Fingers Crossed......

Went for a "taper run" this morning on my usual 5k hill circuit.  After about 2 miles I felt a distinct "twinge" behind my left knee...   uh oh!    Didn't want to mess anything-up before the OBX half this weekend, so I walked for a bit to be safe.   Don't think it was a big deal - ran the last half mile at about 8:30 pace and didn't feel it.   Fingers crossed!
