and coaches generally agree that there are three ways to improve running performance: you can increase your maximum oxygen uptake, or VO2max, which measures the greatest volume of oxygen that can be dispatched to your muscles during exercise; you can extend
oxygen-delivery machines who know their VO2 max and use the impressive numbers to bolster their confidence. Armstrong knows his VO2 max, too. His long-time friend, confidante, and coach, Chris Carmichael, has had his star pupil tested on several occasions
of running not mileage totals, not your marathon PB, and certainly not the percentage of VO2 max you can maintain when running at lactate-threshold pace while holding your breath on a treadmill set at a six-per-cent-incline in a hypoxic tent. These Zen
