The race

What this one is

Three trail races named after the headwaters of the Sacramento River, held in the Klamath Mountains west of Mount Shasta City, California: a 52k and a 34k on single-track and dirt forest roads, and a 10k on the Lake Siskiyou Trail. Mt. Shasta and Mt. Eddy are the backdrop. Every runner gets a post-race meal, a t-shirt and a finisher's medal.

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.
