Course & Terrain

One 22.3-mile opening loop followed by four 19.45-mile loops on the Pemberton, Shallmo, Cinch, and related park trails.

Key course features to know before comparing this race:

  • Four Peaks staging-area race headquarters
  • Repeated Pemberton Trail and Sonoran Desert loops

Rolling desert singletrack is more runnable than many mountain 100s, but heat, dust, exposure, darkness, and repeated-loop pacing remain significant.

Why This Race Matters

Javelina Jundred — 100 Mile is a useful reference point for runners comparing long fixed-distance ultras that still unfold over multiple days. Its format, terrain, and support model shape the kind of preparation required: not just fitness, but pacing discipline, nutrition planning, foot care, and the ability to make good decisions under fatigue.

Planning Notes

  • Prepare for sleep decisions, weather swings, and aid-station discipline. The distance is only one part of a multi-day fixed-distance race.
  • Treat intermediate cutoff gates as part of the course. Build enough margin for aid stops and late-race slowdown, and verify every current gate in the official rules.
  • Heat, sun, and dry air require event-specific preparation. Test sun protection and cooling, drink in response to thirst, and remember that sodium cannot make overdrinking safe.
  • The directory does not mark this as having simpler logistics. Confirm qualification, terrain, support, registration, medical, and withdrawal requirements before planning around it.
  • Wave starts produce different clock times for the final cutoff
  • Entry availability was waitlist-only at review
