When I parked at Malibu & Piuma to do the Bulldog Loop on Sunday, I didn’t know that I was going to be swept up in a Bulldog Ultra training run.
I had just started up Bulldog Mtwy fire road when the first group of speedy runners swarmed past. The strenuous climb to the Castro Peak Mtwy gains about 1750 feet over 3.4 miles. Much of its infamy is due to the oven-like conditions typically experienced on the second loop during the Bulldog 50K.
This morning, the climb was a little warm in spots, but not bad. There was a good turnout for the training run and nearly everyone was enjoying the run.
On the way up I had an interesting conversation with a runner that had just done their first 100 miler and was going to pace someone in the AC100 this weekend.
Here’s an interactive, 3D terrain view of the Bulldog loop. The map can be zoomed, tilted, rotated, and panned. To change the view, use the control on the upper right side of the screen. Track and placename locations are approximate and subject to errors. Poor weather, and other conditions may make this route unsuitable for this activity.
Good luck to all the runners doing Bulldog — especially those doing their first trail race or ultra!
The Angeles Crest 100 Mile Run has always been considered a challenging 100 miler. This year it’s going to be even more challenging. Because of trail closures related to the Bobcat Fire and subsequent heavy runoff, this year’s course will be from Wrightwood, out to Shortcut Saddle, and back.
One of the main reasons it will be more difficult is that the course will, on average, be at higher altitude. According to Google Earth, the average elevation of previous AC100 courses has been around 5100′-5300′. This year’s course averages nearly 6900′.
Another big difference is that in the last 25 miles there will be two tough climbs on the highest sections of the course — the climb from Islip Saddle to Baden-Powell, and the climb from Vincent Gap to Blue Ridge.
And, as if that wasn’t enough, most calculate that the cumulative elevation gain is greater on the 2022 course than previous courses. The estimated elevation gain on the AC100 website for this year’s course is 23,228′.
Because of the increased difficulty, cutoff times have been adjusted and the overall time to complete the course has been increased to 36 hours — from 5:00 a.m Saturday morning to 5 p.m. Sunday afternoon.
The elevation profile of the 2022 AC100 course (PDF) was created in SportTracks from the GPX file on the AC100 website. The profile uses elevations corrected with pkan’s Elevation Correction Plugin and 3DEP 1-meter Lidar-based DEMs and a conservative elevation data smoothing setting.
Placemark locations, mileages, and elevation gains and losses are approximate. See the AC100 website for much more information and details. For comparison, here is an elevation profile from the 2017 AC100. Note that the 2017 profile was created using a GPS track from a runner and calibrated using lower resolution (1/3 arc-second) DEMs.
The race starts on August 6, 2022 at 5:00 a.m. in Wrightwood, California. There is a button/link for Runner Live Tracking on the AC100 Home Page. If you are participating, have a great race!
Just 48 hours before the start of the Diablo Trails Challenge the temperature on Mt. Diablo’s summit was a chilly 31°F. Gray, wind-driven clouds shrouded the summit, propelled by 20-30 mph winds. Over the 10 days preceding the race, it had rained on four, and Concord had received about two inches of rain.
That’s the thing about Spring weather – a couple of days can make a huge difference. Today – race day – the sun is out, the hills are green and skies blue. Very little mud remains – the trails are in great shape and hills sprinkled with wildflowers. It’s the perfect day for a run on Mt. Diablo!
With around 7000′ of elevation gain/loss, the Diablo Trails Challenge 50K is characterized by its many ups and downs. The core of the 50K course is the 7 mile, 3000′ climb from the Curry Canyon Ranch aid station to Diablo’s main summit. But before you can enjoy this fine ascent, you have to get to Curry Canyon Ranch. And it’s on the other side of the mountain – about 12.5 miles away. Here’s a 3D interactive view of my GPS track of the 50K course.
Along the way there are several get-your-feet-wet creek crossings and many hills. Following along on the map, the course works its way past Wall Point, Artist Point, Knob Point and finally Windy Point. Did I mention the course is hilly?
Somewhere around Mile 10 you get the first good view of Mt. Diablo and North Peak. The runner in front of me exclaimed, “Holy guacamole, is that what we are going to climb?” My choice of words were similar, but not quite as polite. Yes indeed, those were the peaks, and they loomed LARGE across the valley.
