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.

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!
The Curve Fire started on Labor Day Weekend 2002, along Highway 39 in the San Gabriel Mountains. Between Mt. Islip and Throop Peak, the fire burned over the crest and down to Angeles Crest Highway. Between Throop Peak and Mt. Baden-Powell, the fire generally burned up to, but did not breach the crest.
The Curve Fire killed many trees, including some large, old-growth trees. The most common species along the trail between Mt. Islip and Throop Peak are white fir, Jeffrey pine, sugar pine, and lodgepole pine. Incense cedar also grows in the area, and limber pine is found on and to the east of Throop Peak. Here is a cross-section of a tree along the PCT about 3.0 miles from Islip Saddle. It is representative of the older trees killed in the Curve Fire.
Prior to the Curve Fire, the FRAP geodatabase of California fires has no record of a large fire that burned along the crest of the San Gabriels between Mt. Islip and Mt. Baden-Powell. The FRAP record extends back to the early 1900s, when the San Gabriel Timberland Reserve became Angeles National Forest. A study of mercury levels in Crystal Lake and newspaper accounts suggest the possibility that a large fire occurred in this area in 1878, or about 124 years before the Curve Fire.
I’ve run and hiked the PCT between Islip Saddle and Mt. Baden-Powell for many years, so have had the opportunity to follow the regrowth of conifers where the Curve Fire burned over the crest. Studying conifer regrowth in this area can provide insights into regrowth in the 2009 Station Fire and 2020 Bobcat Fire burn areas, and in areas burned by more than one of these fires.
This area of young trees is on a south-facing slope, just west of Throop Peak, about 5.1 miles east of Islip Saddle on the PCT. The elevation is about 8900 ft. Because of its aspect, the new trees are taller than in the other areas photographed. Here’s what this area looked like in May 2012, June 2016, and July 2022.
Nope, my eyes weren’t deceiving me, the hiker was carrying his full-size poodle up the trail.
I was running down the PCT, east of Islip Saddle, after a run/hike to Mt. Hawkins and Throop Peak. I’m guessing the hiker was carrying his dog to keep it out of the Poodle-dog Bush on both sides of the trail.
Poodle-dog Bush (Eriodictyon parryi) is a fire-follower that can cause severe dermatitis in some people. In this case the plants sprouted following the 2020 Bobcat Fire.
The last big outbreak of Poodle-dog Bush followed the 2009 Station Fire. At that time many people were unfamiliar with its potential effects, and were caught off-guard.
The plant can get you in a couple of ways — the plant’s resin can affect sensitized people in a manner similar to poison oak, and the plant’s numerous hairs can break off and irritate the skin.
Downtown Los Angeles (USC) ended the Rain Year (July 1, 2021 – June 30, 2022) with 12.40 inches of rain. This is about 87% of the 1991-2020 Climate Normal of 14.25 inches.
In part because of large amount of rainfall during December — nearly 9.5 inches at Los Angeles — and the meager amount of rain the previous year, the area’s vegetation responded as if there had been above average rainfall. Wildflowers bloomed in abundance and some trails became overgrown.
Earlier, as I was running up Las Llajas Canyon, I thought of a conversation I had with a runner during a 50K. The runner was from southern Florida, and talked about the difficulty of finding a good hill to run. It sounded like the main options are overpasses, bridges, buildings and stadiums.
In Southern California we have the opposite problem. It’s hard to find a trail run that doesn’t have hills. And the longer the run, the more likely it is you’re going to be running some hills.
The out and back in Las Llajas Canyon is one of the flatter runs that I do. From Evening Sky Drive it’s about 3.5 miles up to where the trail forks. There is a sign at the split indicating that the left fork leads to a private ranch, and the right fork connects to Rocky Peak Road.
On rested legs, the run up Las Llajas from Evening Sky Drive seems pretty flat. Over the 3+ miles up the canyon, the elevation gain is around 565′. That’s not a huge amount, but it’s roughly the equivalent of climbing 56 floors or 900 stairs. After leaving the Marrland aid station at 20 miles, runners doing the Rocky Peak 50K discover that the run up the canyon isn’t as flat as it looks!
If you want more distance or elevation, there are a couple of ways to extend the Las Llajas out and back. One is to take the right fork at the sign and continue up to the top of the hill just before Rocky Peak Road. This adds about 2 miles and 600 feet of elevation gain.
Another interesting way to extend the run, is to do the variation I was doing this morning. About halfway down the canyon on the way back, on the right, is a use trail. The use trail is about 1.6 miles from the turnaround point at the fork at the ranch sign. It is just past the area where steep cliffs tower above the road on the right, and is very easy to miss.
After turning right onto the use trail, about a half-mile up the trail splits. One trail switchbacks to the right and continues up to the top of cliffs and an old seashell grit mine; the other trail continues up the canyon to a pass between Las Llajas and Chivo Canyons.
The trail over the pass leads to a well-used trail that connects Chivo Canyon to Las Llajas Canyon near Evening Sky Drive. Some refer to this trail as the “Marr Ranch Trail.” This variation adds about 1.3 miles and 500′ of elevation gain.

After I got back from the run, I was curious to see what hilly trails there are in Florida. A quick search turned up the Hilly Trails In Florida page of the Florida Hikes web site. Anybody up for doing Mount Cockroach?
