Runner on the San Gabriel Peak Trail, working up toward Mt. Disappointment. Mt. Wilson is the peak with the towers. West Fork is in the canyon on the left.
Even in Southern California the weather can be a little fickle. Just two weeks ago, heat had been one of my concerns for the No Name 50K. During that race the temperature reached into the mid-80s. Heat definitely wasn’t an issue for this morning’s race on Mt. Wilson. Several days out one computer model had forecast sleet and a temperature of 32°F! Instead, at the start of the race runners were treated to a spectacular sunrise and a temperature of around 40°F.
After a five year hiatus, the Angeles National Forest (Mt. Disappointment) Trail Race is back. Started in 2005 by R.D. Gary Hilliard, this was the 14th running of the highly regarded event. Today we ran the 25K course, but in 2025 a 25K and 50K will be offered.

Whatever the distance, a hallmark of any ANFTR/Mt. Disappointment courses is that it starts and ends on top of Mt. Wilson (5739′). While not particularly high, the altitude is just high enough to take the edge off a runner’s performance. Many a runner has underestimated the difficulty of the final five-mile climb from West Fork to the top of Mt. Wilson — especially on a hot day in July or August.
My race went well, and I left enough in the tank to enjoy the climb up the Kenyon Devore Trail!
Thank you Gary and Pam for your dedication, passion, and the hours and hours of work required to put on a quality event! And thanks also to all the volunteers, runners, and others that support the race.
Ahead, the lights of two runners turned this way and that, and behind me more headlamps danced up the canyon. The moon was high in the sky and nearly full. I took advantage of a smooth stretch of fire road, and turned off my headlamp to enjoy running in the surreal light.
Getting ready to check-in runners at the No Name 50K/15K
I was in Cheeseboro Canyon and a mile or so into the 2024 No Name 50K. Along with several other runners, I had opted for the early start. Partly because there’s something special about running in the hours before dawn, but also because strong Santa Ana winds were forecast, and I wasn’t sure how hot and windy it was going to get. So far, so good. The only wind was a sometimes cool, sometimes warm, down-canyon breeze.
Usually, when I run Cheeseboro Canyon, it’s from the Victory Trailhead at Ahmanson, and I run down the canyon. It was good to be running up the canyon for a change. The Cheeseboro Canyon Trail is a combination of fire road and single track that gains about 500′ over the 4+ miles to the Sheep Corral Trail junction. There are several very short, steep, rocky sections, but most of the trail is straightforward and enjoyable. Because of all the rain the past two years, the trail near Sulfur Springs was a bit muddy. Running by headlamp, I managed to step in the muckiest of the mud.
Dawn from the Sheep Corral Trail.
From the top of Cheeseboro, it’s about a mile over to Palo Comado Fire Road on a well-used, up-and-down single track. Just before Palo Camado, I stopped at an overlook to take in the view to the east. San Gabriel Peak and Mt. Wilson were silhouetted in the distance, and a few orange-red clouds preceded the sun.
Once on Palo Comado Fire Road, it took about 15 minutes to get up to China Flat. The timing was perfect — the warm light of the new sun highlighting Simi Peak and the greens and golds of the oak grasslands.
Downhill on Albertson Fire Road to Lang Ranch.
The aid station at Albertson Mtwy Fire Road marked the beginning of a 3-mile downhill to Lang Ranch. I put out of mind that we would be coming back up this hill and just enjoyed the descent.
Following a quick stop at the Lang Ranch aid station, I retraced my steps on Albertson Fire Road back to the Alapay/Lang Ranch Ridge Trail and the start of a scenic 3.5-mile keyhole loop. This memorable segment sets the tone from the start, gaining about 500′ in a mile. The route is a variation of the popular “Lang Ranch Loop,” and the support from the hikers on the trail was much appreciated. So was the encouragement from the awesome group of local runners (in the title photo) — each of the three times I passed them. I still hear their cowbell!
After returning to the Lang Ranch Aid Station, I started up Albertson Fire Road a second time. The volunteer at the Alapay/Lang Ranch Ridge Trail checked my bib number, and I began the long climb back to China Flat.

After doing the steep climbs on the Lang Ranch loop, the grade on Albertson didn’t seem so bad. Plus, the weather was cooperating. We were on the second day of a Santa Ana wind event, and I had envisioned running into a 20 mph headwind here. Other than a couple strong gusts, the wind was more of a cooling breeze.
The runner passing me confirmed that the Albertson climb was made for poles — if only I had them. I’d done Albertson on a training run and debated using them for the race. Poles are helpful in a lot of ways, but more efficient uphill propulsion is probably the most important.
After a false summit or two, I eventually reached the aid station at the top of the climb. The smiling volunteers asked me if I needed anything. I told them I was good to go and continued down into China Flat. I could relax for a while. It would be mostly downhill until the aid station in Palo Comado Canyon — about 3.5 miles away.

