Having found Week 4 easier than I had been dreading, I launched into Week 5 this morning brimming with confidence, which I quickly realised was entirely misplaced. It was really tough, the worst part being that I couldn't find a good rhythm - my pace just didn't fit with the music and I struggled to concentrate on my breathing, which is usually the way I get through the runs. Almost gave up in the last 5 min run, when suddenly at the half way mark, a new piece of music started that I could finally match my rhythm to and suddenly I felt like I could run for miles (not really, you understand, just in my head!) and I even manage to accelerate my pace for the last 90 seconds. Feeling much relieved that I made it through, but will approach the next run with trepidation - do I need to worry about the music for W5 R2?
