This route is the 600k version of the San Diego 3 Loops series. The first 200k loop will have the most climbing as you ride toward the north inland portions of San Diego County. Riding on El Camino Real, you'll roll your way through the rural neighborhoods of Bonsall and Fallbrook riding on quiet country roads until you reach Rainbow for a quick refreshment. You'll make your way south on Old Hwy 395 to reach West Lilac Rd, where you'll continue east through more farmlands and sparcely populated parts of San Diego County into Valley Center, stopping at Bates Nut Farm. Reaching the highest elevation on the route when you turn toward Lake Wohlford, you make your descent to Escondido, passing Lake Hodges on your ride to Poway, reintering the suburban landscape of San Diego. Eventually you'll make your way back to the coast at UCSD and returning to Encinitas along the coast to complete the first loop.

The next 200k loop is an easy coastal cruise from Encinitas to Coronado, taking advantage of the Bayshore Bikeway in the South Bay and Silver Strand, returning inland on Genessee Ave, 56 bike path to Camino Del Sur and some short rollers through Fairbanks Ranch and Rancho Santa Fe back to Encinitas. The highest elevation on this route is the top of Torrey Pines. But the inland leg will be a roller coaster ride when you reach Linda Vista. The loop is predominantly coastal urban, so there are lights to contend with, but you will pass by all the notable beach communities along the way.

The final 200k loop will take you north into Orange County as I ran out of flat roads in San Diego County. From Encinitas, you'll return to Coast Hwy and make your way into Carlsbad and Oceanside. You will need to jump on I-5 in order to pass Camp Pendleton. If you have a valid pass base to enter the Marine Corps base, you are welcome to take Vandergrift Blvd and then Stuart Mesa to Las Pulgas, but expect bonus miles and added elevation gain vs the I-5 passage. When you reach Dana Point, you'll jump on the San Juan Creek river trail and start your trek inland through the various "Lagunas" communities until to reach Irvine. Your return leg will take you on Laguna Canyon Rd to Laguna Beach. Once you see the Pacific Ocean, you'll ride on  the coastal rollers back to Dana Point, descending down Cove Rd to reach the scenic harbor before retracing your outbound route back to Encinitas for the finish.

The overnight stop will be at the Days Inn. You may choose the Days Inn or the Best Western right up the hill with more stately amenities for your overnight lodging.If you are checked in before the start and stay until the finish, you can leave your overnight bag in your room or you can drop off your overnight bag with the organizer for pick up after the first or second loop. You are responsible for booking your own overnight lodging. If you would like a roommate to share the cost, an email distribution list will be created to support your arrangements. The floor of the ride HQ room may be made available based on space allowance for randonneurs who want to rough it. Keep in mind, serving riders arriving and leaving is priority over your need for quiet space. 

To the start by car: If you are booking a room at the Days Inn or Best Western for the overnight control, you may park at their lots as hotel guests. If not a guest, the manager will allow you to park for a $5-$10 fee (still being finalized). If you want to park for free, Parking is available on the Encinitas Station Park and Ride on Vulcan Ave just down the street from the start. Parking is not available at the Moonlight Plaza across the street. There is a 2-hour limit and you will bear the risk of your car being towed if you decide to park there. 

To the start by train: If you are travelling to the start by train the day before, you can take Amtrak to Oceanside or Solana Beach station and then jump on the San Diego Coaster train to Encinitas Station.
