5 Ways to Prevent Chafing on Long Runs

If you've ever finished a long run and discovered raw, red patches where your shorts, shirt, or sports bra used to feel fine — you already know. Chafing doesn't just hurt. It changes how you run. You shorten your stride. You skip the next session. You start dreading the distance instead of chasing it.

The good news: chafing is almost entirely preventable. Here are the five things that actually work.

1. Choose seamless, moisture-wicking gear

Cotton holds sweat against your skin and turns every seam into sandpaper. Switch to technical fabrics designed to move moisture away from the body, and look for flat or bonded seams in high-friction zones (inner thighs, underarms, nipples, sports bra band).

2. Identify your hot spots before they flare up

Everyone chafes in slightly different places. Inner thighs and underarms are the classics, but feet, waistband, neckline, and bra straps all show up depending on your build, gait, and gear. Pay attention after your next long run and map yours — that's where prevention goes.

3. Apply protection before the run, not after

This is the biggest mistake we see. Most runners only reach for an anti-chafe product after they already feel the burn. By then, the skin is irritated and the run is half-over. Protection works when it's on your skin before the friction starts.

That's exactly what Dry Goods is built for: one quick spray to your hot spots before you head out, and the 360° applicator coats evenly without the mess of sticks or balms.

4. Hydrate — but watch the salt

Dehydrated skin is more fragile, and dried salt from heavy sweat acts like fine grit between your skin and your clothes. Drink consistently through the run, and rinse off salt-crusted gear before the next session.

5. Recover the skin, not just the muscles

If a hot spot does flare up, treat it like any other injury: clean it, let it breathe, and don't put it back into the same friction the next day without protection. A 24-hour recovery window plus protected reintroduction beats five days of limping through workouts.

The bottom line: chafing is a friction problem, and friction problems are solved before they start. Build the 10-second pre-run habit, and you stop thinking about your skin and start thinking about your pace again.
