Tendons do not respond to training the way muscles do, and most runners' strength programmes don't account for this. Muscles adapt readily to a wide range of stimuli - heavy lifting, bodyweight work, plyometrics, even running itself. Tendons are slower, more particular tissue, and the type of loading that builds tendon resilience most effectively is one that almost nobody programmes deliberately: the isometric hold.For mountain runners, whose sport places extreme and repeated

Continuous glucose monitors were not designed for trail runners. They were designed for people with diabetes, for whom real-time glucose data is a clinical necessity rather than a performance curiosity. But over the last several years, CGMs have migrated aggressively into the endurance sports market, propelled by a wave of commercial interest, athlete testimonials, and a genuinely appealing idea: what if you could see your glucose in real time and use it to make better fuelli

Ask most runners what "aerobic training" means and they'll tell you it means running at a comfortable pace. That's not wrong, but it's incomplete enough to cause real problems in how people structure their training. The aerobic system doesn't operate as a single switch that's either on or off. It operates across a spectrum and as a system, and different points on that spectrum produce different physiological adaptations, recruit different fuel sources, and serve very differen

Three tests that together paint a meaningfully complete picture of where one actually stands as an endurance athlete, and that generate specific, actionable data that no general health panel or 'feel' provides.

A closer look into what running economy is, what it's beneficial for, and how to train for it.

Relying solely on HR data has its limitations. This is where metrics like Intensity Factor (IF) and Training Stress Score (TSS) come in.

Ultrarunners should lift heavy, and lifting heavy weights, as opposed to bodyweight, is the cornerstone of peak ultrarunning performance.

This article delves into the science underpinning the SSC, its impact on running mechanics, and training strategies for maximising its effec
