Aquila, where are you riding? What type of riding? (mountain, road, hard, easy?)

For me, a liter an hour is nothing when I ride in the mountains or the desert. But here on the east coast, a liter will last a few hours. Everyone is different.

I had this gross feeling actually yesterday. The way I get rid of mine? Simple sugars. Jellybeans, hard candy, anything to get your blood sugar up in a hurry. Energy drinks do the same but over the years I found that when I feel really bad (ie totally depleted) I need sugar. And I can't stand candy any other time (except chocolate) so I got plenty of easter candy still to burn through.

If you can, see a sports medicine person. This was one of the things they told me about when I went to see them for some other things. The last thing I would of eaten was jellybeans. So whatever works...
