  • Your best 3 performances in the Half Marathon Trail Series will rank you in the series standings!
  • If you want to do fewer events, that’s okay! Series events are open to everyone.
  • If you want to do more events, that’s awesome, because it gives you another chance to improve your score.
  • If you complete any of the Half Marathon Trail Series events, you are automatically entered.
  • Points are awarded based on finish placement.
  • Women’s and men’s placements are scored separately.
  • The 1st place woman and 1st place man in each event score 100 points, 2nd place scores 95, 3rd scores 92, 4th scores 90, 5th 89 and so on. Places 64th and lower score 30 points.
  • In the event of a tie, each runner’s highest point score is used for the tie-breaker. If two runners have identical highest point scores, then the next highest point scores are compared until the tie is broken.  If all scores in rank-order are identical for two or more runners, then the tie is broken according to the size of the competitive field (largest number of runners ranks higher) at the run where the highest score was earned (then second highest, and so on, until the tie is broken.)
  • The top series participants receive special recognition and free entry to a future trail run to be announced.
  • Awards will be presented in the following categories: Open Women, Open Men, Masters Women 40+, Masters Men 40+, Youth Girls 18/under, Youth Boys 18/under
