Great information from all....thank you. The camelback was almost drained....about two inches remaining when I completed my ride...it was one half ice cubes/one half water when I started...warm water at the end. I consumed about 2/3rds of a small package of "Sport Beans", but that was probably not enough since the packaging said to have a full package before the ride and every 30 minutes while riding. I had a decent breakfast.

Suggestions about sodium, calcium, magnesium and potassium (didn't have any bananas in the house), and a drink mix, along with more training are much appreciated.

This group is an inspiration...thanks to all for your advice!
