Okay, I'm not 22 anymore. But I'd LOVE to get back into shape to do a long distance ride. BUT when I ride for more than a couple hours now, it takes a VERY long time to feel back to normal. Long time like a couple of days. I am over my optimal weight and can accept I'll never be 165 again. But I really want to get back into longer rides. Is a 2-3 day recovery normal? Do I "need to see a doctor"???? Maybe I just need to ride longer more often than once every couple of weeks?
