Evidence-based training, fueling, recovery, race strategy, and the mental side of going long.

START WITH YOUR QUESTION
01 / RESEARCH PULSE
Three new laboratory studies examine personal thresholds, dry versus humid heat, and women’s equipment combinations. A clearly labelled 7 October cycling trial adds catch-up fueling evidence. Useful findings remain bounded by who was studied, what was measured and how long the test lasted.
Read the complete research briefNo protocol change. Interesting findings are not automatically a reason to change your training.
Within-participant laboratory comparison
Supports the existing distinction between a useful group marker and a validated personal training-zone boundary.
Primary source (opens in a new tab)Crossover heat-acclimation laboratory study
Supports retaining humidity and event context when interpreting heat research; the study is not an eight-day prescription for runners.
Primary source (opens in a new tab)Four-condition within-runner laboratory comparison
Supports considering the equipment combination and the outcome being measured; lower acceleration alone does not prove injury protection.
Primary source (opens in a new tab)Source verification and evidence confidence are different. Some archive sources remain unresolved. Check the source audit
02 / THE PRACTICAL PROTOCOL
Use the Action Plan for your training week and the days before, during and after your event. Keep scope, safety and sources beside each action.

THE ORIGIN COLLECTION
ORIGIN STORY · EDITORIAL
Miles of Meaning began with a practical question: how can research become useful in an actual training week? The original protocols, tools and research history remain the foundation.

A DIFFERENT PERSPECTIVE
Training, physiology, fueling, recovery, psychology and race execution belong in the same conversation. Understanding their connections helps us ask better questions about going long.
