on my right side. So one week in I was pleased that the rib and back were settling but I was struggling big time with an increasingly painful left shoulder. The only thing I was doing differently was the bilateral breathing so I ditched it and went back to just breathing to the left side. Can't say the left shoulder is fixed but it has stopped getting worse so hopefully it will stay at this level for the next 2 weeks. On the plus side I'm starting to sleep better, I think that is the increasing fatigue catching up with me. Halfway tomorrow.
