Your Future Abilities
Most runners overestimate how much they can improve in the short term while underestimating how much they can improve in the long term. Skip the allure of hacks and short-cuts. There are no singularly magical workouts. Focus on consistency and comfortably adaptable progression. While you may have a base-building period early in your calendar year, appreciate that the entire year, and even next year is building the base for the runner you can be in three years. The runner you are today is a product of your attention to those fundamental principles of consistency and adaptable progression from years past, not just weeks or months past.
