Heavy sweaters—athletes losing more than 1.5 liters of sweat per hour—need 800–1,500 mg sodium per liter of sports drink to match losses and prevent performance decline. Most mainstream drinks deliver only 300–500 mg/L, making high-sodium options or pickle juice necessary for high-sweat sessions.
In two weeks, the world’s fastest-growing fitness race crowns its champions. The 2026 PUMA Hyrox World Championships run June 18–21 at Strawberry Arena in Stockholm, closing out a season that saw hundreds of thousands of everyday athletes sprint, push, pull, lunge, and row their way through sold-out arenas on five continents. The format never changes: … Read more
Sodium is the primary electrolyte endurance athletes need during training—typically 500-700mg per hour for efforts over 90 minutes. Magnesium and potassium support muscle function and recovery but are lost in far smaller amounts through sweat.
AVP Tour League Week 2 in Aspen kicks off June 6–7, 2026. Pro beach players lose up to 2 L of sweat per hour on 140°F sand. Here’s the sodium-first hydration playbook that gets you to the bracket — from night-before loading to between-match recovery.
Electrolyte timing depends on exercise duration and sweat rate. For sessions under 60 minutes, post-workout replenishment is sufficient. Endurance athletes need pre-loading 2-3 hours before and continuous intake during exercise, while HIIT athletes benefit most from immediate post-session replacement.
A 100-mile race is a sodium-and-water problem that lasts long enough for small mistakes to compound. Here is the Western States 100 hydration playbook — pre-race load, high country, canyon heat, river crossing, night miles, and post-race recovery — and how to steal the strategy for your own ultra.
Endurance athletes need sodium (300-700 mg/hr), potassium (100-200 mg/hr), magnesium (20-50 mg/hr), and chloride to maintain fluid balance, muscle contraction, and nerve signaling. Sweat rate, duration, and sport intensity determine your exact replacement protocol.
Baseball looks like a slow sport. Pitchers stand around between batters, hitters take their cuts and walk back to the dugout, and innings can drag past 30 minutes. But the calendar tells a different story: a Major League team plays 162 regular-season games, the 2026 College World Series runs June 12–22 in Omaha (the 79th … Read more
Calculating your sweat rate is simple: weigh yourself nude before and after a one-hour training session at race intensity, track fluid intake during that hour, and use the formula (pre-weight – post-weight + fluid consumed) to determine hourly fluid loss in ounces or milliliters.
Inside the four-window hydration playbook that gets NHL players through Stanley Cup hockey — and how beer-league skaters and youth-tournament parents can borrow it.
