This Tuesday I am starting my 3 days on Ragbrai. It's a week long event but I am going to do half of it.. then do the whole thing next year. Ragbrai is basically where you bike across the state of Iowa between 50 and 80 miles per day. I will be doing days of 53, 51, and 79 miles. I was curious if any of you had experience with such rides and what you do during to help stay hydrated, stay loose, and not cramp up. I've been training since May for this and I am in fine shape for it... so that's not an issue. I just was curious if any of you had any good advice from experience.
