My knee hurts after long runs. How should I change my training?
Marathon-distance running can cause measurable changes in knee kinematics (increased varus rotation, anterior translation, and flexion) after long runs, which may relate to knee strain. 1
Higher training volumes and appropriate long runs are generally associated with better running economy durability, but excessive increases without adaptation can raise injury risk. 2 3
Injury risk in long-distance runners is associated with previous injury history, training volume, and shoe replacement frequency; moderate training volumes (40-60 km/week) and regular shoe replacement (8-11 months) were protective in one study. 4
Reduced training volume has been associated with fewer running-related injuries in youth runners during COVID-19 restrictions, suggesting training load is linked to injury frequency. 5
Strength/plyometric or gradual walk-to-run training programs can alter running kinematics (e.g., more extended leg during swing) similarly, which may influence loading patterns relevant to knee stress. 6
What we can't tell you
- The evidence does not directly address how to modify training specifically for knee pain after long runs.
- No card specifies safe progression rates, rest intervals, or specific exercises for knee pain relief.
