Ah, needed to remove the underscore from your username, can see your calendar and history of workouts now 
Going back a bit, October, November, it seems like you missed a lot of workouts. Then when you get into December you bail on quite a few such as Wright Peak, Lamarck, Mary Austin. Those latter two are tough workouts and really need some lead up so it’s likely that your missed workouts contributed to that.
This year you’ve been much more consistent and by the looks of things have completed every workout
What build and speciality phases did Plan Builder give you? The latter looks very VO2max intensive for something like Dirty Kanza.
I really wouldn’t worry at this stage about how you compare with others, that will just eat at you. Just work away and train the best you can and on the day do the best you can.
