Hi,

I'm new to biking and have been building up my distance over the past two months. I've been biking about 3 times a week and increase my distance by a few miles each week.

It seems anytime I bike 15 miles or more (max so far has been 20), about a hour after the ride I have no energy. A wave of exhaustion comes over me and I end up having to take a nap and it takes me several hours to recover.

If I ride in the morning, I eat a bowl of cereal, toast, juice and some fruit. During the ride I drink water mixed with Gatorade. I also bring along a energy bar to have during the ride if I feel hungry. After the ride I will have some water and eat a meal. What am I doing wrong? I really like biking and feel ok when riding to go farther, but I'm worried that I'm not getting the right amount of something to feel so exhausted when I'm done.

Any suggestions or ideas would be great! Thanks in advance
