If you've landed here, there's a reasonable chance you've recently had an MRI, read the report, seen the phrase "full-thickness cartilage loss," and gone looking for what it means for your running. Maybe a clinician told you to stop. Maybe nobody told you anything useful at all. This article is for you. I work as a load-management practitioner — my job is helping athletes train around what their bodies can and can't tolerate. I'm not here to tell you running is harmless, and

TL;DR Pace (min/km or min/mile) and speed (m/s or km/h) describe the same effort from different angles. Treadmills and coaches use speed; most runners think in pace. Use the Running Speed to Pace Converter to instantly translate any distance and time into all four formats — no maths required. If you've ever stared at a speed in km/h and had no idea what that actually feels like to run, you're not alone. Runners think in pace — minutes per kilometre or minutes per mile — but c

Interval running is one of the most effective ways to improve aerobic fitness, running speed, and endurance. One of the most precise methods used by coaches and athletes is Maximum Aerobic Speed (MAS) training. MAS running intervals prescribe training intensities based on an athlete’s individual aerobic capacity. This allows every athlete to train at the correct physiological intensity rather than guessing pace or following generic interval programs. In this guide you’ll lear
