Switching from low-drop to high-drop running shoes carries an 86% injury rate if done too quickly. Learn the research-backed 12-week protocol to transition safely, including week-by-week progression, calf strengthening requirements, and biomechanics of the switch.
Applesauce, honey, and bananas can fuel marathons as effectively as gels for most runners. Discover which natural carbs work best on race day, why your stomach tolerates them better, and when gels still matter.
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.
Your arms work harder during running than you realize, counterbalancing leg swing and keeping your torso stable. When you increase training volume or let your form break down under fatigue, arm muscles accumulate damage that triggers soreness peaking 24-72 hours later.
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.
Alex Ostberg, assistant coach at Bowerman Track Club, distills elite training into 4 core variables and explains why absorption, sleep, and consistency matter more than perfectionism. Discover the coaching principles that separate elite runners from the middle of the pack.
Wondering if you should run the day before your marathon? Learn what research shows about shakeout runs, the right duration, and when to rest instead.
Training 6-7 days per week isn’t automatically better than 3-4 days. Your body adapts during recovery, not during the run. Learn the research-backed optimal frequency for your goals and fitness level.