Running down Palo Comado from China Flat was a bit like the run down Albertson, except it was 20 degrees warmer. With the low humidity, I reminded myself to stay hydrated and not pound the downhill. The Cheeseboro Ridge section of the course was a few miles ahead, and the last thing I needed was crampy legs.
At the Palo Comado aid station, I grabbed a peanut butter sandwich and headed up the hill. Like the climbs at Lang Ranch, the hill was steep but relatively short. As I started the descent into Cheeseboro Canyon, I looked across to the power lines on Cheeseboro Ridge. There were runners over there, and I wondered how they were doing. I would find out soon enough.
At the Cheeseboro aid station, I filled my Camelbak to the brim, put some chips in a baggie to eat on the run, and started up the fire road toward Cheeseboro Ridge.
The Cheeseboro Ridge segment of the course follows an SCE powerline service road for about three miles, gaining more than 700′ along the way. On a hot day, it can be very hot, and on a windy day, very windy. There is zero shade. The Cheeseboro Remote Weather Station is passed about a mile up the service road.
Superb running in Cheeseboro Canyon.
Keeping in mind that the station measures the temperature inside a white, ventilated instrument housing several feet off the ground, the Cheeseboro RAWS midday temp was around 78degF and the wind was 16 mph out of the ENE, gusting to 29 mph. On the fire road, the in-the-sun temp was at least in the mid-80s but didn’t feel too bad.
I was glad to get to the high point of the ridge at the rocky overlook. There were still a couple of small hills to go, but from the viewpoint, it was going to be mostly downhill to the finish.
Many thanks to SoCal Trail, the volunteers, photographers, runners, and everyone involved for a great race!
In my experience, there are several things you can count on when running in a KHRaces event — a challenging, well-marked course, well-placed and supplied aid stations with helpful volunteers, reliable timing, good food at the finish line, and plenty of portable toilets at the start. That was certainly the case for the 2024 Malibu Canyon Trail Races in Point Mugu State Park.
The 100K, 50M, 50K, and 30K courses used many of the same trails as those in the Ray Miller Trail Races — including the hallmark start and finish on the Ray Miller Trail. The courses were out and back — which means you get to say hi to everyone in your race and be astonished by the speed of the faster runners.
Cloudy, Cool and Humid Weather
Into the clouds on the Ray Miller Trail.
Ten days before the race computer weather models were predicting the possibility of hot weather, but as race day approached the marine layer prevailed, and on June 8th the weather — though a little humid — was cool and cloudy throughout the day. Here are temps and other data on race day from an SCE weather station near the 50K turnaround near the Danielson Multi-Use area.
A few hours into the race, some runners looked like they had been in a rainstorm. For once, I was well-hydrated at the end of a race!
Water Crossings and Wildflowers
The wettest back-to-back rain years (measured at Los Angeles) in 100+ years had a tangible effect on the race, resulting in numerous get-your-feet-wet creek crossings and stunning displays of wildflowers.
Some runners were determined to keep their shoes dry, but most got their feet wet at least a couple of times. Having run with wet shoes most of the Winter, I surrendered to having wet socks and shoes early in the race. Just about every time my socks and shoes started to feel somewhat dry, another crossing would soak them.
I lost count of the stream crossings on the 50K course, but using Google Earth imagery from May 2023, it looks like there were around 12 (times two) crossings in Sycamore Canyon, plus a few more in Wood Canyon.
In many ways, volunteers make the race, assisting and encouraging runners in any way they can.
Phenomenal Performances
With the cool weather, there were some very fast times. Scott Traer crushed the 50M in 7:07:43, and Osvaldo Cerda flew through the 50K in 3:52:17! Paul Sinclair successfully defended last year’s first-place finish in the 100K with a time of 10:22:31. In the 100K, Angela Avina was the top woman and placed third overall with a time of 11:08:20. Zac Campbell and Jess Illg were the top man and woman in the 30K.
Wrap-up
My run went about as well as any 50K I’ve done. I had no issues during the race and felt good at the finish line and afterward.
Runners don’t expect a course to be exactly 50K — 31.1 miles — and the distance varies from race to race. The longest “50K” I’ve run was nearly 35 miles long and the shortest about 29 miles. My track for this race was just over 32 miles.
Angeles Crest Highway was still closed between Red Box and Vincent Gap, and the heatwave continued. I was trying to decide where to run.
I briefly considered the Circuit Around Strawberry Peak, but yesterday at 10:00 a.m., the “in-the-shade” temperature at Clear Creek was already 92°F, and the “in-the-sun” fuel temperature 109°F. By 1:00 p.m., the fuel temp reached a scorching 122°F!
Although trailheads such as Three Points and Islip Saddle couldn’t be accessed using Angeles Crest Highway, the highway was open from Wrightwood to Inspiration Point and Vincent Gap. After seeing the temps at Clear Creek, it took about two seconds to make the decision to head to the San Gabriels’ high country.

