Important Notes for this event

We recommend that you download the app and the course prior to leaving for the site. That way you know that everything is working.
Because of Map and GPS inaccuracy, you should use the printed map for navigation. The control circles in the app may not be centered correctly on the map, but the app will punch in the correct place relative to the printed map.



We recommend that you bring water with you. There is no water placed on the course, although you may run into park water fountains.
If you go alone, please make sure someone knows when to expect you home and has a copy of the map.


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.
