Not All Fatigue Is The Same
Eccentric fatigue is the assumed villain, except in the legs, where it often isn't. A sprinter, a marathoner and a trail runner break down in three different tissues on three different timelines, and coaching all three the same way fixes none of them.
Same Speed. Different Shapes.
A sprinter and a footballer can hit the same top speed and look nothing alike. New research pulls the two apart, front-side against ground-based, and finds the shape isn't what decides the speed. Here's what actually does, and how to coach it.
Where are the 2021/22 World Athletics U20 Championships Medallists Now?
There’s no doubt that winning a medal at the World Athletics U20 Championships is an incredible achievement. But how often does junior success translate into senior success, and how long can that transition take?
MAS and ASR Calculator
A pace and zone calculator for endurance coaches. One maximal run gives MAS, anaerobic speed reserve, six zones and example sessions with every rep target worked out for the athlete in front of you.
Borrowed From Footballers
A sprint is three efforts, not one, and most of the research was run on footballers. How to train acceleration, top speed and speed endurance across the 100, 200 and 400, with calculators for splits, sled loads and fly targets.
Race Pace and Strategy Planner
Turn a recent race into a projected finish, target splits, and a race-day pacing plan for any distance from a parkrun to an ultra. It reads your course from a GPX and factors terrain, heat, altitude, and your training
The Ulta Gap
The gap between men and women in ultra-running isn't one number. It's about 1% at the median and 22% at the podium, in the same races. This interactive post shows why the answer changes with which runners you count, and how to read any gap figure before you repeat it.
Heart Rate Zones for Runners
Learn how to set more meaningful training zones, compare common calculation methods and understand what the numbers actually mean. This evidence-informed guide helps coaches use heart rate alongside pace, perceived effort and training context to make better decisions.
Train Less, Keep More
More is better" is aimed at the wrong question. Building a quality and keeping one are different jobs: more volume does build more, with diminishing returns, but you can hold what you've earned on about a third of the work, as long as the weight stays heavy.
Why the Standout Junior Often Isn't
The junior who dominates is often just older or bigger, not more talented. How relative age and maturity fool us, and what to do instead.
Lactate isn't the Problem
Blood lactate is gone within an hour of easing off. The soreness doesn't peak until a day or two later. They're two different things on two different clocks, and lactate causes neither, so here's what the burn and the ache actually are, and what genuinely helps.
Periodised to Peak Peformance
At the 2026 Commonwealth Games, athletes who reached 99% of their season best won a medal 57% of the time. Below that line, only 32% did. Here's what separated the medallists, and the target any coach can aim for, at any level or event.
Coaching Female Athletes Webinar with Dr. Rachel Harris
Catch up on the August 2026 Performance Townhall, hosted by Dr. Rachel Harris exploring the health and performance considerations unique to coaching female athletes.
The Reserve Behind the Kick
Two milers can run the same time off completely different engines, one built on a big base, the other on a fast finish. Anaerobic speed reserve is the number that tells them apart, and it flips the training depending on which one you've got.
Same Engine, Different Miler
VO2max gets the attention, but it's rarely what separates milers. The engine, how economically you run, and how much you've got left at the bell each pull their weight, and knowing which one is holding an athlete back is the difference between guessing and coaching.
What Your Tendon Actually Goes Through
Eccentrics for the Achilles, isometrics for the pain: the clinic argues about contraction type as if the tendon can read the label. It can't. A look at what tendons actually respond to, and how to load them.
Eight Hours Is the Floor: Sleep and the Athlete
You can periodise the training, weigh the food and ice the joints, and still leave the biggest recovery tool of the week switched off. What the research says a bad night actually costs an athlete.
From Carbon to Track
Everyone knows a stiffer running blade returns more energy. It has never actually been established. What the evidence can and can't tell a coach.
Mental Adjustment After In-Race Crisis Events
High-performance racing is often decided not only by physiology or tactics, but by how athletes respond to unexpected disruption. In middle- and long-distance track events, in-race crisis moments such as tripping, contact, falls, or sudden loss of rhythm can occur without warning. These incidents create an immediate psychological challenge: the athlete must assess physical status, regulate emotion, restore focus, and make tactical decisions within seconds while the race continues.
Fast Isn’t Enough: Rethinking Pole Vault
Neither step length nor step velocity differed significantly between successful and failed attempts. What did differ was step frequency on the pole-carrying leg, which was significantly higher on the failures.
The athletes were not slower on their unsuccessful attempts. They were travelling at equivalent velocity. What had changed was the manner in which that velocity was produced.