Elevation gained is so easily lost. After gaining about 2500′ on the way to Windy Point, a 1000′ descent leads to the Curry Canyon Ranch Aid Station. The climb of Diablo starts here, but you really don’t feel like you’re on the mountain until you reach South Gate Road and the Curry Point Aid Station, about three miles up the canyon. The grade in Curry Canyon is moderate and I tried to take advantage of that, knowing steeper terrain was ahead.
The Half-Marathoners joined the course at Curry Point — adding their enthusiasm and company – but they were soon headed back down, leaving us to cope with the Summit Trail all on our own.
“Jalapeño chip?,” I asked the runner hiking up the hill next to me. He smiled and said something like, “Maybe next time.” I did what I could to keep from constantly looking up at the summit. I munched on chips, talked to runners and hikers, read the “Trail Through Time” interpretive signs, looked at wildflowers and enjoyed the great views. As long as you keep putting one foot ahead of the other — and maybe smile from time to time – summits will eventually arrive.
Yahoo! The Summit Aid Station! There is almost no wind. In the sun it’s comfortably warm and in the shade comfortably cool. As at the other aid stations, the volunteers are great, helping me to get my hydration pack sorted and get me on my way. After seven miles of uphill, a little downhill is going to feel really good.
The next few miles I’d done before and they are among the most interesting on the course. It helped to be familiar it – especially the notoriously steep section of North Peak Road, just before the summit. Everyone picks a different route. This time I stayed on the left going up and the right going down, and didn’t fall on my butt!
Once past the “slide” it didn’t take long to get down to Prospector’s Gap. I recalled that the running on the Bald Ridge Trail was excellent and wasn’t disappointed. At Meridian Ridge Road we left Bald Ridge and descended into Mitchell Canyon. At Deer Flat Creek, once again the course headed up. I couldn’t recall how long the climb was going to be, but it looked like we were going to have to work over a high ridge to get to the Castle Rock side of the mountain. The ridge turned out to be Moses Rock Ridge and the climb over it fit right in with the other hills on the course. Click, click goes the elevation-gained counter.
Most of the course is a big loop, but to access the peaks and aid stations there are four short out and back sections. You get to know the runners around you on these sections and we’d give each other encouragement as we passed. The runners around me were great and throughout the run we had many good conversations.
Then there was Burma Road. Somewhere around mile 26, I commented to another runner that we were running out of miles and at some point we were going to have to lose a lot of elevation. The Burma Road descent took care of that.
Many thanks to Jasmin and Sam of Brazen Racing for putting together such a superb event! And a BIG thank you to all the volunteers, ham operators, runners, park staff, sponsors and especially the Save Mount Diablo Foundation. I thoroughly enjoyed running on Mt. Diablo!
I looked at the mileage on my Garmin watch — 11.93 miles. I was at Kanan Dume Road and debating whether to make Kanan my turnaround point. My run had started at Malibu Canyon Rd. & Piuma Rd., where I’d picked up the Sean O’Brien Trail Runs course at around mile 2. After crossing Malibu Creek, the 100K, 50M, 50K and Marathon courses all follow the Backbone Trail westbound from Malibu Canyon.
The ground had been spotted with raindrops as I started the nearly 3 mile, 1500′ climb out of Malibu canyon. Subtropical moisture was streaming in from the southwest and there was a broad swath of clouds over Southern California. There were scattered showers, but most of the rain was evaporating before it reached the ground. The last time it had rained was more than a month ago, and the smell of rain was intoxicating.
Two weeks ago I’d done this climb as part of a “reverse” Bulldog loop. It hadn’t become any less steep. Most of the climb is on a fire road and some of it is runnable — just how runnable depends on your VO2max, determination and inclination. It was a relief to reach the top and start running downhill, even if another climb loomed just ahead.
From Corral Canyon the Backbone Trail drops into Upper Solstice Canyon. Today, the 16 crossings of the small creek in the canyon were all dry. Someone had provided log seats under a sprawling oak at “heart” meadow. I had to stop for a moment just to enjoy its tranquility. On a run here in January several years ago, the area was covered in ladybugs.
The high point of the 50K course follows the climb out of Upper Solstice Canyon and is near the saddle at Newton Mtwy. Back in the day the Bulldog 50K used to climb up and over the shoulder of Castro Peak from the top of Bulldog; then descend to this saddle and continue to Corral Canyon on the Upper Solstice Canyon Trail. This 2004 Los Angeles times article describes why the road is now gated and private.
The day was a little warmer than expected and the shaded sections of trail in Newton Canyon were refreshingly cool. The dried out stalks of last year’s hummingbird sage were common along the trail and given the lack of rain, I was very surprised to find a plant that was blooming.
