Swamp Rash from Cycling? This Is What’s Actually Happening

What Is “Swamp Rash”?

2 MIN READ 

Let’s get straight to it: if you’re a cyclist (or runner) and you’ve felt the sting of saddle sores, you’re not alone. This painful form of chafing on the buttocks is caused by friction, moisture, and sweat trapped for long periods in tight clothing. 

Some riders turn to petroleum jelly for relief. While it can reduce friction temporarily, it often traps heat and bacteria—making irritation worse and leading to recurring discomfort or infections. 

That’s why choosing the right kind of skin barrier matters. A balm formulated with gentle, breathable ingredients can help soothe irritated skin while letting it breathe, without the heaviness or pore-clogging effects common in many waxy sticks. 

Look for products with non-comedogenic ingredients, like squalane, that protect and hydrate without contributing to breakouts or residue buildup. Applied properly, such a balm forms a comfortable, water-resistant shield that helps prevent further irritation. 

If you’ve struggled to find lasting relief, exploring balms rather than sticks to treat and avoid chafe is a better option.
