Sat 12/25 - PM 70 minutes incl. 8k threshold run

Tiger Drive to Longfellow loop, twice around. Didn't bother timing, tried instead to gauge effort and keep it controlled. Felt pretty good once I got going although the left hammy was stiff and felt weak at the very start of the run. Less problematicat the end of the faster running than it was Thursday but I wasn't on a track and wasn't going as fast. A few icy stretches on the loop but mostly clear. Cold temps but thankfully no wind to speak of.
