One of the most important
things to remember while
cycling, as with any other
physical activity, is to keep
well hydrated. Your body
relies on water to keep it
going and with the proper
hydration, you will perform
better. A water bottle on
your bicycle frame will do
the job, but hydration
systems in the form of a
backpack (such a Camelbak)
makes even more sense.
Water is more easily
accessible and people
tend to drink more because
it is convenient. They
also keep the water cooler
and you can carry two or
three litres.
