I procrastinated on going running today but when I did go out it was actually pretty good. I feel like I'm getting back to a stage where I'm improving again. I managed the longer intervals, 2 x 17½ minutes at 8 kph, without too much trouble. That gave me a total time equal to my PR of 38'58'', and I'm not expecting to get much faster until I can actually run the full distance at pace, but that's starting to feel attainable now. And when I run at the top pace that's properly sustainable is when I'm most likely to get a post-running buzz, which indeed I did. Next mini-goal: 20 minutes continuous at 8 kph.
