Sun 8/8 - AM 2:15 very easy plus 24 minutes in Walden

Not sure if I'd be able to run at all today after yesterday's unexpected blowup with the left adductor. Woke up not feeling quite as bad as when I went to bed but still nothing so great. Gave it a try in hopes of things loosening up over time. Moving very gingerly and extremely, mind-numbingly slow at first. Range of motion in left leg microscopically small during the first 35-40 minutes of superslow plodding, gradually the leg did loosen up just a bit with less pain and stiffness. Pace increased somewhat but still quite slow. Kept it there for the rest of the run. Could have run for many more hours at this speed, relaxing if very boring. The time spent in the water felt the best once again, able to move the leg through the full range of motion. Spent nearly an hour stretching after the run. Still at a loss to understand how the left side came to be aggravated so badly by yesterday's race, the answer has to be some kind of previous injury/aggravation to the area while I was in Colorado. Avoiding a recurrence of what happened yesterday is another matter entirely, the current stretching/strengthening protocol apparently isn't sufficient which is troubling.
