The Growler route is completely full for 2022. Additional entries into this route are not being accepted at this time.

The Growler route features King Ridge and The Geysers. It is essentially EVERYTHING. It is formidable. You must be prepared!

When we reimagined Levi's GranFondo, we couldn't imagine it without the retention of the Growler's signature level of difficulty. After tackling King Ridge, you then take on a completely new set of roads that travel like the spine of a dragon's backbone high above the surrounding hills of Sonoma County. Your return to the gently rolling valley floor comes at the price of taking on two more long, steep climbs along Stewards Point Road. It's not nearly over. The Geysers, and another 3,000' of difficult climbing awaits long after you've already amassed nearly ten thousand feet of elevation over the course of the previous 90 miles.

Qualifying Time:

In order to participate in the Growler in the future (2023 and beyond), you must qualify!

The Growler route is timed from the moment we start until we reach the highest point along the course on Geysers road at mile 109.5. If it is your objective to participate in either the Gran or Growler in 2023 (because for 2022 they are full), you must qualify this year. We require this because the Gran and Growler routes are very challenging, and we must vet your ability to confront either, even though you're already signed up for it this year. In order to qualify to retain your option to register for the Growler in 2023, you must make it to the finish line at the Festival in Windsor by 5:30 pm (10 hours).

Time Cut:

If you do not reach the Cloverdale aid station at mile 91 before 2:30 pm, you will not be permitted to continue to take on the Geysers and must be downgraded to the Gran route. But this gives you 7 hours to reach this location and represents a 13 MPH average speed. If you don't make the cut, you still have 3 more hours to reach the festival to achieve a successful qualifying time to have the option of trying it again in 2023.

Four (4) full aid stations and two (2) water stops:
The Growler route features four aid stations at miles 45, 55 (self serve water only), 83 (self serve water only), 91, 109.5 and 122. This means your first full aid station does not come until mile 45 after you've done a significant amount of climbing. Please take this moment to consider your fitness level, and what you'll bring with you to make it to this first aid station on King Ridge. Aid stations will feature water, electrolyte, fresh fruit, snack items and other foods that are safely prepared and/or individually packaged to prevent the spread of COVID-19.
