Chino Grinder course

What is the Chino Grinder?​

The Chino Grinder is a 115 mile-long bicycling endurance challenge on the Perkinsville Road, consisting of a 35 miles of pavement and 80 miles of gravel traversing from from Chino Valley, Arizona (12 miles north of Prescott) to White Horse Lake near Williams and back to Chino Valley.

Who can participate in the Chino Grinder?

The Chino Grinder is an event for the experienced and well-trained endurance bicyclist. Although not technical, this is a challenging course with 9700 feet of climbing. If you have not completed a century ride in the past you should consider signing up for either the 25 mile, 44 mile or 62 mile course options the first year to be able to gauge your level of fitness. This will be an annual event so you will have the opportunity to try the 115 miles the next year.

What kind of bike will I need?

A gravel specific bike is your best choice. A cyclocross bike would be a good choice, tough enough for the gravel and light for when you hit the pavement. A mountain bike would be the most comfortable but you will pay a price for the weight, especially on the 22 mile climb from the Verde River up to Williams.

TIRES: We recommend nothing narrower than 32mm, most riders run a 38mm or larger.

Can you ride a road bike on this course? You could, but we don’t recommend it. Brice Smith rode his road bike to 8th overall the first year we held the event. The next time he did it he was on a gravel bike. If you’re set on giving it a go we suggest doing some course recon at some point on the first 30 miles (mostly dirt and gravel roads) so you know what you’re getting yourself into.

What is the course like?

The course is comprised of two county maintained roads. It is an out and back course 115 miles in length. The gravel section varies between smooth hardpack and some areas of washboard, there a number of wash crossings but generally speaking they do not slow you down.

Will the course be marked?

Yes. This website contains a detailed map that you should checkout before the event. Major crossroads will be signed. Aid Stations will be located near the Verde River Bridge (22 miles from start, also the 44 mile turnaround) and at White Horse Lake near Williams (57.5 miles, also the turnaround). Aid Stations will be stocked with water and refreshments. A SAG vehicle will follow the last rider on the course.

Am I allowed to receive any outside assistance during the event?

No, outside support at any point other than official checkpoints will result in disqualification. Riders may assist other riders by any means and at any time.

What equipment should I carry on the Chino Grinder?

Outside support (except from other riders) is prohibited other than at official check points located at the the aid stations. You should plan on being as self-reliant as possible. Here are some suggested items to carry when riding the Chino Grinder.

May I have a support crew follow me along the route?

NO. Support crews are not allowed on course. We will provide a SAG vehicle that will provide assistance if a mechanical issue causes you to abandon the event. Additional vehicles on the course will compromise the event for the participants, especially the dirt section. If a support crew is found to be on course, that rider will be immediately disqualified from the event.
