Fri 1/15 - PM 70 minutes incl. 6x100

45 minute warmup, over to the river and back via corridor park. Drills and then 6x100 with 100 jog. Overdid it with the faster stuff. Worried about LG/quad tendinitis all day at work, that felt fine during the run but first the right and then the left hip flexor were bothersome on the strides. The left side strain from two weeks ago reared its ugly head again, still tweaked. Not that it should be a surprise, although the degree to which the core is weak and susceptible to aggravation is mind-boggling. Can't imagine how I ever was able to run at speed for any sustained length of time. Slow to steady running not a problem, of course. Change agonizingly slow in coming.
