Chilly weather on Sunday presents unique challenge for Rock 'n' Roll Marathon participants

The Rock ‘n’ Roll Raleigh 5k is scheduled for Saturday from 8 a.m. to noon, and the marathon and half marathon will take place from 7 a.m. to noon on Sunday.

However, many people who are "weekend athletes,” without much experience in events like a marathon, do sign up to test their endurance. For them, there could be a few cold weather issues which can be prevented, he said.

In cold weather, body moisture needs to be controlled, so runners should wear socks and other clothing that "wicks" away moisture to avoid bringing down core body temperature.

Mask advised that participants in the races should bring an extra pair of dry socks and dress in layers, like a vest on top of a shirt, so they can remove some clothing if they begin to feel too warm.

“Some of the natural heat and moisture of your breath is captured in the scarf so the air you breathe out isn't all lost to the air.”

Mask said participants should—and still can—get a full physical exam with an urgent care center before participating in a long distance run, which will help detect high blood pressure, irregular heat beat, or asthma.

In 2014—the inaugural Rock and Roll Marathon—a man died after suffering a heart attack.

Mask urged participants and viewers to look for signs of a heart attack during the event.

“It helps draw attention to how few people are prepared to recognize the warning signs for themselves, or to be ready to perform lifesaving CPR for someone else,” Mask said.
