Quad Pain

Quad Pain Going Downhill: Causes and Fixes

Why your quad hurts on descents — eccentric load, mechanics, and how to train it out.

What this pattern usually means

Downhill running multiplies eccentric load on quads, knees, and the patellar tendon. Pain only on descents usually points to strength or mechanics, not structural damage.

What to do today

Walk descents for 1-2 weeks while you rebuild capacity
Add eccentric quad work (slow tempo squats, step-downs)
Increase cadence 5-10% on downhills
Avoid braking — lean slightly forward, shorter steps

When to worry

• Pain now showing up on flats too
• Catching or locking sensation
• Sharp pain you have to limp from

Common causes of quad pain

Eccentric overload (downhills)
Quad strain
DOMS from new stimulus
Patellar tendon referral

Could it be one of these injuries?

Patellar Tendonitis (Jumper's Knee)

Patellar tendinopathy — 'jumper's knee' — is degeneration of the patellar tendon just below the kneecap. Common in jumpers and sprinters; in distance runners it usually shows up after spikes in hill work or speed.
