Why This Race Matters

Run Rabbit Run 100 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.
  • Train for terrain-specific fatigue. Technical trails and mountain courses demand downhill durability, hiking efficiency, and reliable night lighting.
  • The directory does not mark this as having simpler logistics. Confirm qualification, terrain, support, registration, medical, and withdrawal requirements before planning around it.
  • Hare and Tortoise fields have different limits and rules
  • Do not transfer one division's schedule to the other
