Griffith Park Trail Runs.
The 10K at the Griffith Park Trail Runs is the shortest of six distances and still not a gentle one: almost nothing here is flat, and each kilometre averages close to 40 metres of climbing. Singletrack and fire road in Hollywood take you out and back along the same line, so prepare for constant changes of rhythm rather than for pure speed.
Griffith Park Trail Runs 2027: Course, Elevation & Route Profile
The start sits at around 155 metres, and within a few hundred metres the trail gains 50 metres over barely more than half a kilometre. One dip later the main climb begins at kilometre 2.3: just under two kilometres at about eight percent on average, taking you to roughly 330 metres. That stays well below the height every longer distance reaches.
At kilometre 5 you turn and run back along the same trails, and everything reverses. What was downhill a moment ago becomes a ramp of almost ten percent, and the long climb of the way out becomes the long descent home. Just past kilometre 9 a short kick of more than twelve percent is still waiting before the course drops to the finish.
Underfoot you alternate between narrow singletrack and wide fire road, and the course is well marked. There is hardly anywhere to catch your breath, since close to half the distance is steep, up or down. The organiser is Keira Henninger Races, whose Southern California calendar runs from 10K to 100 miles and is built around good marking and strong support.

Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
How to pace Griffith Park Trail Runs.
Start under control
Divide the race by effort, not by kilometre splits. The first ramp arrives before you are warm, and taking it at start-line speed gets billed on the main climb. What counts there is a stride you can hold for nearly two kilometres, even if it turns into a hike on the steepest pitches of around 16 percent.
Hold your rhythm
The race is decided around the turnaround. The ramp from kilometre 5 catches you straight off a descent, with quick legs and a heart rate that is too high: five calm minutes here are worth more than any fast downhill before it. At the top begins the part where you really gain time, because the way home falls for several kilometres.
Spend what is left
The trap sits close to the end. Run the long descent flat out and you meet the kick after kilometre 9 on shredded quads, and on average that is the steepest section of the whole course. Keep something back for it, since beyond its crest there is only downhill to the line.
Training plan for Griffith Park Trail Runs: 12-week build
Build the base
Expect roughly one to one and a half hours, depending on how much you hike. For that duration the effort is unusually restless: short climbs push you well into anaerobic territory, and the descents that follow bring little recovery because they are steep and demand full attention. A steady road 10K has very little in common with it.
Train race pace
So train the sequence. Hill intervals of three to eight minutes at high intensity mirror the main climb and the ramps. Place them on a hilly circuit so that you run downhill between repetitions instead of standing, and practise dropping straight back into a climbing stride after a descent, which is exactly what the turnaround asks of you.
Rehearse the course
Downhill running deserves sessions of its own, because just under half the course falls and about half of that is steep. Strength work for the quads and short, steep descents in training are what keep your legs intact for the way home and the last kick.
Arrive fresh
In the weeks before the race in late March, look for trails that alternate between narrow singletrack and wide fire road as these do. The narrow sections need sure footing and a short stride, the wide ones a willingness to pick the pace straight back up. A test run over ten kilometres with similar climbing tells you how hard you can really take the first long climb.
