I did it. I got my Golden Ticket.
It was touch and go1 for a while as to whether or not I'd be able to hobble through the 6.2 trail miles of the Irish Sprint 10K in order to gain entry into the Marine Corps Marathon. But, resting my pulled back for the 2 weeks beforehand--plus going to physcial therapy and getting some good stretching and pulling and electrical stimulation--was enough to make it doable. Slow, . . . . but doable.
I've had two weeks of physical therapy, and at this point, my PT is not really sure what's causing me to repeatedly strain my lower back. Initially, it seemed my left illium was sitting a bit higher than my right.
Now, however, it seems that the muscles around my pelvic bone have loosened up a bit and realignd. (Please note that I really don't understand the magic of physical therapy yet, but I do trust my PT.)
I ran 5 miles on Sunday at a slow pace and my back handled it fairly well. This morning I had another round of PT, and this afternoon I 'm going to run a few miles and then stretch, . . . and stretch, . . . . and stretch.
