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).
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.

Nobody sees it until we have read it. No account, no sign-in.
This changes nothing on the page on its own. Somebody checks it against the race first.
We want the address of the file the race publishes, not the file. We download it from there so the page can say where the line came from.
We read every one of these and we write back. Every fact here carries the source it came from, and the way a wrong one gets fixed is a person checking it against what you tell us.
NavRun builds your pacing from your own training, then turns it into a plan your crew can follow: when to leave and where to park.
