Lighthouse Flat Century

After leaving Cuesta College, you first travel south toward San Luis Obispo before looping back north along Los Osos Valley Road - a favorite of local riders. You'll then rejoin the Metric riders just south of Morro Bay and ride with them to Cambria.
You'll continue north past San Simeon, Hearst Castle and the lighthouse before reaching your turn around at Piedras Blancas. Along the way, you have some great views of coastal hills, the coast, and (possibly) some sea lions.
You'll then return to Cambria for lunch before riding with the Metric riders along highway 1 all the way back to Cuesta College.
When you return to the BBQ, you will have added about 98 miles and 3,500-feet of climbing to your credits
