Expectations versus reality without a running coach.
When training, racing and or completing so much goes into the coaching structure. If you do not implement a periodised training plan allowing for the development of a larger aerobic base, speed and strength, flexibility etc, you will not get faster, or stronger. As a runner, you will eventually get to a point where you will stagnate. You will, however, feel the benefits if you allow for a slow and consistent progressive overload and a variant of training stimuli. The process is stimuli and progressive overload with adequate recovery and sufficient time for adaptation. This will result in small changes, leading to big achievable goals.
