2023 Wildflower Century

Date: April 29, 2023
Location: Creston, California

The San Luis Obispo Bicycle Club invites you to the annual Wildflower Century on the last Saturday of April. We offer challenging routes on quiet rural roads through vineyards and ranches in Paso Robles Wine Country. The event is limited to 1000 riders and fills quickly 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 Wildflower Century and provide riders FREE event photos.
  • New 30 Mile & Metric Century Routes: Road combinations between Creston and Pozo are used to create two new challenging routes in addition to the traditional 52 mile loop.
  • NO 100 Mile Route: Climate change has decimated the flower bloom along Shell Creek Road and Shell Creek Road itself continues to deteriorate. Therefore, we will not offer a 100 mile route until this situation improves.
  • Start & Finish: Shorter routes allow a more relaxed day with rides beginning at 8:00 AM and ending by 3:00 PM.

This event is not for inexperienced riders or those who have not trained on roads with comparable profiles. All routes take riders through varied environments and include significant climbs – short does not mean easy. Please review the route maps before you register. We want you to be successful and enjoy the day.

The RWGPS files provide both plan and profile views of each route. Once opened, you can move your cursor along the profile to display mileage, elevation and % grade. The RWGPS maps include a link to send routes to a phone or other devices.
