EARLY & CONTEXTUAL EVIDENCE
Downhill loading, eccentric adaptation and why foot strike stays individual
Four publications from 19–25 September were appraised. They support existing cautious downhill exposure and technique rules, but do not justify a new 100K prescription.
Read the complete research briefWhat changes?
No protocol change. Interesting findings are not automatically a reason to change your training.
- 01
SYSTEMATIC REVIEW AND EXPLORATORY META-ANALYSIS
Repeated eccentric exposure reduces later damage, but the neural mechanism remains uncertain
Supporting evidence only. Keep gradual downhill exposure and the 24–48-hour soreness/control check; do not infer a precise protective dose or a settled neural mechanism.

ACUTE BIOMECHANICS STUDY
A non-rearfoot strike did not reduce downhill impact loading
Supports the existing form rule: do not impose a universal foot strike. On descents, prioritize control, quiet short steps and symptom-free testing instead of forcing forefoot contact.

CROSS-SECTIONAL OBSERVATIONAL STUDY
Running-economy correlates are not a body-composition prescription
No weight-loss target or body-composition intervention follows. Continue to train economy and aerobic capacity while protecting adequate energy availability.

03 / FROM THE FIELD
THE ORIGIN COLLECTION
ORIGIN STORY · EDITORIAL
A 100K question.
A longer view.
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.
Read the origin storyExperience has a place here. It stays clearly separate from scientific evidence.
A DIFFERENT PERSPECTIVE
Same paths.
A wider view.
Training, physiology, fueling, recovery, psychology and race execution belong in the same conversation. Understanding their connections helps us ask better questions about going long.
