To be fair to myself, I'm old and not really in running shape [yet] and the fastest mile I've ever run was like 9:38, seven or eight years ago.
I wasn't built for speed.
It occurred to me last night that if I can't run a sub-10-minute mile, I'm not going to complete a 5K in the half-hour time slot during the final week of the training program. Which is fine, I guess. I'm making good progress and am a whole lot faster than I was the first week!
