Course Setter’s Notes
By George Minarik
BAOC welcomes you back to Tilden Park after a several-year hiatus. We offer the five courses described below.
Since this park is quite steep, we have done our best to alleviate the climb. Each course has about a 5-percent climb along the best route, and the lengths are on the short side.
As you will see, the Park District is working on some very nice improvements to the Lake Anza parking lot. Thus, there will be a large red-hatched splotch on your map indicating a fenced out-of-bounds area.
The ubiquitous poison oak is less potent during the fall, but you should know how to identify and avoid it (red leaves or bare sticks—both should be avoided). Washing soon after having contact is strongly recommended.
Here are the details of the courses:
Course Length Climb Controls Difficulty White 1.2 km 65 m 10 Beginners Yellow 1.4 km 80 m 10 Advanced Beginners Orange 3.5 km 155 m 11 Intermediate Brown 2.5 km 120 m 9 Advanced Green 3.6 km 170 m 14 Advanced
- Beginners should be aware that the distances shown are the cumulative straight-line distances between controls. Your actual distance will be longer. The climb numbers represent the amount of ascending that would be done on the "optimum route" (in the Course Setter’s opinion), without regard for any descending.
There are course-specific comments below.
The map has held up well over the years, but you may encounter some unmapped small trails and some vegetation changes.
The maps do not have the legend printed on them. Loose copies of the legend will be available on request at Registration and at each Start location.
Control descriptions are printed on the maps. If you need an additional, loose control description, pick one up at the Start.
As mentioned above, there is a large red-hatched splotch on the map indicating a fenced out-of-bounds area at the Lake Anza parking lot.
Special Notes for the White and Yellow Courses
The White and Yellow courses have a map scale of 1:5000, with 5-meter contour interval.
The Start and Finish areas will be near Registration in the Orchard Picnic Area. This picnic area is a 5-minute walk from parking. Follow the small red flags.
Special Notes for the Orange, Brown, and Green Courses
The Orange, Brown, and Green courses have a map scale of 1:7500, with 5 m contour interval.
There is a 20-minute walk to the Start, with 40 meters of steep climb. Follow the orange streamers from the Lake Anza overflow parking lot.
For those who have preregistered, there is no need to visit Registration in the Orchard Picnic Area (except if you need to make a change). Unregistered orienteers must first visit Registration, which is a 5-minute walk from the Lake Anza overflow Lot (follow the small red flags).
The hills are steep, dry, and slippery. It is recommended to wear the most aggressive spiked or cleated shoes you own.
Bring your own water or drinks, as there will be none at the Start or on the course.
The courses will twice cross Wildcat Canyon Road, the busy and winding main road of the park. Cross very carefully, yielding to traffic. Running along this road is dangerous and not allowed at this event.
