The course

Where it goes multi-loop · 21 aid stations · rust marks a stop your crew can reach

A washing-machine multi-loop 100 miler: one 22.3-mile loop via the Escondido Trail followed by four 19.45-mile loops on the Pemberton, Shallmo and Cinch Trails, all clockwise from Javelina Jeadquarters, all through the same four-station sequence (JQ, Coyote Camp, Jackass Junction, Rattlesnake Ranch) every lap; only the final leg back into JQ differs by loop (Escondido on loop 1, Pemberton/Cinch on loops 2-5). The 2026 Javelina Jundred 100 Mile is a Western States 100 qualifier for the 2027 lottery (finish under 30 hours to be lottery-eligible) and a Western States 100 Golden Ticket race: the top 2 men and top 2 women automatically qualify for the 2026 Western States 100, with the bid sliding to 3rd, 4th, then 5th place if a higher finisher is already entered in WSER or declines (no lower than 5th accepted).

SCHEMA GAP (non-uniform multi_loop, see _meta.notes): loop_distance_miles is left null because this course has TWO loop lengths, not one -- 22.3 miles for loop 1 (via the Escondido Trail) and 19.45 miles for each of loops 2 through 5 (via the Pemberton, Shallmo and Cinch Trails). Computed total: 22.3 + 4(19.45) = 100.1 miles, against a published headline of "100 Miles". Elevation gain (+6,296 ft) and high/low points (2,486 ft / 1,623 ft) are the race's own published Key Stats; no elevation LOSS figure is published and none is computed here (no GPX was found to derive it from, unlike Western States).

The race

What this one is

A costumed, Halloween-weekend 100 mile (plus 100K and 31K) trail run on a roughly 20-mile loop of the Pemberton Trail system in McDowell Mountain Regional Park near Fountain Hills, Arizona, run out of a single desert basecamp ("Javelina Jeadquarters") that runners, crew and campers share for the whole weekend. Billed by its own organizers as "the original costumed 100 mile trail run party."

Founded in 2003 by Phoenix ultrarunner Geri Kilgariff as a joking idea with running partner Anthony "Woofie" Humpage while running the Pemberton Trail; Kilgariff expected maybe 50 entrants and got 180. The race was won that first year by Stephanie Ehret, one of the first 100-mile races won by a woman. Directed by James and Rodger Wrublik for several years, then by Jamil Coury starting in 2008; Coury founded Aravaipa Running in 2009, which has organized Javelina ever since.

Crew rules
Crewing is allowed ONLY at Javelina Jeadquarters (the start/finish); there is no crew access anywhere else on the loop, so crews never drive between aid stations -- they see their runner roughly every 20 miles by staying at JQ. Crews may set up pop-up canopies (10x10 recommended) in designated crew areas outside the camping zones, reserved in advance during registration for a $100 fee (one crew space per runner registration, up to ~4 runners sharing a canopy recommended). Aid station food and drink at JQ is for runners and pacers only. Two Community Crew Spaces are set aside at JQ for runners who could not secure a reserved crew space. No pets anywhere on site. The event is R-rated (explicit music, risque costumes; frontal nudity not permitted). aravaiparunning.com
Pacer rules
One pacer at a time (multiple pacers may be used across the race, swapped only at JQ). Pacers must be human and on foot -- no pets, no bicycles, no muling or carrying the runner's gear/supplies. Pacers can only be picked up and dropped off at Javelina Jeadquarters, so every pacer must be prepared to complete a full ~19.45-mile loop; no exceptions. Pacers are allowed starting after 3 loops (61.2 miles) OR at sunset, whichever comes first: a runner leaving JQ at 5:00 PM or later to start loop 3 may take a pacer from that loop, even before the 61.2-mile mark. All pacers must sign a waiver and wear a designated pacer bib. aravaiparunning.com
Drop bag rules
Two drop bag locations: one at Javelina Jeadquarters (accessible after every loop) and one remote bag at Jackass Junction (roughly halfway/mile ~9.45 into each loop per this file's derivation), which is transported out before the first wave start and returned to JQ by 12:00 PM Sunday. Bags should be labeled with name, bib number and aid station location; waterproof bags/containers recommended; large duffel bags, suitcases or coolers will not be transported to Jackass Junction. aravaiparunning.com
Cutoff philosophy
Two waves start 30 minutes apart (6:00 AM sub-24-hour-eligible wave, 6:30 AM wave); every cutoff is enforced against YOUR OWN wave's gun time, not a fixed clock time, so a Wave 2 runner's cutoffs all fall exactly 30 minutes later than the times shown here for Wave 1. The race publishes only two gates for the whole 100.1-mile distance: you must start your 5th and final loop (80.65 miles in) within 24 hours of your own wave start, and you must finish within 30 hours of your own wave start. No published intermediate cutoffs exist for starting loops 2, 3 or 4. Finishing within 24 hours of your own wave start (independent of the loop-5 gate, though numerically coincident with it) earns the larger sub-24-hour buckle instead of the standard finisher buckle. aravaiparunning.com
