Yowser, am I suffering today!!! I started with 40 miles cycling on Tuesday and 5 hours of skating, and then did 20 miles riding and 3 hours of skating each day on Weds, Thurs, and yesterday. My muscles are aching and shivery, I feel zoned out and have done nothing but stay collapsed on the couch all day and have had a 2 hour afternoon nap. I've also got extreme hunger and thirst. It's not flu though, more like extreme distressing pain from overexercise. I'm sure I used to be able to do much more than this last summer. Maybe it's just too early in the season to be fit enough?
