I guess overtraining is a possibility. I took a week off to go to NYC recently and when I got back my first few workouts seemed easier. I get between 8 and 9 hours of sleep a night so it just doesn't seem like I should be so tired. I also have year round allergies but I don't know what I'm allergic too. They aren't very bad...just enough to keep me congested most of the time. My doc has never suggested finding out what the cause is...I guess because they aren't severe. I don't want to give up the boot camp 'cause it's actually helping me lose weight. WooHoo! 8 pounds so far! And I sure don't want to give up cycling. One of my cycling friends tells me, "You're supposed to be tired!" but I just can't see being totally wiped out for a full day...that just seems a bit much.
