Summary: A costumed trail run party in the desert over the weekend of Halloween, the Javelina Jundred 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.
Course Description (adapted from race website): The 100 mile course will incorporate five ~20 mile loops on trails that feature rolling single track through the Sonoran Desert. 100 kilometer runners will compete 3 loops. Loops are run “washing machine” style, meaning each is reversed. Each loop features 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 before descending back to the start finish. The trail is a mix of hard packed granite, rocks and sand.
Lessons Learned from Race Reports
- You will need a headlamp at the start of the 100 miler
- Be prepared for very hot, exposed daytime running, and cold nighttime running once the sun goes down. Have layers on you after 3pm.
- Aspects of the race to train for specifically: Heat, Desert Terrain, Going out too fast, Temperature Swings, Lighting
- 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
- Gaiters are helpful in keeping small pebbles out of your shoes
- For it 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)
Longest climb: 800ft over ~10.5 miles. Climb begins after you leave the Javelina Jeadquarters each time
Steepest climb: N/A because you repeat the same climb over and over again each lap
