Electrolytes aside, you need to hydrate more. Gatorade is really more sugar than sodium anymore, but I do think that higher-sodium sports drinks are a good idea (Sodium and water tend to hang out together, so if you take in sodium, water will follow).
Good luck, and drink plenty of water!

You're probably right. I ride with a heartrate monitor and when I made my last 10 minute stop to rest at about 43 miles into the ride, my heartrate stayed above 125 bpm. Most of the ride was at about 145 bpm. I am almost 48 years old, type 2 diabetic, about 40 pounds overweight (I have lost 28 this year) and am just getting into better cycling shape. Hey I'm trying hard though!!!
