Who's going to Silver Moon Race?

Free. You can start with nothing.

Free, and always will be. NavRun makes money from race-day planning for runners who want it, never from this. Ultras change constantly, sometimes the morning of. Always confirm with the race director and the official website before you rely on anything here.

The course

Where it goes multi-loop

Each 2.5-mile lap has 30 ft of climb and 30 ft of descent, between a low point of 307 ft and a high point of 338 ft. To go past 24 hours a runner must reach 85 miles (34 laps) by the 24-hour mark.

The race

What this one is

A lap race on dirt farm roads through orchards and vineyards along the Kings River in Reedley, California, held on the weekend closest to the full moon. It starts at sunset and runs through the night. Runners choose 12K, 20K or 40K, a 6, 12 or 24 hour timed race, or 100 miles in 30 hours, solo or in relay teams, around a 2.5-mile lap with a lap checkpoint and camping on the course.

Pacer rules
Pacers pay a $25 fee, get a pacer bib and full access to the support station and Sunday meals. They can be signed up at registration or later through the contact form. Crew, pacers and spectators turn in a signed waiver at check-in. silvermoonrace.com
Drop bag rules
A designated drop bag area at the lap checkpoint for runners not camping on the course. Volunteers oversee it, and the race is not responsible for missing items. silvermoonrace.com
Cutoff philosophy
Runners must reach 85 miles (34 laps) by the 24-hour point to continue for an additional 6 hours and complete 100 miles within 30 hours. Runners who do not reach 100 miles will not get a DNF, but will have their total miles noted in the results. silvermoonrace.com

Anything else: [email protected]

Ultras change. We will tell you when this one does.

Cutoffs move, races get postponed, lotteries open and close. We read the race's own sources and record where every fact came from. Put your email in and we will send you what changed, and where we read it.

No account, and nothing to cancel.

What happens to your email. Nothing else. I do not sell it, and I will not send you anything except this race changing. One click gets you out.

I keep this catalog because the information is scattered and hard to trust. Telling you when it moves is the same job.
