School is out but there's no break for some student athletes who are staying busy training this summer. As temperatures heat up, keeping those athletes safe is a big concern.
Out at Fresno's Woodward Park, Robert Breuer and his friends are training for the upcoming track and field season at their school.
With about an hour and half of running planned, the runners say they've got to ease into their workout.
"To prepare to run we do a little mile warm up, get used to the heat, get acclimated," Breuer says.
With the warming weather, don't let the heat be a shock to your system.
Even for the athletic types, exercising in weather a person isn't used to can wear on his or her body, says Aaron Samansky, owner at the Sierra Running Company.
"Just make sure you ease into it. Don't do anything that is out of your routine. If you're a 5 a.m. runner and you missed your run that day, and it's going to be over 100 degrees, you might have trouble running at 4 p.m.," Samansky says.
Around the park, a group of children are keeping active biking the hills on the course.
Lauren Bayless says she's keeping a close watch on her 5-year-old son as he may not recognize the signs of heat stress as easily.
"Just watching the color on his face. When he takes his helmet off, he's extremely sweaty, so just continuing keeping the water in him," Bayless says.
Staying hydrated and taking plenty of breaks in the shade--it's common sense. But when you're head is in the game, your eye may not be on the thermometer.
"And if you don't feel good, quit. That's the main idea. You don't want to just burn yourself out," Breuer says. "That'll get you out a week of training, and you'll be that much more behind."
Around local schools, student athletes are practicing their sport. Doug Semmen, athletic director at Fresno Unified School District says part of keeping safe is knowing when temperatures are simply too dangerous.
"Our protocol is when the temperature reaches 105, we cancel everything," Semmen says.
Below that, Semmen says scheduling practices is left to the coach's discretion, but the district encourages practices during the early morning or evening hours.
"We tell our coaches to keep an eye on kids and to be sensitive to heat issues and to symptoms of possible heat illness," Semmen says.
