Rest is paramount for us active folks at 50+. Depends on how active you are as to how much rest is appropriate. You owe it to yourself to rejuvenate your body and mind with some scattered breaks throughout the year (may not have to be as long as 2 wks). If you are very active (which daily riding is) you will add years to your future of exercising if you allow the body to rest, recover, repair. Think of it as investing in your body... saving something for the future as you age more. Be safe!
