Qualifying for Eastern States

The Eastern States 100 is not an entry-level ultramarathon. The course terrain, elevation gain, and weather conditions present unique challenges that require significant prior trail running experience.

Minimum Qualification Requirement

  • Timing: The qualifying race must take place between January 1, 2024, and the date of registration.
  • Official Event: The race must be an officially organized trail event with publicly available results.

Non-Qualifying Events

  • Timed Events: Includes 12-hour, 24-hour races.
  • FKTs: Fastest Known Times, peak bagging, or Long-Distance runs/hikes.
  • OCR: Obstacle Course Races.
  • Biathlons/Triathlons: Unless the run portion is a 50K trail race.

Completion Requirement

  • 50K Completion: Participants must complete the qualifying 50K prior to registration to be accepted.
