There's a heat wave coming this weekend. Here's how to deal:
These are the temperatures at which most start to view conditions as less than optimal. The Run SMART Project calculator by Jack Daniels, author of Daniels’ Running Formula, calculates that at 69 degrees, a 40-minute 10K runner can expect to be slowed down by 1.7 percent .
Another adaptation is that you start to sweat earlier in your workout , as your body learns to anticipate the upcoming buildup in core temperature and takes preemptive measures to stave it off. You also begin to sweat more profusely. Your sweat becomes less salty, as the body works to conserve sodium. And your heart rate slows down slightly at any given effort level, allowing the heart to fill more completely between beats, thus having more blood to pump out.
Brett Ely’s triumph reflected something else shown by her husband’s data: Women fare better in heat than men. By Matthew Ely’s charts, the average 2:45 male marathoner would have lost more than 10 minutes to the heat. The most likely explanation is that women, being generally smaller than men, have a higher surface-to-mass ratio—something that allows them to shed heat more efficiently to the environment.
"When the air temperature exceeds 80 degrees and the humidity exceeds 70 percent, performance drops."

Five Two Silicone Oven Mitts & Pot HoldersPreorder your Oven Mitts and Pot Holders today (our Five Two products have been known to sell out fast). Once yours are made, we’ll send them straight to your door. They’ll start shipping on August 9, 2019. When we turned to you to help us brainstorm our new Five Two oven mitts, we never dreamed lightning would strike twice. First, your fantastic ideas (25,000 smart opinions!) paved the way for oven mitts worth writing home about. Second, we realized that for all you do in the kitchen (and beyond), you needed extra reinforcements. That’s where our pot holders come in—dozens of you asked for a snappy set on the side, perfect for quick pickups. So here they are, together in perfect harmony: our oven mitts and pot holders, working side-by-side to handle every task imaginable. We thought through every detail, for two hands-down winners: Magnets & loops for hanging: Each mitt and potholder has magnets so they’ll stick to any magnetic oven, fridge or dishwasher, meaning they’re always in reach. We’ve added handy hanging loops, too. Platinum-grade silicone: Yes, that’s the best you can get—and you’ll feel the difference. Its heat protection is unparalleled (up to 650 degrees) but it’s still super thin and flexible, so you won’t sacrifice movement. No-fuss fabrics: Our mitts and pot holders are made with cotton, so they’re machine-washable, with a low-pile terry liner to keep things comfy. Extra arm protection: 60% of you wanted full-wrist protection, so we made our oven mitts longer to protect your forearms at the stove, oven, grill—basically, anywhere the heat is on. Easy-on, easy-off: As for our pot holders, they’ve got a pocket on the back so you can slip your hand inside (which goes a long way when you need to get a good grip). They do double-duty as trivets, too. Display-worthy design: Lots of mitts and pot holders look the same, but we went the extra mile to create a windowpane design that’ll look great even when they’re off-duty. For a limited time, we're offeri
