What force pulls me near the ocean for solo road rides... Maybe gravity. Could be childhood memories. Most certainly it's the views of rocky beaches and the sound and smells of the crashing waves. But also it's the salty towns along the shore that a cyclist can weave the back roads and off the beat places that you normally wouldn't go because it's just out of the way.
The ocean serves as the perfect guide for a cycling route, you can get lost but the premise is simple...just keep the ocean to one side and pedal for hours. Although I did get turned about face for a moment or two while navigating northward toward home. No worries, found a hill to ride up and took a look around and got back on course.
