Javelina Jundred Ultra Marathon: Powering Your Race Weekend
Get ready for a unique ultra experience in the rugged desert trails around McDowell Mountain Regional Park, just outside Phoenix, Arizona. The Javelina Jundred stands out with its fun, party-like atmosphere, gorgeous views, and quirky awards.
Happening every year on the last weekend of October, this overnight race will challenge you mentally and physically. Training for it requires serious commitment, and figuring out what to pack is just as important.
This guide will help you figure out exactly what you need for race weekend to stay prepared and powered.
Drop Bag
A small drop bag can be filled with extra supplies at dedicated spots along the race. The Javelina Jundred offers two drop locations, so label your bag clearly with your bib number, name, and the aid station location where it needs to be. Fill it with extra clothes, snacks, or whatever else you might need mid-race to keep you going.
Head Torch
Running at night means a good head torch isn’t optional. Find a lightweight headlamp with adjustable brightness and solid battery life. Pack extra batteries to avoid being caught in the dark, especially in the more remote parts of the trail. Practice with your head torch before game day to ensure it fits comfortably so you don't have to fiddle with it during the race.

The high-efficiency solar panel delivers a consistent charge in the desert, providing 600W of AC output through the power station. It’s the best solar generator for any ultramarathon need.
Cellphone
Your mobile device is a must for an ultramarathon. While running, use it to play music and monitor health information. Don't forget to charge your headphones before the event.
Cellphones are also handy in case of emergencies. At Javeilne Jundred, trained medical staff can be reached by dialing their number on the running bib. Signage throughout the trail helps staff pinpoint your location for faster help.
Mini First Aid
Customize a compact first aid kit to carry on your person while running to attend to minor issues quickly. Your kit should include items like blister bandages, moleskine, antiseptic wipes, bandages, and a small tube of chafing balm.
Add ibuprofen for muscle soreness and electrolyte capsules. Pop blisters safely with tweezers and safety pins. Don’t hesitate to seek help from aid stations along the trail when needed.

The convenient magnetic snap-on design lets you securely attach it to your phone or other gear to charge up without hassle. It offers 15W wireless charging and 65W when charging through the USB-C cord.
Hydration
A hydration plan is essential for Javelina Jundred. Aim to drink small sips consistently and add electrolyte drink mixes to prevent cramps. While four aid stations are equipped with water, Gatorade, soda, broths, and coffee, you shouldn’t rely on them as your sole source of hydration. Carry enough water in a hydration vest or handheld bottle to use between stations in case of delays, getting off course, or unexpected heat.
Change of Socks and Layers
The dusty desert trails of the Javelina Jundred can get extremely hot during the day, leading to excessive sweating and grit buildup, which can cause blisters. Pack extra socks in your drop bags to change into between loops and keep your feet dry and protected. Include thermal layers like gloves, a beanie, and a long-sleeved tee in your bag as well to slip on when it gets cool at night.

Food
While the aid stations are well stocked with sweet and salty snacks like cookies, fruit, and chips, and fully prepared meals like pizza and sandwiches, you should still carry some of your own. You still need to pack snacks and food you’ve trained with to have when you need them. Eating consistently and early in the race supports endurance during long trail hours.
