Meadow Vista Park

1101 Meadow Vista Rd. Meadow Vista, CA

8 Miles north of Auburn

Start time: 9:00 am

Check-in will open at 7:30 am

We are encouraging people to come out and ride in their favorite flannel/plaid outfits. Of course, we will not judge you if you want to come out in your spandex or Hawaiian shirts.

The recommended steed for this event is a gravel/adventure/cyclocross bike with big tubeless tires. Tire specifics depend on conditions and weather, but you'll want something you're comfortable riding on a dirt/gravel descent with manageable rolling resistance for the pavement. All bikes are welcome and doable, so just come along and run whatchu brung! Just remember to bring tubes and some essential tools because there is a chance you may have an incident out on the course. If you choose to ride a road bike, you should probably start with some fresh rubber and try to fit some big ones on there.

40-50% of this ride is on gravel/dirt/broken pavement, with the rest on good pavement.

We are offering two route options this year:

- The normal route:42miles 6k ft of elevation (est. ride time: 3-4 hours)

- The longer route:60miles 8k ft of elevation (est. ride time: 4-6 hours)

Choose wisely. Both are challenging routes!

Early registration is strongly encouraged! We will be capping the event at 200 riders.

Some notes about the day.


The course will have aid stations with water, drink mix, and light snacks. 

Please come prepared to change a flat!

We are on mixed terrain, and the probability that you will flat on course is high. Ensure your equipment is ready (good rubber, newer brake pads, thoroughly checked drive train). We recommend a tubeless set-up from our favorite bike shop, Kinetic Cycles in Sacramento.

Post ride:

Lunch will be provided.

Tacos! Yes, the same ones from prior years :)
