I ride when I don't feel like it. I use the 20 min. rule. If after 20 min. I still don't feel like ridding I turn around & head back home.
Unless I have at least 7 hrs of sleep I do not ride. I am too tired. I have a sleep apnea, I use a CPAP to sleep at night. So now I have no reason to not get enough sleep. I need a minimum of 7 hrs to fully function the next day. I make sure I get at least 7 hrs of sleep a night.
As far as I'm concerned there is no reason or excuse good enough for anyone to not get the minimum of 7 to 9 hrs of recommended sleep & rest. I know, I've been there before I was tested & diagnosed. I had all kinds of excuses, except what I really thought it was & admitting I had a problem. It got so bad I could spend 12 hours in bed & still be exhausted & tired. I went to my dr. & now I'm glad I did.
