Over the weekend, I headed to my local park to run 7 easy-paced miles as part of my training for the upcoming Houston Marathon. Every run is a chance to learn something new, and this one taught me a valuable lesson I wish I had known earlier—the importance of moisture-wicking running gear.
Let me save you from learning it the hard way.
The Wrong Gear on the Right Day
The weather was humid—not unusual for Houston—but nothing I hadn’t run in before. I set out feeling good, but by mile 5, I was sure my hydration pack had sprung a leak. I stopped to check. It was bone dry. Then I realized the back of my shorts was completely soaked—like I had just climbed out of a pool and started running. Not a good sign.
They were new shorts, and while I had worn them for shorter runs, this was their first long test. Around mile 5.5, the front of the shorts started to feel heavy and clingy too. That’s when I knew: my gear was failing me, not the weather.
Why Moisture-Wicking Matters (and What Happens When It Fails)
By mile 6, things got worse. My shoes began to make sloshing sounds. Sweat had trickled down, soaked my socks, and softened the skin on my feet. That’s prime territory for blisters, and I could feel them forming.
And let’s not forget chafing—especially on the inner thighs. If your shorts are saturated, odds are your briefs are too. Without sweat-wicking fabric to pull moisture away from your body, you’re basically stewing in your own sweat.
I powered through the last mile, but I finished frustrated. I wasn’t injured, but I easily could have been if this had been a half marathon or full race.
What I’d Do Differently (and What You Should, Too)
Here’s how you can avoid this rookie mistake:
✅ 1. Invest in Moisture-Wicking Clothes
Look for gear labeled “technical fabric” or made with polyester blends, spandex, or merino wool. These fabrics pull sweat away from your skin to keep you dry. Avoid cotton—it absorbs moisture and holds onto it.
✅ 2. Test Your Gear Before Race Day
Never try anything new on race day. Use long training runs to test every piece of gear—from your socks and shoes to your shorts, tops, and even underwear.
✅ 3. Pack a Small Towel or Sweat Rag
It might seem unnecessary, but having a towel to wipe down mid-run (especially on long runs) can help reduce moisture buildup.
✅ 4. Bring Extra Socks
If you’re doing anything over 6 miles or it’s particularly humid, stash a pair of socks in your pack. Swapping them out mid-run can save your feet.
✅ 5. Body Glide or Anti-Chafe Balm
Products like Body Glide or Vaseline can help protect areas prone to rubbing, especially in humid conditions. Apply before your run and consider reapplying mid-way on longer distances.
Bonus Tip: Pay Attention to Your Shoes
Moisture-wicking socks are great, but your shoes need to breathe too. Choose running shoes with good ventilation and mesh uppers. Wet shoes increase blister risk and add weight to your stride.
Takeaway: Sweat Happens—Be Ready for It
Sweating is part of running, especially in humid areas like Houston. But discomfort, chafing, and blisters don’t have to be. The right moisture-wicking clothes can make or break your long runs. Learn from my slip-and-slosh experience—test your gear early, prepare for the elements, and you’ll enjoy a much smoother (and drier) run.
