Instructions on using MapRun (Thanks to Bill Cusworth of BAOC for letting us use his write-up)
MapRun official website page


Upon registering and accepting the waiver, you will be emailed a link to the map file. All of the maps are together in one PDF file. The PIN that you need for the MapRun app is printed on each map.


Be sure to select and load the event in the app before you arrive. Once you are there, you will be able to run the course if it is already loaded, but will not be able to download the course if you have a bad connection.
Similarly, make sure that your results upload after you finish.
Because of Map and GPS inaccuracy, it is important that you use the printed map for navigation. The circles on the map in the app may not be perfectly accurate, but it will punch properly when you are in the printed circle.

The maps for the Green and Red courses do not contain control numbers, but it doesn't necessarily matter because it is a Do-It-Yourself event.


This event is in a wash that is generally dry, but involves creek crossings that can be dangerous when there is water. It is recommended that you wait at least a week after any significant rains. Do not continue your course if the conditions are unsafe. 

Please choose a course that is suitable for your experience level. Bring water with you. There is no water placed on the course. If you go alone, please make sure someone knows when to expect you home and has a copy of the map.

Registration and Pricing

Please fill out this form to register and accept the waiver. Links to the maps will be emailed to you after registering.

There is no charge for this event.
