Erwin Park DIY-O 2022

Erwin Park DIY Event

March 12-20, 2022

Erwin Park, McKinney

Return to Erwin

Our next event brings us back to Erwin Park in McKinney.  We had our first Erwin DIY-O, a year ago, during the Big Freeze… and the subsequent thaw.  This year, conditions should be much less harsh.  

For those advanced runners who like a real challenge, we are offering an additional set of maps that will not show the trails. If you want to try something different, test yourself with the BrownNT or GreenNT courses (see details in the Course Setter Notes.)


Do-it-Yourself Format

This event will be “orienteering without the meet” again, like we did at Arbor Hills in the fall.  

The event will begin when the park opens on Saturday, March 12 and extend over 9 days through Sunday, March 20. 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. 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.

N/A — No awards, so no classes.

Event is closed! We hope you enjoyed it!


  1. Click through to the Participation Waiver page. Fill out the online waiver and you’ll get access to print the map for the course(s) you choose.
  2. Arrange for your own “runner accountability.” We recommend telling a friend or family member where you are going and when you plan to finish. Provide them with a map. Or, you may choose to meet another orienteer at the venue and run simultaneously.
  3. Gather your gear and don’t forget to bring your own water and map.
  4. Run the course. Find the ribbons. Enjoy.
  5. Check in with the person you made plans with in step 2.
  6. Let the course setter know if there are any ribbons missing, so he can replace them.
  7. Optional: Post your results to NTOA’s Facebook Group. (Join us!)
  8. Optional: Rinse and repeat! You’re welcome to do any or all courses and come back as often as you like during the period the ribbons are out.

Event fees

We’re not charging event fees for this virtual, self-serve event, but donations are always appreciated! We’re a non-profit organization.
