Hydration can make or break a long run, but there isn't a universal formula that works for everyone. Kramer Ammons shares how he tests everything from sweat rate and hydration timing to where runners carry their water, explaining why the most efficient solution isn't always the most obvious. The conversation explores handheld bottles, hydration belts, vests, bladders, and why convenience often matters just as much as laboratory efficiency. Don and Scott add decades of racing experience, emphasizing that successful runners solve problems early instead of waiting until dehydration, stomach issues, or fatigue force them to slow down. The discussion also covers pre-hydration, electrolytes, carb drinks, aid station strategy, and how listening to your body is often more valuable than blindly following generic hydration guidelines. The biggest takeaway is that great hydration isn't about copying someone else's plan. It's about experimenting until you discover what consistently works for you.
