          Once I rode 17.5 hours and felt good.  Was up all day at arrival point, slept 12 hours that night.  Other times I've ridden 8 or 10 miles and it was time to go home.  To me the secret is to ride my own ride.  
Walmart, hate to promote them, has a but pad in auto section for about $20, it's jell and works great.  If you are short and do a lot of stop and go you may not want a but pad.  I also suggest waving to kids on bicycles.  Wave to scooter riders, it confuses most of them, especially if you'r on a Harley or Goldwing.
