I had track training last night. (I found a well marked, nice track!) 4x1000, same intervals as two weeks ago (I'm repeating 2 weeks of training). It actually went quite a bit better than last time. My goal was to run 4:01 repeats - two weeks ago I fell slightly short on the last interval. Last night: 3:58, 4:01, 3:59, 3:58. Either my tempos last week were the exception, or my lactate threshold is disproportionally weaker than my other parameters. In either case, I will know what to do.
