Running 33:52 [3] 6.48 km (5:14 / km)
shoes: 200809 NB Absorb EX 12
Gentle run at exactly the pace I planned. Breathing was 4/4 throughout, route was Elm St - Cambridge st loop. I raced a street cleaner running down Beacon St. Temperature was -5 C with clear skies and 16 kph winds. I wore two shirts, long shorts, a sweatshirt, gloves and a hat. For interested parties, I ran at 12:30 AM.
Discomfort in my left achilles was moderately noticeable, increasing at the end. I would never describe what I felt today as pain, but I am displeased with my state. Also, my right hamstring was tight and bothersome during my run. I'm hopeful that these are correlated, and that the root cause is as simple as nutrition.
In any case, I attempted some brief strides midway through my run without significantly adverse effect. I will be ginger in my running this week, but barring some significant change in my condition, I will run the Ran-it Granite (with a gentler approach to the sprints than is my usual fare).
