The start is in the upper part of the park and the finish is in the lower part of the park. It is recommended that you park in the lower park area near the finish because there is limited parking at the top. This also has the advantage of not having to walk up the hill, 0.75 km and 55 m climb, after running your course. Please take the trail to hike between the start and finish and do not walk on the road.

There are no expert level courses being offered but we have added a Long Orange for those interested in a longer trail run.


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.

Safety Information

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. There are some drinking fountains but mainly in the lower park. On the orange courses there are some steep slippery trails so be careful on them. If you go alone, please make sure someone knows when to expect you home and has a copy of the map.
