Bandit Trail Runs Course Guide

Here is what you need to race the Bandit Trail Runs well: the Santa Susana course and where it gets won or lost, the real vert and the cutoffs, and a pacing and fueling plan built for climbing-heavy, sun-exposed Southern California trail. The distances are 50K, 30K, and 15K out of Corriganville Park, and I will walk you through it.

The course

The Bandit Trail Runs (formerly the Rocky Peak races) run a loop through the Santa Susana Mountains above Simi Valley, and they link the Rocky Peak, Las Llajas, and Tapo Canyon trail systems out of Corriganville Park, a former movie ranch sitting under the ridge. All three distances are cut from the same cloth: rocky fire roads, technical single track, sandstone-boulder ridge climbs, canyon descents, and wide-open mountain, city, and on a clear day ocean views.

A big climb early, then relentless rolling vert

The day opens with a long climb out of the canyon up onto the ridgeline, and it is the kind of steady grind that sets the tone for the rest of your race. Go too hard here and the exposure and the back-half climbs will collect the debt with interest. So power-hike the steep pitches from the gun and keep your early effort boring. Controlled.

After the ridge it does not really let up, it just keeps trading climbs for descents. The 50K links multiple named peaks across the Rocky Peak, Las Llajas, and Tapo Canyon area for about 5,411 feet of total gain over 31.08 miles, and the 30K takes on roughly 3,458 feet over 18.63 miles across two peaks. The 15K is the short one with a single main climb. The terrain runs roughly 60 percent fire road and 40 percent single track on the longer distances, so there is plenty of runnable ground if you have the legs left for it.

Exposure and footing are the real difficulty

This is high chaparral country: sandstone outcroppings, oak savannah, and almost no tree cover. So the course is nice to look at and almost fully exposed to the sun. There is very little shade, which means heat is not a side concern out here, it is the whole game when it comes to finishing well, and the late-September date can hand you real Southern California heat.

The single track throws in rocky, sometimes technical footing on both the climbs and the descents, so the descents are only a place to make time if you are confident on uneven ground. There is no real altitude (this is low coastal-range terrain, not the high country), and snow is a non-factor. The things that bite you here are heat, sun exposure, and the climbing that just keeps adding up.

Where the race is won or lost

On a course like this you lose the race two ways: you cook yourself on the early ridge climb, or you fall behind on fluid and sodium in the exposed middle. You win it by climbing patient early, being smart at the aid stations, and saving enough to actually run the fire-road descents and rollers in the back half when everyone around you is down to a shuffle.

For the 50K, the cutoffs reward staying ahead of the clock from the start. There is a hard 4:00 PM finish, with rolling aid-station cutoffs along the way (the Tapo station around mile 14 has historically had a late-morning cutoff, and the later stations tighten into the early afternoon). If you are racing the back of the pack, bank time early on the runnable stuff. Do not count on clawing it back late in the heat.

Pacing strategy

With this much vert, your flat-ground pace means nothing. Pace the Bandit by effort and let the terrain decide the rest.

Power-hike the climbs, run the descents

Treat the steep ridge climbs as hiking terrain from the very first one, not just the last. A controlled power-hike on a steep grade barely costs you any time over a grinding run, and it saves a ton of energy and heat. Then spend that saved energy on the fire-road descents and rollers, because that is where the strong Bandit runners actually pull away.

The cleanest way to check your effort on the climbs is grade-adjusted pace, which turns a hard uphill into the flat-ground pace it is really worth so you can hold a steady effort instead of chasing a number the hill will never give you. Run a recent hilly effort through the grade-adjusted pace calculator below and you will learn what your real climbing effort feels like before race day.

Set a vert-aware finish target, not a flat one

If you predict your Bandit finish from a road PR you will be way off, because road-pace math ignores 5,400 feet of climbing. A vert-aware projection that accounts for the gain gives you splits you can actually hold, and that matters double here because of the rolling 50K cutoffs. Build your target around the climbing first, then work backward to a start-line plan.

