Your VO2 max measures how much oxygen your body can use during hard effort. Here’s what the numbers actually mean, how runners compare by age, and whether testing is worth it.

Most runners can improve by 5 to 15 percent over one year of consistent training. But how much faster you actually get depends on your experience level, age, and training approach. Here’s what research says about realistic pace improvement and how to maximize your gains in 12 months.
Learn the aerobic fitness level required for running doubles, why training frequency triggers mitochondrial adaptation, and how to structure doubles safely without overtraining.
Most runners measure marathon readiness by how many workouts they completed. But the real question is whether the training was calibrated to the right fitness level from the start. Coach Jeff shares the 2-signal framework he uses to tell athletes whether they’re on track.
