187: Are Your Long Runs the Biggest Risk Factor for Injury?
Sep 12, 2026 · 31m
Summary
The Running Channel Podcast examines a large-scale Aarhus University study of 5,200 runners, challenging the traditional 10% weekly mileage rule. The hosts discuss findings indicating that single-run distance spikes relative to a 30-day baseline are a stronger predictor of injury than total weekly volume. They explore the nuances of acute-to-chronic workload ratios and the importance of deload weeks for recovery. The episode concludes with a lighthearted debate about renaming the half marathon to the "Pekermi" to reflect its unique difficulty.