Fueling strategy

The Bandit is an exposed, sun-baked day. Fuel and hydrate for the heat first, then put the carbs on top.

Carbs steady, sodium and fluid biased for heat

For the 50K, aim for a steady 60 to 90 grams of carbohydrate per hour from a gut you have actually trained, and lean toward the lower end if you have not practiced high intake. The 30K and 15K can sit at the lower end of that band. The bigger levers on this course are sodium and fluid, because the exposure and the possible late-September heat mean you will sweat hard with no shade to recover in.

Bias sodium toward the high end of the 300 to 700 mg per liter range, and do not under-drink on the early climb just because it still feels cool. That deficit shows up later in the exposed middle. The plan you can trust is built from your own measured sweat rate plus the forecast, not some generic rule. Run your weight, goal time, and the expected high through the ultra fueling calculator and you get a per-hour carb, sodium, fluid, and caffeine plan you can rehearse on your long runs.

Carry between the aid stations

The 50K aid stations are spaced several miles apart over open terrain, so carry enough fluid to cover the gaps in the heat instead of running dry between stops. Use the aid stations to top off fluid, take in cold calories, and dump water on yourself to keep your core temperature down. Rehearse your carry and your hourly intake on hot training runs. That is what turns this plan from a number into a habit.

Bandit Trail Runs FAQ

How hard is the Bandit Trail Runs 50K?

It is a tough one. The 50K is about 31 miles with roughly 5,400 feet of climbing across the Santa Susana Mountains, and the ground is about 60 percent fire road and 40 percent single track. What makes it hard is the sustained ridge climbs, the exposed sun-baked terrain with almost no tree cover, and a late-September date that can bring real Southern California heat. None of the climbs are technical mountaineering. But the relentless up-and-down plus the exposure make it a far harder day than the mileage tells you.

How much climbing does the Bandit Trail Runs have?

The 50K carries about 5,411 feet of gain (and the same again in descent) over 31.08 miles, and it climbs multiple named peaks in the Rocky Peak, Las Llajas, and Tapo Canyon area. The 30K is about 18.63 miles with roughly 3,458 feet of gain over two peaks. The 15K is the short one with a single main climb. The race does not publish a vert number for it, so just plan on a meaningful early climb like the rest of this terrain gives you.

What is the terrain like, and is there shade?

It is a classic Santa Susana mix: rocky fire roads, technical single track, sandstone-boulder ridge climbs, and canyon runs, roughly 60 percent fire road and 40 percent single track on the longer distances. The country is high chaparral with sandstone outcroppings and oak savannah, which is nice to look at and almost entirely open. There is very little shade. Plan on direct sun for most of the day.

How should I fuel for the Bandit Trail Runs?

Fuel for heat and a long day in the open. For the 50K, aim for a steady 60 to 90 grams of carbohydrate per hour from a gut you have trained, and honestly the thing that makes or breaks you out here is sodium and fluid, not carbs. Lean toward the high end of 300 to 700 mg of sodium per liter and drink to your own measured sweat rate. The back half tends to feel hotter than the start, so do not under-drink early. Run your weight, goal time, and the forecast through the free ultra fueling calculator and you get a per-hour plan you can rehearse.

What are the cutoff times?

For the 50K, everyone has to finish by 4:00 PM, and there are rolling aid-station cutoffs along the way (for example, the Tapo aid station around mile 14 has historically had a late-morning cutoff, and the later stations tighten through the early afternoon). The 30K and 15K start later and share the same overall finish-line window. Aid-station times can shift year to year, so always check the current cutoffs on the official race site before race day.

How should I pace the climbs?

Pace by effort, not by your flat-ground pace, because the vert will wreck any even-split plan. Power-hike the steep ridge climbs early and bank that energy, and let the descents and the fire-road rollers be where you actually make time. The honest yardstick here is grade-adjusted pace, which turns your climbing effort into an equivalent flat pace so you do not blow up chasing a number the hills will never give you. Use the grade-adjusted pace and vert-aware finish-time tools to set real splits before you toe the line.
