Harry Moss DIY-O

Hall-O-ween with Harry “DIY event”

Oct. 17-25, 2020
Harry S. Moss Park & Preserve, Dallas

Booooo! This event is now over.

The second orienteering event of our season will bring us back to old haunts! Harry Moss Park was one of our most popular venues but has not been used for meets the last two seasons.  After flooding and severe storm damage, the park was closed. But now it has come back to life.  Who knows what strange new features may lurk in these woods? 

Do-it-Yourself Format

This year’s events are different from previous season’s meets because of the pandemic. It is orienteering without the meet. We are implementing a new “Do It Yourself”-style event this fall. The new format will follow state and local regulations, adhere to guidance from Orienteering USA, our sport’s national governing body, and hopefully, protect the health of participants and organizers. We will encourage distancing by extending the duration of the event and eliminating the need for anyone to touch equipment that is used by other runners.  

The event will begin when the park opens on Saturday, Oct. 17, and extend over  9 days through Sunday, Oct. 25. You can choose any day and time you want to run. Think of it as a training event, or a permanent course that only lasts nine days. There will be no onsite organizational presence: no registration tent, no lines, no cost, no punching, no scorecards, no scoring, no DQ’s, no awards. Just orienteering fun. Bring your own water and gear. Controls will just be colorful ribbons hung in the terrain.  

There will be NO BEGINNER (AKA WHITE) COURSE. There are several reasons for this:

  1. Beginners are more likely to get lost and we won’t be there to find them.
  2. Courses will be active for several days in a popular public park. Beginner controls must be easy to find, so they’re hung in obvious locations on well traveled trails, and therefore most likely to disappear over a number of days. Advanced controls can be hung off-trail in less frequented places. 
  3. Beginners tend to run in groups. Groups aren’t socially distant.
  4. We don’t encourage groups to travel to our events on buses at this time. 
  5. We will not have the usual training session for beginners that we have at most meets.

Beginners can participate by running on the ‘yellow’ course with a more experienced runner (ideally a family member or leader) while following safety precautions.
