Notes
After two days of GI problems, I was finally able to finish a planned run. And what a run it was! Started off at an easy feeling 7:35-40, and kept it at this pace for about 40 minutes or so. Around 40 minutes in I started dropping 45-60 second surges to about mile pace, and then easing back to a gentler pace, which also got faster as time went on. At the end of the run I was cruising along, still very relaxed and in control, at 6:45 pace.
Interesting note: the 6:45 last mile didn't feel any different than the 7:35 first mile. In fact, if someone asked me to guess the time of my last mile I would have said 7:15-20 at the fastest.