From Inspiration Point (7,365′), I ran east on the PCT about 7 miles to the North Backbone Trailhead on Mt. Baldy. Over most of that stretch, the temperature was a blissful 60-something degrees. Other times, I’ve driven to this trailhead — which requires a high-clearance vehicle — or run to the trailhead from Wrightwood. But the run along Blue Ridge is a favorite. It is especially scenic, with fantastic views of Mt. Baden-Powell, Iron Mountain, Pine Mountain, and Mt. Baldy.
Crossing the top of a chute on Mt. Baldy’s North Backbone.
Following a short descent, I resumed climbing the steep, somewhat loose ridge. After about ten minutes, I scrambled onto the crest of the ridge and crossed the top of a prominent, rocky chute. More than a thousand feet below, avalanche-hardened snow gleamed white in the sun at the base of the chute.
Another 10 minutes of climbing and I reached the Pine Mountain Juniper. Straddling the rocky crest at an elevation of about 9000′, this stalwart tree is estimated to be 800 – 1000 years old. It is a remarkable tree in a remarkable location. Except for one short, steep, eroded section, the remainder of the trail to the top of Pine Mountain (9648′) was relatively straightforward.
Dawson Peak and Mt. Baldy from Pine Mountain’s south summit.
Pine is the second-highest peak in the San Gabriels and has excellent views of the surrounding terrain. It is higher than Mt. Baden-Powell (9399′) and Dawson Peak (9575′) but a few hundred feet lower than Mt. Baldy (10,064′).
From Pine Mountain, the North Backbone trail continues over Dawson Peak another 2.5 miles to Mt. Baldy. There was still a long ribbon of snow along the east side of the upper North Backbone, but it looked like the trail might avoid it. I would have liked to confirm that, but today the top of Pine was my planned turnaround point. As it was, with the warm weather, I thought I might run short on water on the return to Inspiration Point.
Leaving Pine behind, I started back down — jogging when it made sense — but trying not to do anything stoopid. On the way down, I kept reaching behind me and squeezing the bladder in my hydration pack. I guess I was hoping that it would magically be more full than the last time I checked. It never was.

Back at the North Backbone Trailhead, and definitely low on water, I decided it was a good time to run the dirt road back to the top of the Acorn Trail and see how much shorter it was than the PCT. The answer was not much — only about a tenth of a mile.
I’d been willing to push the water envelope because it had been a heavy snow year. I expected the spring near Guffy Camp would probably be running. I’d passed the side trail to the spring a bunch of times but never ventured down the steep slope. My impression was that the spring was often low or nearly dry. This time when I reached the side trail, I headed down.

And down and down… It sure seemed like a long way to the spring, but when I checked the track, it was less than a quarter-mile with an elevation loss of about 200′.
Back on the PCT, the temperature was generally in the mid-eighties but was warmer on south-facing slopes. At about 1:00 p.m., the in-the-sun fuel temperature at the Big Pines RAWS was 109°F. I was very happy to have the extra water.
On June 1, Angeles National Forest reduced the size of the Bobcat Fire Closure, opening up most of the upper West Fork San Gabriel River area. Curious to see how the West Fork area is recovering from the Bobcat Fire, today I ran a slightly shortened version of the ANFTR/Mt. Disappointment 25K course.
Since the Mt. Wilson parking lot is usually closed until mid-morning, this morning’s run started and ended at a small turnout near the top of the Kenyon Devore Trail on the loop road on Mt. Wilson. The ANFTR Trail Races start at the main Mt. Wilson parking lot.
I’d recently done the San Gabriel Peak and Bill Riley Trails and knew they were in reasonable condition. And I’d read that AC100 Trail Work Teams led by Gary Hilliard and Ken Hamada had cleared the Gabrielino and Kenyon Devore Trails earlier this year. So, I didn’t expect to have a repeat of the epic fallen-tree obstacle course that I experienced doing this course in 2020.

Without a doubt, the Chumash Trail is one of my favorite short “after work” trail runs. Popular among hikers, mountain bikers, and runners, the Chumash Trail starts on Flanagan Drive in eastern Simi Valley and ascends the convoluted western flank of Rocky Peak Park to Rocky Peak Fire Road. It’s single-track trail all the way, gaining about 1175′ over 2.7 miles.
From a trail runner’s training perspective, it is a nearly ideal short, technical, higher heart rate workout. It has a few tough sections but is generally very runnable. When I’m chugging up the trail, it seems just about the time my heart rate is going to go lactic, the trail will back off or contour. Because I usually run the trail near my aerobic maximum, it’s a great indicator of where I am in my training. Over-training, or any other fitness issue, is usually plainly — and sometimes painfully — evident.
In many ways running down the Chumash Trail is more difficult than running up. It can be very challenging to run down a rocky, technical section of trail with any speed. Running a trail like the Chumash Trail can help develop the skill and strength necessary to do downhills with better technique and more speed.
I don’t think I’ve ever run this trail fresh, but a couple of times a year, when my legs feel good, it’s fun to really push the Chumash Trail up and down. Like most running, there’s a balance — push too hard on the up and there won’t be enough left to push the down.
Here is an interactive, 3D terrain view of the Chumash Trail Out & Back to Rocky Peak Road. The map can be zoomed, tilted, rotated, and panned using the navigation control on the right. Track and placename locations are approximate and subject to errors. Poor weather and other conditions may make this route unsuitable for this activity.
There are several ways to extend the basic out and back. One option is to turn left on Rocky Peak Road and run a mile to “Fossil Point.” Another is to turn right and run 1.6 mile to the Rock Peak overlook.
