Heat Doesn't Wait For The Unfit
Chicago 2007 hit 25°C and 30.7% of the field didn't finish. Heat acclimation fixes most of that in one to two weeks, and you don't need a chamber - a normal run and a hot bath will do it.
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.
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.
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.
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.
