Wildflower Century

Date: April 27, 2019 (New)
Location: Creston, California

The San Luis Obispo Bicycle Club invites you to the 48th Wildflower Century as it returns to the last weekend of April. We offer five routes on quiet rural roads through vineyards and ranches in Paso Robles Wine Country. Register now to ensure your place in this classic ride.


What's New

  • New Date: The 2019 Wildflower returns to the last Saturday in April!
  • New Route: A 52 mile route that starts at 10:00 AM and follows the second loop of the century ride. The second loop roads through Pozo are some of our favorites and provide a challenging and beautiful ride that is an excellent alternative to our great Metric Century.
  • New Paving: Highway 58, Highway 41 and O'Donovan Road are repaved and provide additional miles of smooth riding.
  • RFID Satellite Tracking: The tracking system will record the flow of riders to enhance their support and offer two “Personal Best” challenges. The challenges will include a 1 mile sprint and a 1.6 mile hill climb (KOM). The Century, 75 and 64 mile routes will include both the sprint and hill climb (KOM) challenges. The 45 mile route will include the sprint but not the hill climb (KOM) challenge. The new 52 mile route will include the hill climb (KOM) but not the sprint challenge.
  • E-Bikes Welcome: Routes are e-bike friendly – they follow two loops that each start and end in Creston. E-Bike rules and information are provided on the FAQ Answers webpage.

All routes except the Half Century (52 mile) begin by climbing up Highway 41 followed by two fantastic downhill runs on the way to Shandon. After Shandon there are 7 miles of rough pavement out Shell Creek Road that we refer to as our cobble stone section. The remaining section of Shell Creek is smooth and includes the 1 mile sprint challenge and ends with a spectacular display of flowers if mother nature is kind to us.

Open a route's RWGPS file from the list below on a desktop or laptop computer to see its profile showing the route's distribution of climbs and descents – a profile's vertical dimension is exaggerated. If you move your cursor over the profile, it will show the mileage, elevation and slope percentage at each point along the route – slopes less than 3% are gentle, slopes above 6% are work.

All routes except the 45 end with a 1.6 mile climb up Highway 229 that is the hill climb challenge (KOM) followed by a four mile descent along a shaded road and ending with a flat three mile run by vineyards and ranches into Creston and the post-ride BBQ.
