2023 Lighthouse Century

Date: September 30, 2023
Location: Morro Bay, California

The San Luis Obispo Bicycle Club invites you to the Lighthouse Century on the last Saturday of September. We offer relatively flat 75 mile and Metric Century (65 mile) routes along Highway 1 and a more difficult Century traveling east toward Paso Robles before returning to the coast. Experience scenic vistas and cool ocean breezes. Limited to 1000 riders, the event will likely fill before registration closes so register early to ensure your place in this classic ride.


What's New

  • Event Photos: We have partnered with Captivating Sports Photos to document the Lighthouse Century and make photos available to our riders.
  • Century Route: Our classic century route climbs up Old Creek Road to Hghway 46 and east to a rest stop at the Donati Winery before returning to the coast. This is a challenging route for strong experienced riders.
  • Relatively Flat Routes: The 65 and 75 mile routes along Highway 1 are well suited to beginning riders and those that want to focus on riding along the coast.

Lighthouse Routes

The RWGPS files which can be opened by everyone provide both plan and profile views of each route. Once opened, if you move your cursor along the profile, it will show the mileage, elevation and % grade at that point. The RWGPS maps include a link to send routes to a phone or other devices.

Routes RWGPS Cue Sheet
Century: 95 miles, 5300 ft. Century Century
75 Mile: 2300 ft. 75 Mile 75 Mile
65 Mile - Metric Century: 2000 ft. 65 Mile 65 Mile

A Brief Description

The 65 and 75 mile routes follow historic Highway 1 from Morro Bay north through Cambria and San Simeon and on past the Elephant Seals and Piedras Blancas Lighthouse depending on which route you choose. Given the out and back nature of these routes, you can adjust the length of your ride to suit the day, weather and your enjoyment – there is always the option to turn around.

The Century route climbs up Old Creek and then turns east on Highway 46 to Donati Winery before returning west on Highway 46 to join Highway 1. The route has over 4000 feet of climbing in the first 28 miles followed by a long, fast and exposed descent. Once on Highway 1, the Century heads north with the other routes to the turnaround above Piedras Blancas Lighthouse.

Note: Both the 75 and 100 mile routes pass by the Piedras Blancas Lighthouse.

Happy Bike riders along coast.