The Sean O’Brien Marathon turns around at Kanan Dume Road, which is what I should have done. That would have resulted in a pleasant 24 mile training run with a bit over 5000′ of gain. Instead I decided to continue west on the Backbone Trail and “just run down to the bridge” to see if there was any water in Zuma Creek. There wasn’t. The bridge also would have been a perfectly good turnaround point that would have netted a 26 mile run.
But it was one of those rare, long run kind of days where the mind and legs are in sync and the miles almost didn’t matter. I reasoned that the Sean O’Brien 50K turnaround was “only” another mile and a half away, so why not continue. That way I’d have an even better idea of what to expect on race day.
I did continue, and with the exception of running low on water, everything went well. At Latigo Canyon several runners had just returned to their cars and I was able to fill up my Camelbak(R). Thanks Lou! And thanks to the other runners at the trailhead for their offers of gels, beer and salt!
I’ve run that section of the Backbone Trail several times, but never as an out and back. I now understand why the times for the Sean O’ Brien 50K are a little longer than the typical 50K. For one thing the course is about 1.5 mile longer than a 50K. For another, it has a TON of elevation gain. Using the elevation profile from my fenix 3 and a 1/3 arc-sec DEM from the USGS, the hand-calculated elevation gain worked out to be around 6000′. Tack on another 500′ of gain to account for the Tapia Spur Trail and the total gain for the Sean O’Brien 50K works out to a stout 6500′, give or take.
I had heard runners behind me since the last aid station. Now that we had passed the 8000′ high point of the course and were headed downhill, the group was going to pass me. I was at about mile 47 of the Kodiak 50 Mile race, and trying to shake off some demons that had been plaguing me for the last 7 miles.
It was my fourth Kodiak 50M and except for these last few miles it had been a mostly enjoyable day on the trails and forest roads of Big Bear Lake. There is no better run than a run in the mountains, and for my money no better 50 Mile race in Southern California than the Kodiak 50M. The Kodiak races (100M, 50M, Front 50K, Back 50K) have a character all their own, and at least for now — no lottery or histrionics. Just enter, train hard and then run!
The race had started before dawn near Fawnskin, on the north side of Big Bear Lake. It had been a chilly forty-something degrees at the trailhead, but warmed quickly as we ascended the Grays Peak Trail. Today would be the first day of a record-setting heat wave in SoCal and temps for the race would be the warmest in its five year history. By the time we reached Snow Valley and were descending the windless, exposed, south-facing slopes of Bear Canyon, the “in the sun” temps would be around 100.
The highlight of the 50M race for me is the climb out of Bear Canyon on the Siberia Creek Trail. This classic 7 mile ascent gains around 2910′ from Bear Creek (4770′) to the Champion aid station (7680′). You only get to do the Siberia Creek climb when the 50M is run counter-clockwise around the west end of the lake. This has been the case each year except for 2016.
Expecting it to be hot and knowing how tough this climb can be, I filled my Camelbak(TM) to the brim and also took an extra bottle. (Thanks Aaron and Lacey!) What I didn’t do was take the time to cool off in the stream. A couple minutes of cooling here might have helped keep the race demons at bay.
It was deceivingly cool in the shade of the trees along Bear Creek, but that didn’t last long. By the time I got to the top of the Siberia Creek climb I was just about out of water, dehydrated and over-heated. I laughed when I thought about how cold it was here in 2013. That year racers resting at the Champion aid station huddled in blankets and sipped hot soup to try and stay warm. Not today! I tried to take the time to rehydrate, but the clock was ticking. I grabbed a cup of ice and started up the fire road.
Though still generous, the cutoffs for the 50 milers have been substantially tightened since the 2015 event. Descending from the Grandview aid station to the Aspen Glen aid station I knew I was close to the cutoff and that was confirmed when a runner coming up the trail told me I only had 5 minutes remaining. The aid station personnel at Aspen Glen were phenomenal and I was in and out of there with water, my headlamp, and a couple of GUs in 48 seconds. I was excited to have made the cutoff, but knew I was going to have to push it to make the Finish by 9:00 p.m.
I had forgotten just how far east the Pine Knot Trail goes before ascending to Grandview. At one point it seemed the trail was going to descend all the way to the lake. I hadn’t seen a trail marker in some time and no other runners were in sight. I began to think I might have missed a turn and stopped to look more closely at the tracks on the trail. The imprints of a Brooks Cascadia and Altra Olympus stood out from the others. They were as good as a trail marker, and assured me I was still on course.
