Dang, Summer is still a month away and it’s already hot. Took a short (hour and 10 minute) ride late this afternoon and came back completely drenched. Based on past experience, hyperthermia ain’t any fun. Time to pace ourselves and hydrate, hydrate, hydrate.
Pedialyte can be your friend. Mix it half an half with water. Bring your regular water also, but have a small little bottle of Pedialyte mixed with water for when you need a quick replenish of electrolytes and other minerals. I was stationed in Louisiana for 4.5 years. When we used to go out for field training I would bring like 10 bottles of that stuff. AMAZING!
I can relate. Riding in FL can be brutal May-Oct. I always take the hydration pack and usually drink about 20 oz. of water with a hydration tab an hour before riding. I have also found it very helpful to begin pre-hydrating 24-48 hours before a longer ride.
