You should need to pee at the start of every ride, and remember, the water you drink today will help you the most tomorrow,,,~~

I get up and drink 35 to 40 ounces within the first hour, with coffee, and juice and what ever else.
This big water load up front helps trick your body Into thinking there Is plenty of water so It will use and not conserve water. You like many probably spend most of your life dehydrated...
I continue to drink 8 to 12 ounces of water per hour all through my workout, ride, yard work, day job, whatever..

Now for the secret:

RE-Hydration is often neglected after the ride.....
Use this chart before and AFTER a ride, re-use the chart even on the next day....
I do not start a ride Unless I am a 1 or a 2
I often end rides a 3 or 4 and I Immediately RE-Hydrate back to a 1 ..

Got tired of cramps I did,
,
,Yes I know how to eat the right way....