Eventually the Pine Knot Trail and I found our way back up to the Grandview aid station, but somewhere along the way I had become nauseated. Without asking, my body decided blood would be more useful for cooling and propulsion than for absorbing fluids and nutrients. My stomach had one message for me, “Sorry, we are closed!” It’s a common issue in longer runs, and given time, most runners work through it.
Unfortunately time was at a premium; all I could do is ralph, turn onto the Skyline Trail, and take the first steps toward the last aid station. I felt a little better after that and could sip a little water. The good news was that along with the sun, the temperature and my water requirements would be going down. What wasn’t going down was the trail. My recollection of this section was that it was a long five miles, but I did not recall all the ups along the way.
The last mile of the trail to the aid station paralleled the next section of the course and from time to time a runner would shout encouragement from the road above. I’d hoped to make it to the last aid station without having to stop and put on my headlamp and pulled into the station by the light of a quarter moon. Still nauseated, I put on my light and headed up the road.
Like a wrangler movin’ stock down from the high country, sweep Vanessa Kline encouraged the group of runners. We only had about 3 miles to go.
“You gotta keep running! You can do it! If you don’t run, you won’t make the cutoff!”
Most of the group did just that; they kept running and made the cutoff. Despite Vanessa’s best effort to get me moving a little faster, I crossed the finish line seven minutes after the 9:00 p.m. deadline.
I would have liked to make the cutoff, but I’m OK with the unofficial finish. I wasn’t trying to get UTMB points or to qualify for a 100 mile — I was running Kodiak for fun. I like the course and the way the event is organized. I’ve had faster Kodiak times and I’ve had slower. What didn’t change was that I was still smiling at the Finish.
The heat was oppressive. The air was sweltering and still, reminding me of hot nights in the South, when heat lightning flashed on the horizon, and any movement was an effort. An adductor muscle in my left leg started to cramp and I jumped up from the reclining chair. Heat, and more heat had been the theme of this day. I had returned home from running my eleventh, and hottest, Mt. Disappointment 50K, only to be caught in a widespread power failure caused by a transformer explosion and fire in a Northridge distribution station.
How hot was it for the 2017 Mt. Disappointment races on Mt. Wilson?
– Between 11:00 a.m. and 5:00 p.m. the in the sun temps recorded by the Clear Creek RAWS (on the 50K course) ranged from 115 °F to 121 °F. Out of the sun temps ranged from 94 °F to 98 °F.
– Between 10:30 a.m. and 4:30 p.m. an ANF portable weather station adjacent to the Mt. Wilson Observatory recorded in the sun temps ranging from 106 °F to 114 °F. Out of the sun temps ranged from 92 °F to 96 °F.
– The temperature (inside a ventilated instrument housing) on Mt. Wilson at CBS Radio reached a high of 103 degrees. This appears to be the highest temperature at that location since it came online in 2008 and may have been the hottest temperature on Mt. Wilson in several decades.
– Downtown Los Angeles (USC) reached a record high for the date of 98 degrees, breaking a 131 year old record.
Even more remarkable than the weather were the performances of the top runners. Ruperto Romero was the overall winner of the 50K with an astounding time of 4:38:44. This was only a couple of minutes slower than his winning 2015 time — when temps were 20-30 degrees cooler. In what must have been an exciting finish in the Women’s division, Elizabeth Ochoa cranked out a 6:19:45, just edging out Ana Guijarro by eight seconds. Victor Martinez won the 25K in 2:08:01, with Jay Nadeau taking the top women’s time in 3:05:13. All the Mt. Disappointment results are available on UltraSignup.
The heat continued to build past noon, peaking between 1:30 p.m. and 4:30 p.m. This made for a long day for those of us in the back of the pack. At 1:00 p.m Red Box Road was a blast furnace, facing directly into the sun. I was very glad to have scouted the final seven miles of the course last weekend. The creeks crossing the road really helped to keep from becoming over-heated. Strayns Creek on the Kenyon Devore climb also helped me to cool down.
Many thanks to Gary and Pam Hilliard and all the Mt. Disappointment staff, volunteers, sponsors and runners. The aid station personnel were phenomenal, and all their assistance was much appreciated. The efforts of the Forest Service were also much appreciated. ANF personnel were on the trails and at the aid stations, helping runners.
