Welcome!

We’re back on July 8th, 2023 for the 24th year of the SOB trail runs. We call ourselves a trail running festival because we aim for a festival vibe.
Starting with dinner on Friday night, a film festival, and the ever popular camping on the Mountain, we roll right into the races early Saturday morning. We offer a 15K, a 50K, a 50 Miler and a 100K. The 100K is a surprisingly difficult run, with the cut-off at 17 hours.

We encourage registering by March 31st to save some money and to ensure you get into the race. We have a refund policy for all races and a waitlist for the 100K only..
Should you cancel prior to 60 days of the event, 50% of the registration fee (not merchandise) will be returned to you.
Capacities are limited to 150 for 100K, 75 for the 50M, 250 for the 50K, and 350 for the 15k. We've also added special pricing for under 18 year old runners for the 15k. T-Shirt and mug purchase options will not be available after May 1st.
We always offer the ability to drop down to a shorter race the morning of the race should your nerves get the best of you. All ultramarathon distance finishers receive a custom finisher mug, including the 50K!. The SOB is cupless.  We will be providing a collapsible cup to each runner.
Friday night at the Mountain includes dinner (beer and wine available) and the Trails in Motion Film festival. We're hoping to see more of you on Friday night, and camping is always welcome in the Mt. Ashland parking lot. Pre-race breakfast is also included as a meal option. All meals and registration will be in the Mt. Ashland Lodge.
SOB races are awarded UTMB points! 100K is worth 4, 50M worth 3 and the 50K receives 2. The 100K is also a Western States qualifier.

Notice: No transfers or postponements for any reason. If you cannot run for any reason, please know that your entry is going to a good cause as SOB is a non-profit and donates all profits to other worthy non-profit organizations. Unless by prior arrangement with the race directors, the t-shirt and mug must be picked up prior to your race on race day. Any not picked up by the start of your race will be sold to attendees.

100K Course Description

Based on our first three years, this course is not a beginners 100K. Most runners find it challenging. It is a tale of two opposites. The first twenty-five miles are on the traditional SOB 50K course, mostly on the PCT. Care should be taken not to go out too quick on this high elevation, runnable section. Keep in the back of your mind, you still have a long way to go. Prior to Grouse Gap, the course veers north toward the Ashland Watershed, off the PCT and you quickly understand you are no longer on the PCT. You begin the remaining 37 miles with four miles of primitive ridge-top trail, followed by two miles of steep descent, then a lot of lightly used double track (19 miles in total) interspersed with some single track, culminating in a "bruiser of a climb" to the top of Mt. Ashland, followed by a quick descent to the finish at the Lodge awaits. The lower elevations can be hot, and we suggest carrying upwards of two liters of water. During this section you will find four aid stations that will help you recover, rehydrate and fuel.

Total elevation gain is approximately 10,500 ft.

50M Course Description

The first part of the 50M follows the 50K course to the second time through the Willamette Meridian Aid Station.  50M runners will have drop bags available at Siskiyou Gap Aid Station for both directions. Leaving the Willamette Meridian Aid Station you will head north, on the Split Rock Trail. After 4 miles head down the Wagner Glade Trail to the aid station at 2060 (drop bags available), then down Potlicker. Potlicker takes you to Horn Gap Road. Head down the road to the Horn Gap Trail. Go up the Horn Gap Trail to 2060, then out 2060 to Time Warp Trail You will again pass the 2060 aid station where drop bags are available. Up Time Warp (yes, this is a bitch climb) to the top of Mt Ashland, then a quick jaunt to the finish at the Mt. Ashland Lodge.

Total elevation gain is approximately 8,400 ft.

50K Course Description

From the start at the Mt. Ashland Ski Area parking lot, the course heads west to a junction with fire road 40S15 (.4 miles) before intersecting with the Pacific Crest Trail (PCT). The course then heads along the PCT to the Willamette Meridian aid station. From the aid station, the trail climbs to a saddle with views of beautiful Mt. Shasta, the peaks of the Marble Mountain wilderness and Mt. Eddy. The trail continues to another gap and then descends through Long John Saddle to the Siskiyou Gap aid station. If you left a drop bag for delivery, this is where you will find it. The next 3.4 miles will climb on Road 20 (dirt/gravel) to Wrangle Gap, then back on the PCT to Road 20 where you will turn right and proceed to the Jackson Gap aid station, the highest point on the course. Prominent peaks at this gap include Mt. Shasta, Mt. Ashland, Preston Peak (Siskiyou Wilderness), Red Buttes, and Mt. McLoughlin and the Crater Lake rim to the north. Leaving Jackson Gap, the course heads due north on Road 20 for 2.1 miles to Wrangle Gap, meets with the PCT and follows the trail around Big Red Mountain to the Siskiyou Gap aid station (3.4 miles). From Siskiyou Gap, the return is the same route as going out.
Total elevation gain is 4,200 ft.

15K Course Description

From the start at Mt. Ashland Ski parking lot the runners will be on Forest Service road for approximately a mile until reaching the Pacific Crest Trail (PCT). Once on the PCT you'll stay on it, running 2 miles until the first aid station at Grouse Gap. From Grouse Gap the trail becomes a bit steep, but you're only two miles to the turn around at Willamette Meridian. While water will be available at the turn around, the road beckons-- stay on it until you're back at Grouse Gap. From the Grouse Gap aid station, jump on the PCT and return the 3 miles you came to the finish. We'll be waiting for you!
