Tue 9/18 - PM 70 minutes in Brookline

Ran relatively easy, although the pace picked up in fits and starts after the 40 minute mark. Started from Cleveland Circle and went off into the wilds of South Brookline, avoided getting hopelessly lost as I have in the past in this area. Spent all day at work expecting knee soreness to be a problem, it didn't show up until the 30 minute mark. While manageable, it was sore the rest of the way and particularly noticeable on hills. Still at a loss to understand what exactly I did to bring this about, only that it had something to do with Sunday's effort in flats. I'm thinking the root cause lies with the IT band tightening up. In addition to working on that area I've gone to the old standby of doing straight leg raises. Continued cool and breezy conditions today, third day in a row that felt very autumnal.
