Wow- first post and workout since Monday. Tuesday and Wednesday I was wiped out and rested, but was weird tired today still. Others in the group mentioned this, so I'm writing it off as a seasonal change thing. Definitely not age-related. And now, for a nap...
A.M.- Mobility work, targeted drills, KB circuit.
Ran 5+ miles with the pack, including 6 hard 1k intervals.
