SIOUX CITY | When it comes to running, Jim Ewoldt says the colder the weather the better.
"There is nothing more exhilarating than a dead-of-winter run," said the owner of Peak Performance Fitness Gear at Southern Square. "It's also a good conversation starter because people tell me I'm nuts for running in the cold."
Ewoldt said he's been doing it for more than 25 years.
"As long as you keep moving, it doesn't seem cold at all," he said.
While prepping for a cold weather run, Ewoldt said you should plan for weather that's 20 degrees warmer than it actually is.
"For instance, if it's 20 degrees outside, dress as if it's 40 degrees," he said. "It may be cold at the beginning, but you'll warm up in no time."
Ewoldt also recommends dressing in layers, starting with a base layer of a shirt that's lightweight, comfortable and, more importantly, fast-wicking.

"The best base layers will wick away your sweat as your run heats up," he said. "Your core cools faster than any other part of your body. You must protect your core."
On top of the base, Ewoldt said runners should invest in an insulated piece of clothing that will ensure moisture management while allowing for the right amount of stretch.
"You really don't want any clothing that that will restrict upper body movement," he said, showing off a wide selection of stretch jackets and hoodies.
A third layer -- or a shell -- is a recommended way to finish your wintertime running wear. Ewoldt suggests a zipped outer layer that will allow you to maintain a comfortable body temperature while blocking frigid winds.
He said jackets containing an interior thermal-conductive pattern will allow you to retain your own body heat.
"It will keep you warmer longer," Ewoldt said.
But what can runners do to remain safe during the short days of winter?
"Runners get into trouble when they're not visible to drivers, cyclists and other runners," Ewoldt said. "To stay safe, runners should outfit themselves with reflective gear like armbands, snapbands and a clip-on strobe light."
Even better than that are jackets, hats and pants that are equipped with their own reflective material.
Looking at the more modern running wear, Ewoldt said he's amazed at how far technology has come in wicking away moisture. He's also amused at how fashionable clothes have become.
"When I started running, everything was cotton and not very breathable," he said. "You can wear some of the new stuff on a run or when you're out shopping for groceries."
Still, Ewoldt encourages fellow runners to keep warm and safe.
"I prefer running in the winter," he said, "but everybody has their own comfort zone.
"There's nothing quite like a run in the winter."
