General Rules
Please go here for rules covering all events.

Orienteering Rules
Events will be held in 10-year age groups (50-59, 60-69, 70-79, 80-89, 90-99, 100+) with no gender divisions. US Orienteering Federation Rules will be used with exceptions and modifications. The Event Host will provide equipment. For questions call 703-987-9070.

A) The Events

  • A Beginner/Advanced Beginner course of approximately 1 to 2.5 kilometers straight distance.
  • An Advanced course of approximately 3.2 to 5 kilometers straight distance.
  • Only one orienteering course may be entered per person.

B) Equipment

  • The Event Host will supply orienteering maps (1:5,000 or 1:7,500 Map Scale for the Beginner/Advanced Beginner Course and 1: 7,500 or 1:10,000 Map Scale for the Advanced Course), epunches (electronic timing devices), if used, and compasses. Competitors may use their own equipment.
  • GPS units with visual displays are not permitted.
  • Any other equipment may be carried provided it is not used for navigation or communication.
  • There will not be any water available to participants out on the course, so they should plan to carry the volume of water they feel they will need.
  • Control descriptions will be provided in English on both courses and international symbols on the Advanced Course.

C) General

  • This is an individual event.
  • Competitors will be released onto the course in 2 or more minute intervals.

  • Any route is permissible between checkpoints, except private property and out of bounds areas shall not be entered.
  • Obvious following an other competitor is discouraged.
  • There will be no overtime designation (there is no maximum time limit for completing the course). However, for security reasons, every competitor must finish by 3:00 p.m. even if he/she has not finished the course. 

D) Declaring Winners

  • Medals will be awarded and competitors will be ranked according to best times in each age group and course category.
  • In the event that not all controls are visited, winners will be based on the number of sequential controls from the start.
  • Medals will be awarded following the competition.

Which course is for me?


Choose this novice course if you are just beginning to orienteer and have had little or no experience. Before starting you should know:

  • how to interpret map symbols and colors (legend).
  • how to orient the map to North using a compass and/or land features.
  • what are the basic objectives (rules) of orienteering competition.
  • what to do when hopelessly lost (how to use a "safety bearing").

This course is designed to introduce you to, and give you experience in:

  • following land features ("handrails" such as trails, roads and streams)
  • learning to relate the map to features on the ground
  • judging the distance between control locations
  • gaining self-confidence in map reading
