Qualifying for 2023 Events

We often receive questions asking for clarification of whether a runner is qualified to compete at one of our events. Here is a brief overview of what counts, and what doesn't.

Please note that these are the absolute minimum qualifications required in order to start. We advise gathering a great deal more experience than a single qualifier before attempting the 50 mile, but especially the 100 mile distance. 

100 mile Distance - What Counts for 2023?

All Results must be from between 1/1/2019 and the race date of the chosen event. 

  • Completion of a 50 mile single stage ultra within 15 hours and with a published set of results. (Note if you have finished a 50 mile event within the cut off of that event, but in a time over 15hrs, you may apply to the committee for exception). 
  • Completion of a single stage ultra longer than 50 miles in length.
  • Completion of a Double Iron Distance Triathlon (Run Stage is single stage and over 50 miles in length)
  • Completion of a multi-day race where one individual stage is longer than 50 miles and invividual stage results/ lengths are published. Example: Marathon Des Sables where the long day is greater than 50 miles in length. 
  • Completion of over 50 miles in a timed event up to 12hr 
  • Completion of over 75 miles in a timed event up to 24hr

100 mile Distance - What Doesn't count for 2023?

  • A race that is less than 50 miles in length.
  • Completion of a 50 mile event outside of 15hrs total time (Exceptions apply for significantly more diffiult events at the discretion of the committee).
  • Running the qualifying distance in training only. GPS traces/ Links to Strava, Garmin Connect or Movescount do not count.
  • Running the distance as part of a military exercise where no results are published.
  • Running the qualifying distance in an official race, but not as a single stage effort: Example: Completing 50 miles over a two day event or over two separate runs on the same day.
  • Ironman 
  • Completing over 50 miles in an ultra distance event, but not completing the full event. Example: DNF at the SDW100 at mile 70.
  • Old results. Example: Standard must be achieved between 1/1/2019 and race date, and the entrant offers a result from 2018.

50 mile Distance - What Counts for 2023?

All Results must be from between 1/1/2019 and the race date of the chosen event. 

  • Completion of a marathon (or greater distance) single stage race within the time limits of that event and with a published set of results. 
  • Completion of an Iron Distance Triathlon (Run Stage is single stage and 26.2 miles in length)
  • Completion of a multi-day race where one individual stage is longer than 26.2 miles and invividual stage results/ lengths are published.  
  • Completion of over 26.2 miles in a timed event (includes up to 6hr but NOT more ie. 12hr, 24hr, 48hr or 6 Day+ Races)

50 mile Distance - What Doesn't count for 2023?

  • Running the qualifying distance in training only. GPS traces/ Links to Strava, Garmin Connect or Movescount do not count.
  • Running the distance as part of a military exercise where no results are published.
  • Running the qualifying distance in an official race, but not as a single stage effort.
  • Completing over 26.2 miles in an ultra distance event, but not completing the full event. Example: DNF at the SDW50 at mile 42.
  • Old results. Example: Standard must be achieved between 1/1/2019 and race date, and the entrant offers a result from 2018.

* One caveat here are races which are published to be a certain distance, but are renowned for being short. If a race is advertised as 50 miles by an organiser, it will be counted as a 50 mile race and will be accepted as a qualifier.
