Note: The event is shown as "pending park approval" because we have not yet actually received the permit. However, we fully expect it will be issued.


This event is part of the California Orienteering Week (COW), and is associated with the BAOC O in the Oaks 2017 National Event.

Beginners Are Welcome

Even though a lot of attention is being given to the competitive aspect of this event, beginners are still welcome to participate. So, please do not be deterred by all the hubbub about the competition.

In particular, please note that this is a rare opportunity to experience Precision Orienteering (https://en.wikipedia.org/wiki/Trail_orienteering), which is very different than "normal" orienteering. PreO is more mental, and less physical, than point-to-point orienteering​—​the objective is accuracy, not speed.

Please note that everyone on the Sprint course must return to the Finish by 7:00 PM, and check in at E-punch, even if you don't complete your course. We need to account for all participants, because otherwise we must organize a search party for you.

After you finish, enjoy free snacks and refreshments, and socialize with other participants!

Location in the Park

The Assembly Area will be at the Redwood Glen picnic area, close to Skyline Blvd. There is some parking in a dirt siding on Skyline Blvd not far from the Redwood Glen picnic area (see below).

The picnic area has benches and tables. There is a restroom nearby, but the closest water fountains are a bit more of a hike.

Courses

PreO

The Course Setter's Notes for this event are here. A general description of PreO is available here.

Notes:

Sprint Course

There will be only one course. The (straight-line) distance is about 2.5 km, with 115 m climb, and 20 checkpoints. The difficulty will be Yellow-ish to Brown-ish, because it's a "forest Sprint".

Starts will be in the parking area at the edge of the forest. If you don't see Rex Winterbottom in a lawn chair there, check for a blue-green Ford Focus wagon where he will be sitting if it's raining. Then you get checked in, go find the Start unit, punch, and go.

The Finish is by the picnic site. Walk back to the Start (or Rex's car) to download your results.

Course Notes:

Please stay after to help with checkpoint pick-up, beginning at 7:00.

Request for Volunteers

We need some people to run the two timed controls for the PreO event. Please contact if you can help.

Driving Directions

From Highway 13 (Warren Freeway) in Oakland, follow the direction signs for Chabot Space and Science Center, past the Roberts Regional Recreation Area, to the Orchard Trail trailhead. Specifically: From Highway 13 take the Joaquin Miller Road exit and head east, uphill about 1.2 miles to the stoplight at Skyline Blvd. Turn left and continue on Skyline Blvd about 1.1 miles to the trailhead. (The approximate location is 37.815367,-122.178843.)

Park in the dirt along Skyline Boulevard between the entrances to Roberts Recreation Area and Chabot Space and Science Center. After that area is full, there is more space at points along the southwest side (left side while heading northwest) of Skyline Blvd past the trailhead, There is also an actual, free, parking lot, marked "Redwood Bowl Staging Area", about a quarter of a mile northwest of the trailhead (on the right while heading northwest). From there, competitors must walk back to the trailhead along Skyline Blvd​—​don't go into the park earlier, because that is the competition area.

There's a map here that shows the location of the event.

Public Transit

Take BART to the Fruitvale station, then take the AC Transit 339 bus to Chabot Space & Science Center. From the bus stop it’s about a 1/4-mile walk back on Skyline to where the parking is (i.e., the bus passed it on the way to your stop). You must walk along Skyline Blvd​—​don't go into the park earlier, because that is the competition area.
