The course

Where it goes multi-loop · 13 aid stations

The same washing-machine loop as the 100 Mile, run for one 22.3-mile Escondido loop plus two 19.45-mile standard loops (computed 61.2 mi total against a published '62 Miles' headline; see _meta.notes conflict (5)). Same four-station-per-loop sequence and same single crew point (Javelina Jeadquarters) as the 100 Mile. Not a Western States qualifier or Golden Ticket race (that status applies to the 100 Mile only).

SCHEMA GAP (non-uniform multi_loop): loop_distance_miles left null -- loop 1 is 22.3 mi (Escondido), loops 2-3 are 19.45 mi each. Computed total 22.3 + 2(19.45) = 61.2 mi. CONFLICT: the race's own Key Stats headline this course as "62 Miles", an 0.8 mi gap from the computed total; see _meta.notes conflict (5). A stale September-2025 snapshot of this same page briefly showed "three 19.45 mile loops" for the 100K (which would total 80.65 mi, actually the 100 MILE's loop-4 figure) -- an evident copy-paste error since fixed on the current live page ("two 19.45 mile loops"); not used for any fact here, noted only as a caught trap. Elevation loss not published.

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
Identical to the 100 Mile: crewing only at Javelina Jeadquarters, reserved canopy spaces, R-rated event, no pets. aravaiparunning.com
Pacer rules
Same rules as the 100 Mile (one at a time, human, on foot, JQ pickup/dropoff only, no muling). Eligible after two loops (41.75 miles) or at sunset, whichever comes first: leaving JQ at 5:00 PM or later grants an earlier pacer pickup. aravaiparunning.com
Drop bag rules
Same two drop bag locations as the 100 Mile: Javelina Jeadquarters (every loop) and Jackass Junction (remote, transported before the first wave, returned by 12:00 PM Sunday).
Cutoff philosophy
Single wave, 7:00 AM start. Two published gates: must start the 3rd and final loop (41.75 miles in) by 6:00 AM Sunday (23 hours elapsed), and must finish by 12:00 PM Sunday (29 hours elapsed, matching the published 29-hour time limit exactly). No published cutoff for starting loop 2. If a runner drops from the 100 Mile race, they are scored a 100-Mile DNF and are NOT credited a 100K finish even if their distance covered would otherwise qualify -- there is no down-distance switch. aravaiparunning.com
