Riding heads south towards the Oceanside Light House and Harbor, passing the infamous pier, to to Carlsbad riding along side the ocean, then turns inland at Encinitas. Heading east, Ramona grade, is your first climb, five miles, of about 4-5%, in quiet morning hours, avoiding traffic on Ramona grade.
It then connects to Old Julian (back) Rd., a six mile moderate climb, and on over to Santa Ysabel for Apple Pie. There is one more seven mile 4-6% mountain type climb to the summit, in old the historic country western town of Julian, where you may pass the one-horse buggy walking along the one country block.
Next, comes an awesome 17 mile descent down Banner Grade into the beautiful California Borrego desert on a flat road with two/ half mile chocolate-chip type hills, then flats with short fun dips and a usual tailwind, usually,that eventually lead to the left –fork turn towards Borrego Springs.
At this turn, there is a two mile 4-6% climb, with an eight mile descent that overlooks another view of the Borrego desert, leading you to lunch at the Park in the center of the road, Lunch. (Your last signal light was at 50.7 in Ramona, and your next signal will not be until 155.5, Valley Center).From lunch, continue around the Park circle heading west with a three mile warm-up before you begin your climb out, on Montezuma grade.
This eleven mile mountain climb is your major climb of the ride, with temperatures cooler if you left very early, to warm, but not as hot as they could be, and. with the winds on the last 5-6 miles picking up gradually. I highly recommend you leave as early as you can, ascending this mtn. earlier in the day, because the winds may kick up. There is a water stop half way up. From the Summit at Ranchita, a ten mile sweeping, downhill is your payback, leading to Lake Henshaw, RS 4. From here, you'll ride a flat twenty mile stretch along the base of Palomar Mountain, then descend five miles to Valley Center Road, RS 6.
The next climb, Valley Center Rd., is 3.5 miles of a 4% grade, which is the last major climb. That said, along Lilac Road, are mild 1-3% grade back road, short, gentle rollies leading to a descent for 10 miles, to Bonsol, Rest Stop 6. From Bonsol to the ocean is virtually flat for 13 miles. The last seven miles are on the bike path, ending at the ocean, a mile from the Finish.
