Spinning is a new functionality in Enduraid. It is important to mention, what the app also indicates, that the system prepares the training nutrition plan for spinning with a high heat-humidity coefficient because there is no wind so the salt and water replacement obligation is much higher. At this stage of the year, a triathlete's, but even a runner's training plan may include a lot of spinning, which means that the focus should be on salt and water replacement if it comes to refreshment. There is no compromise in hydration which doesn't mean only water replacement but minerals as well.
The race/training is your business, leave fueling with Enduraid!
