Right yes I've ridden hundreds before just going in to make a fun day hopefully weather cooperate can't control that. I am 52 so yea 20 years younger but only been riding for about 12 years in the world of road biking that can be a beginner.I'm not as fast as I used to be. Age and less than consistent riding has slowed me.That said, I fully expect to get back to "hustling" bike sometime in the future. I was always known to be a very good climber for a big guy, and I was absolutely fearless on descents.
From the pace of your 53 miler today, I think you are more than ready for a century. A 100 miler too, not a 100K. Have you ever ridden one before?
Just on the off chance that you can and want to make a trip to Cali, I think Marin would be ideal. The Marin Century has always been my favorite century of all, and I've ridden over 50 centuries. The roads in Marin County are perfect, the scenery breathtaking (no pun intended), and the Marin crowd has always been a fast and racey group. That combination is right up my alley.
In reality, I'm good for the 100K at best, and even then that's going to be a challenge. I'm not in good shape right now and at age 72 I can't be foolish. The only thing I have going me at the moment is that I've have a lot power and endurance, plus the mental tenacity to keep riding even when I'm used up. "Riding wounded" as I describe it.
In my decades of riding centuries, double centuries, brevets, and PAC Tour (2x, 1,000 miles per week!), I've only had one DNF. That was in Colorado riding a 200K brevet (at the time a relatively easy distance for me). But this Cali boy rode unprepared for the weather and got caught in a freaking snow storm halfway through. My barely clothed, half frozen, ginger body was as red as a freshly cooked lobster! I was on the verge of hypothermia.
At any rate, @#18FAN, the time on your cyclometer tells me you're ready to rock. I think you'd ride Marin very well. Keep me in the loop.

I generally do it for cardio fitness but it's something about the mental part people don't understand generally with people that just lift. I lift about every other day that I don't ride and ideally for me two days rest of the legs not total rest I may lift the day before is best for endurance rides for me.
I look up to many people and learn read and study alot on endurance rides my bike shop owner is the best endurance race rider in the country at 58 winning Race Across America in 9 days averaging 320 miles a day I respect him to no end and is so easy to learn from his discipline is relentless attitude but the most kind and humble guy you'll ever talk to.
Again I'm joining in maybe for little motivation for ya and maybe sounds like good time for the both of us heck maybe we could get others to join in whatever millage the can do.
