While we would like to spend as much time as possible on the bike, the reality is most of our rides are under an hour and a half. During that time dehydration is still a very real possibility, especially if it's hot out where sweat production can easily reach 2 liters aWhile we would like to spend as much time as possible on the bike, the reality is most of our rides are under an hour and a half. During that time dehydration is still a very real possibility, especially if it's hot out where sweat production can easily reach 2 liters an hour. If fluid and electrolyte losses are not replaced, and dehydration occurs, our body temperature rises, our heart rate increases, and we deplete carbohydrate stores quicker and perceive the exercise to be more intense. So we need to keep our electrolytes up but don't necessarily need all the calories that come in many mixes. Thankfully, Science in Sport makes it easy to stay topped off on what we sweat out with the GO Hydro tablets.Each tube contains 20 lightly flavored effervescent tablets that are easy to pop in bottles at the start of the ride, or you can take them with you on longer rides. This allows you to stay better hydrates so you can perform at your best.SiS GO Hydro provides the sodium requirements needed at a specific concentration (30mmol/L) that is scientifically proven to produce superior hydration compared to water alone. It was developed to keep the British Sailing team optimally hydrated at the 2008 Beijing Olympics.The complete product range is developed using a world-class approach to banned substance testing, providing assurance for athletes tested in competitionn hour.
