I went for a solo ride Friday night. Kept it moving and felt good. I’ve seen a jump in my fitness the last few weeks. I charged a few segments and climbed a bit more than usual but nothing crazy. I felt fine after the ride but tossed and turned during the night with soreness. I had to be up early for an appointment. All day I’ve the aches but not normal sore muscles, more like a have a touch of the flu. I may have been a bit dehydrated before the ride? This has happened a few times in the last few years. Anyone else have this happen?
