In the spirit of things not going according to plan...
Since the three runs last week went well enough, I decided to try extended the mile treadmill test with 1/2 mile of easy running to 1-1/2.
The next three days my hip hurt. What's worse, it hurt in a place that I'm pretty sure wasn't a place that indicated a strained or sore IT Band or anything else muscular. This time it was right in the outside of the joint. The place I'd expect to have something seriously wrong with a (on Monday) 63 year old hip with a couple dozen thousand miles on it. Not that I ever expected my hip to go out enough to end my running career. Nor do I know enough to say that that's what happened.
Anyway, what it means for now is that I've taken the rest of this week off and am questioning whether to try again before the end of January.
For now, I'm watching plenty of movies and shows on Disney+ and Prime Video, plus football on the weekends. OK, I'd be doing that regardless of my running status.
But it does suck not to run.
