Javelina Jundred

Javelina Jundred is unique among top 100 mile races in that the course consists of loops that all begin and end at race headquarters. Though fall temperatures are relatively cool for the Sonoran Desert, the course is still completely without shade and daytime temperatures can reach up into the 90s. Heat is often one of the top reasons for runners to drop from the race, though at night temperatures drop rapidly. Held in late October around Halloween weekend, the race has a unique culture with many runners wearing costumes, and unconventional awards such as best costume and best ass. Race organizers typically warn participants and crew that the race is "R rated". == History ==
