The course

Where it goes · 11 aid stations

Course line from the race's own GPX. Source file. Recorded 2026.

Starting near the top of the Siskiyous at Mt. Ashland Lodge, the 100K loops around the mountain to a steep descent into the Ashland Creek Watershed, tours many of Ashland's most popular trails, then climbs back to the high country and the Pacific Crest Trail. It runs the last 25 miles of the 50K course, the out and back along the Siskiyou Crest, and ends with a final climb to the top of Mt. Ashland and a steep descent to the finish at the Lodge. The direction is the opposite of past years.

Trekking poles are permitted.

We read every one of these and we write back. Every fact here carries the source it came from, and the way a wrong one gets fixed is a person checking it against what you tell us.

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.
