Some Work, All Play 301. What To Do Pre-Race, How Metabolism Works For Athletes, Training Races, Colon Health for Runners, and a Great US Half Marathon Update!
50 snips
Mar 10, 2026 Conversations jump from weird uphill treadmill recovery and rapid nervous-system shifts to the constrained total energy expenditure model and why fueling matters. They discuss pre-race warmups, cycling-inspired day-before strategies, training races as real tests, colon health reminders, LA Marathon safety choices, and an update from the US Half Marathon that sparked debate.

Episode notes
Celebration Encourages Future Risk Taking
- Offering finish options and medals at shorter distances can increase participation and reduce fear of failure, which fosters future risk-taking and performance.
- David argues 'participation trophies' can encourage athletes to take more risks rather than soften them.
Do Short Hard Openers Day Before Races
- Do short hard efforts the day before a race to prime neuromuscular and cardiac systems.
- David recommends 4–6x20–30s uphill strides or sport-specific short efforts during the taper to improve race-day feel and cardiac output.
Constrained Energy Model Explains Compensation
- The constrained total energy expenditure model shows physical activity doesn’t raise total daily expenditure linearly; compensations reduce other energy costs.
- When exercise is paired with low energy availability the body downregulates BMR, endocrine and nervous systems, producing famine-like conservation.
