- Official Result: a weblink to the results of your completion of an official trail race, 50km or longer. You must be an official finisher and complete the course within advertised cut off time. This means, for example, you cannot submit a result showing you made it 55km into a 100km race.
- Unofficial Result: a weblink (eg strava link) of the completion of a self-timed run, 50km or longer. The 50km must be completed within a 10-hour time period and a clean GPX recorded.
