Not everyone is ready to run for 6-hours or more, but they love to run in beautiful locations, so we have a 10K option to allow runners to come out and get a taste of the Silver Moon Race experience and enjoy the beauty of running around the CASS vineyard at sunset for some breathtaking views.

The beauty of a fixed-time format is it removes that distance barrier and allows you to focus on pure running. Doing 2-mile laps is easy, you keep on running until the time runs out or until you get tired.

You can take a break to rest or even nap between laps, the choice is yours. Yet, even when tired, your mind keeps telling you that you can do one more lap, then another, and another, before you know it, you've run more miles than ever before and you feel awesome for hitting a new milestone.

Remember, you will get out of this exactly what you put into it. Run solo or team relay.

Running 100-miles is the biggest milestone for many ultra runners. It is not an easy task, taking determination, persistence, patience, and grit to push on through. The Silver Moon Race is perfect for runners attempting their first 100-miles or for seasoned runners to improve their pacing, training, and endurance.

Some runners will hit 100-miles within 24-hours, others will need more time. Runners must reach at least 85-miles by 24-hours to be allowed to continue for up to 6-hours to reach 100-miles within 30-hours. Run solo or team relay.





Run the race of your choice solo. Pacers are allowed the course and you can have a crew at the race festival to provide support at each lap check-in.

Team Relay


Run the 6/12/24-hour or 100-mile race in a 4-person team relay. Take turns doing laps or sets of laps equally to get in as many laps as possible as a team.


While the race is chip timed to track runners, total laps, and time for final results after the race is complete, there will be leaderboards set up for 6, 12, 24-hour, and 100-mile runners to visually track their laps.

As a runner completes each lap they will stop at the leaderboards, find their name, and mark off the lap they just completed, then continue on the next lap. Repeating for each lap. This is required, only the runner is allowed to mark off their completed lap.

Sharpies will be provided, however, we do recommend runners bring their own color sharpie or marker to mark their laps. Everyone having their own color makes it easier to visually see your row of progress.
