Has anyone experienced what I call leg tiredness, which is this. I rode decent ride up and down hills 20 miles at 17.4 MPH now it's the second day after and I have absolutely NO energy to do anything, my legs hurt. They just ache, they feel good if they have pressure applied to the muscle. EX: if I reach down and squeeze my calf and put pressure on the muscle and roll my hands around, it makes my calf feel good. Is it that I am getting sick? or is this something that others have experienced? It may because I don't get any good sleep or what? any opinions are appreciated. I used to ride every day 30 miles a day, but took off cause of an injury, now I want to get back to every day, but why do my legs hurt? Thanks to all who reply, it's appreciated.
