Why This Matters
Cardiorespiratory fitness is associated with long-term health. Muscle mass and functional strength (calisthenics) protect against sarcopenia — the age-related muscle loss that accelerates frailty. These metrics aren't vanity; they're longevity biomarkers.
New running personal record · October 12, 2026
9:06 for 1.5 miles
Estimated VO₂ max: 56.6 mL/kg/min. That is 24 seconds faster than my January 26 run of 9:30.
Self-reported run. Formula: 3.5 + 483 ÷ 9.10 minutes = 56.58, rounded to 56.6. Pace: 6:04 per mile. A timed-run estimate is not a laboratory VO₂ max measurement.

About VO2 Max Testing
VO2 max measures the maximum rate of oxygen consumption during exercise — the gold standard for cardiorespiratory fitness. I estimate mine using the 1.5-mile run test (Cooper test variant).
Formula:
VO2 max = 3.5 + 483 / time_in_minutes
