How Do I Keep Up With My Hydration?

i have a hard time keeping up my fluid and take on longer runs and hikes. Would a sweat analysis be beneficial? And if yes, where can i get one done, and how much do they cost? If you author is hiking, this is likely not something you're focusing on. But when we look atike, the power ra power weight ratio component, til like endurance racing, if you're not getting a reduction in performance by losing, say, one to two % of your body weight from fluid loss, you are reducing your weight,. You are not losing muscle. Your not losing his power, your power generating capacity by that reduction.
