For those of you in the Northern Hemisphere, the days and indeed nights have been a steady parade of 100 degree highs. The heat has been record-breaking for much of the country. For cyclists, this means extra attention must be paid during rides to avoid dehydration and the accompanying muscle cramps.
As a younger and perhaps stupider rider, I was able to get by with plain old water in my bottles. Water was an economical beverage choice for a college student on the edge of penury in addition to being "readymade" and easily found in a variety of taps and spigots. As I have aged and found myself with a little more disposable income, I have grown to enjoy putting things into my formerly "plain" water to keep my muscles from locking up like a pair of brakes on interstate 26. Although powders work adequately, I have found the ease of hydration tablets to be more my speed.
A hydration supplement that keeps you feeling normal during extreme heat is a plus, but one that gives you a little something extra is an invaluable bonus. While tablets might not meet the needs of serious racer types, they're excellent for casual or training riders to prepare bottles quickly but with the knowledge that everything their muscles need for a ride will be provided, including large amounts of sodium which will leave lovely, decorative white stains on your jersey. Fashionistas take warning!
