All in all, I see good signs. Very good signs with the training and I’d gladly take soreness and aches over anything ending with “itis”. I think you’ve set yourself up well for a very solid run.
That’s a good way to look at it. Think positive, hope for the best, and then realize that you should control what you can and deal as best as you can with what you can’t control. You’re not the only one hoping for an October that is more moderate than the summer months have been, though.
Most people never will be huge mileage runners and I don’t think anyone should expect that of anyone else. Whether we expect that of ourselves is another concern but it is a personal concern. What you have shown this summer is that you are a consistent moderate volume runner who covers all his bases and doesn’t let distractions get in the way. That kind of consistent and balanced training at the level you have been at for the past half year will serve you well.
