Why masters runners (40+) Get Runner's Knee

Tracking issues at the kneecap, usually driven by weak glutes, quad imbalance, or training spikes.

In masters runners (40+) specifically, the risk is amplified by lifetime-load training with longer recovery requirements. Specific to 40+ runners whose recovery and tissue tolerance shift with age.

• Stiffness after sitting

When to Stop and Get Checked

These signs mean you're past self-care territory — see a sports medicine provider.

• Pain that stops you mid-run
• Swelling
• Pain on every step

What to Do This Week

If you caught it early, here's the self-care protocol most masters runners (40+) respond to.

• Reduce mileage by 30-50%
• Quad and glute strength daily (split squats, bridges)

• Ice after sessions

Prevention: Stop the Cycle

• Glute and quad strength 2-3x/week
• Cap mileage jumps at 10%
