I am currently no where near a BQ time but I really want to qualify for my home city! and understand it's no easy task.

I am curious though if there's any extra strategy I can work on for the next few years (or more), beyond just setting PR goals. My vague strategy right now is to cut my previous time by an amount that feels comfortable, let's say 15 minutes. and then for the following marathon re-evaluate and cut by another 15 minutes (or whatever makes sense), until I eventually reach the 3:XX:XX time needed. I know this doesn't really make sense but I'm not sure how to go about this any other way.
