Whats the most effective way to pre-hydrate for a cold-weather bike race when water intake can lead to frozen water bottles and a bloated stomach, while electrolyte-rich drinks can crystallize and become useless, and is it even worth risking dehydration to avoid the discomfort of mid-race pee breaks in sub-freezing temps? Should we just accept that were gonna be a little parched and hope that adrenaline will carry us through, or are there some secret strategies that the pros use to stay hydrated without turning their bottles into ice sculptures?
