I agree with the sports drink.
Another thing I use for long bike rides are gel pack. GU makes one that I like better than Power Bar. It's basically a tablespoon or so of gell that gives you ~100 or so grams of carbs. I eat one every 30-45 minutes on my road bike if I'm riding over an hour. Might be good for your situation in the am when you need energy but nothing much on yor stomach. You need to drink water with it. Also, you can purchase these in boxes of 24 from places like
www.Nashbar.com or any other biking or probably running sites.
Cytomax is a great sports drink, to me better than Gaitoraide, etc. It really help with the lactic acid build up that helps soreness later.
