Episode notes
Choose Discipline Not Motivation For Consistency
- Do choose discipline over ephemeral motivation by committing to the run even when you don't feel like it.
- Stephen emphasizes showing up after work or when tired rather than waiting for inspiration to maintain progress.
Weight Loss Can Raise Numbers But Reduce Sustained Power
- Losing weight can raise relative VO2 values but may reduce absolute power and the ability to sustain high liters/min VO2.
- Scullion uses Christian Blumenfeld's example: lighter can equal weaker if muscle capacity drops.
Split Your Week Into Base Ceiling And Extension Work
- Do structure a marathon week into easy base, intervals to raise your ceiling (VO2) and extension sessions to increase duration at race fitness.
- Scullion suggests ~20–30% high-intensity work (VO2/threshold) and the rest split between easy and extension runs.
