Team RunRun’s Javelina Jundred Race Reports are your go-to resource for preparing for the Javelina 100 mile/100 kilometer runs! Our runners share what worked for them about the race, what they think you should know about the course, and rate it, so you can decide if the Javelina is the right event for you!
Choosing a running event is a big decision. Often it comes down to what your body is ready for, what your mindset is pushing you to do, and what your personality will like. That’s why at Team RunRun, we ask our runners to contribute reports of each race, so that you can get a sense for what the event will be like before signing up. Once you commit to the race, the reports are also valuable to help you prepare with appropriate training and gear. Read on for a summary of the Javelina Jundred plus a compilation of all the runner reports we’ve received (so far).
WHAT IS THE JAVELINA JUNDRED?
The Javelina Jundred is an annual 100-mile trail run with a fun twist – you can choose to run in costume to celebrate Halloween! Find out more details about the race from the organizers here. As you’ll see, you can choose to run the full 100-mile trail or opt for the shorter 100 kilometer course.
WHERE IS THE JAVELINA JUNDRED?
The Javelina Jundred takes place in Arizona. You’ll run 100 miles of the Pemberton Trail in McDowell Mountain Regional Park. Check out the below race reports to find out what tips our runners have about the course.
IS THE JAVELINA JUNDRED COMPETITIVE?
The organizers bill the Javelina Jundred as a social run – but that doesn’t mean it doesn’t get competitive! As you’ll see from the runner race reports below, the race attracts a lot of top athletes who make great times.
IS THE JAVELINA JUNDRED FUN?
The Javelina 100m/100k definitely rates as a fun race. In our Team RunRun race reports, we like to ask our runners what is weird or distinctive about a particular run. Many of them mention running in costume, the dance party at the end of the race, and the quirky awards. Keep in mind that the whole race is rated “R”, so you will have more fun without children!
WHAT KIND OF WEATHER SHOULD I EXPECT?
Arizona during the day in October is hot. If you read through the race reports from multiple years, you will see that it is generally in the 80s Fahrenheit (close to 30 degrees Celsius) and can get even hotter on the course, where there is little shade. It gets cold at night, so plan for layers!
IS THE JAVELINA JUNDRED WORTH RUNNING?
Take a survey of all our race reports – everyone loves this race! Even when Matt ran it with a sinus infection, he rated the race 5 out of 5 stars. Team RunRun says: sign up, have fun, and send us your race report when you are done!
HOW SHOULD I PREPARE FOR THE JAVELINA JUNDRED?
The Javelina Jundred is an ultra marathon, so you should definitely be comfortable with running ultra distances before signing up. Since the course is primarily in the sun, gets hot, and features a few hills, you will want to plan for running in the heat and add elevation to your training. Plus, plan for desert terrain, temperature swings, dark-to-light running, and guard against going out too fast.
Also, you might want to take some time to plan your costume so you can be a part of the Halloween fun!
WHAT SHOULD I KNOW ABOUT THE JAVELINA JUNDRED COURSE?
The Javelina 100 mile and 100k are run on a ~20 mile rolling single track trail in McDowell Mountain Regional Park near Fountain Hills, AZ. It’s a well-supported, easy race to crew for, as it all takes place in the park, with one main crew access point. Very runnable trails make for faster times, but the exposed, desert heat along with chilly nights after sunset can make it very challenging. The Jackass Night Trail, added in 2018, gives you the option to run either 31k or 62k distances.
The 100k runners complete 3 loops while the 100m runners complete 5, and they are run “washing machine” style, meaning each is reversed. Each loop has a gentle 800 foot climb from the start/finish at Javelina Jeadquarters to the high point near the foothills of the McDowell Mountain range. The trail dips in and out of wash beds on the far side of the course and the footing is a mix of hard packed granite, rocks and sand. Total gain for each loop is ~1580 feet.
JAVELINA JUNDRED ELEVATION BREAKDOWN
Longest climb: 800ft over ~10.5 miles. Climb begins after you leave the Javelina Jeadquarters each time. Each loop gains about 1580 feet.
Steepest climb: N/A because you repeat the same climb over and over again each lap
JAVELINA JUNDRED AID STATIONS
Plan for where the aid stations are (and check out our race reports for what runners wish they had done differently at the aid stations):

QUICK GLANCE – LESSONS LEARNED FROM OUR RUNNER RACE REPORTS
Here are some of the lessons learned from our runners at the Javelina Jundred:
Lessons about gear
- You will need a headlamp at the start of the 100 miler, though you can get away with a small one given you’re around so many runners.
- Gaiters are helpful in keeping small pebbles out of your shoes
- Trekking poles are not allowed, but music is
- Have a good ice bandana and possibly arm sleeves to stick ice in them
- Have crew have a cooler with cold water and ice, and a towel to wrap around you each time, thus cooling down your core temperature each loop
- Consider changing socks often, or at least have that option available
- Lube up with so much small dirt getting in places and causing chaffage
- Use any ice water you can at aid stations to pour on yourself and cool down
Lessons about the course
- Be prepared for very hot, exposed daytime running, and cold nighttime running once the sun goes down. Have layers on you after 3pm.
- Because the course is so runnable, it’s easy to go out fast, especially in cooler morning temps
- Be sure to carry enough water between aid stations, especially the 6.5 mile stretch that you will run 6 times
- Despite being a flatter, more runnable course, it still has a high DNF rate each year (at least 50%), largely because of the heat and going out too fast
- 3rd loop is likely the hottest one of the day (out of 5 loops)
- There is no shade for runners and barely any for crew.
- It’s not the most technical trail or the hilliest, but each ensuing loop will seem more so on tired legs and mind
- There are lots of runners out on the course and it thins out over time, but be prepared for feeling like there are a lot of people in the event, especially with the washing machine style loops
- If you’re a fast 100k runner, you’ll likely have lots of people to pass in the 100 miler as you catch them, as you start an hour after them
- The heat of the day feels so much hotter than the temps say, simply because there is no shade anywhere
- Pacers are helpful in this race to help break the monotony of running the same loop 3-5 times
