I used to ride that Ormond loop or a variation of it when I lived in Port Orange, FL. I started off Dunlawton & Nova Road, crossed the Bridge to the Peninsula, rode all the way down to Ponce Inlet on the road closest to the Halifax River, then thru the park. At the ocean, that areas sandy beaches are hard enough to drive cars and ride a road bike on at low tide. From there I rode North all the way to Granada (SR 40), then rode to John Anderson, back North thru the Tomoka/Ormond loop and came back South thru the Mainland side and Beach Street, taking that all the way South to Port Orange again. I'd have to map the miles out, but I made a day of it and took my time.

Now adays, I ride from North Miami Beach to South Beach, FL, it's 15 miles down, so a 30 mile round trip and I've gotten that to 40 minutes each direction. I ride around South Beach with friends, so that works out to 35 miles or so for those rides. My other ride is NMB to Dania Beach pier, that's only 10-12 miles each diraction, but I get to ride thru Hollywood, FL's boardwalk and it's a nice Venice Beach, CA like atmosphere with a park with a paved trail.

The South Beach ride has traffic & road construction and can be dangerous. The Dania Beach ride is more enjoyable. As for the Port Orange to Ponce Inlet to Ormond Loop that was a great ride, but I haven't done that since 1987.

I also lived in Jacksonville for about 4 years, wasn't into cycling then but reflecting back, missed opportunities there, not only Jax/Ponte Vedra to St Augustine, but rides from Jax Beach to Fernandina Beach/Amelia Island. Also could've rode St Augustine to Matanzas Inlet or Marineland, FL ? Just a lot of bikeable routes for a road bike or Touring bike.

I still have the bike that I did the Ormond loop too, it's the 86 Fuji Allegro. Love that bike and it's still immaculate for it's age and mileage.
