Event #2 of 6 in the BAOC 2023 Summer Series

Date: (Sun.) Jun. 11, 2023
Location: Oakland, CA
Event Director: - 510.407.1876
Course Setter: George Minarik
Type: C; This is the second event of the 2023 Summer Series. Beginners are welcome!

Please note that fees and time limits apply. Events are typically not canceled due to bad weather.

Southbound I-680 Will Be Closed in Pleasanton on Sunday

According to this CalTrans website (, southbound I-680 will be closed in the Pleasanton area on Sunday. That's not a likely route to the South Bay after the event, except for people who detest I-880, but you have been warned. 😉

This event will be the second of six events in the 2023 Summer Series. However, we want to emphasize that everyone is welcome to come out and do one (or more) of the courses, regardless of whether or not you attended the previous Summer Series event, or plan to attend later events.

Beginners new to orienteering are encouraged to attend​—​the navigational difficulty is significantly eased by the nature of the campus, so anyone should be able to complete the beginner course.

We will offer three courses: one for beginners, and two longer courses for the Summer Series. Advanced orienteers should not be put off by the “easier” navigation​​—​​it will give you an opportunity to practice making faster decisions, and running faster, than your competition.

The assembly area will be next to Haas Pavilion, which is next to the main road through the campus. However, please do not park along that road​—​see below for parking details.

We look forward to seeing everyone at what should be a fun event!


The standard BAOC event schedule will be followed:

    9:00 AM – 11:59 AM: Registration open
    9:30 AM – 10:30 AM: Beginner clinic instruction (free)
  10:00 AM – 12:30 PM: Starts are open for all courses
                    2:00 PM: Courses close, checkpoint control pick-up begins
Note: At on-site registration, all juniors must be accompanied by parents or legal guardians, or bring with them a waiver signed by their parent or legal guardian (the registration form is available here [PDF/12KB]).

Note that you can register and start on the courses anytime during the open times above. Thus, for example, you do not need to be “punctual” at 9:00 (but you can if you want, but please don’t show up earlier and expect to be served).

Beginner clinics are 15–20 minute, repeating sessions that introduce the sport of orienteering, and provide enough instruction to be able to complete the Beginner (White) course.

Note that you must return to the Finish by 2:00 PM, and then go to the download tent, even if you have not finished your course. Please do not leave without checking in! If there are unaccounted people after 2:00, we must initiate a search for them.

  • Members of other orienteering clubs can pay the “member” fee. (We hope your club does the same for our members. 🙂)

More information about event pricing is available in the club FAQ. All the prices are also shown on the standard entry form (PDF/12KB), which you can print and fill out in advance to save some time at the event. (You will need one entry form for each group of people going on a course together.)

Online registration has closed, but you can still register at the event.

  • Do not register for this event if you have registered for the Summer Series Discount Package (which is available only to club members).
  • Online registration is not required​—​you can register at the event. Individuals might want to register in advance to simplify check-in at the event.
  • Online registration is available only to individuals, not to groups (i.e., sharing a single E-stick). Groups must register at the event.
  • Compass rental cannot be arranged during online registration, but you can register online and rent a compass at the event.
  • E-punch fingerstick rental can be arranged during online registration.
  • You can see who is registered here ( (but keep in mind that others will register at the event and through the Summer Series Discount Package).

What to Bring

Comfortable outdoors attire and walking shoes are fine for those who will walk their course.

For runners, any comfortable running shoes (without metal spikes) are appropriate. Courses will include lots of pavement and concrete, and some off-trail legs.

A compass is not necessary, but can be helpful. We have compasses available for a $1 rental fee.

We time the courses with the SPORTident system, so a SPORTident fingerstick is required for each team​—​they rent for $5. (Use of the “E-punch” system is easy. You can learn how at the event, or read about it here.)

Note: Please do not bring a dog to the event. They are not permitted on the campus.

Venue Facilities

There are restrooms near the assembly area.


Here are the course details (which were revised on June 7th):

    Course            Length   Climb   Controls
    Beginner/Yellow   1.9 km    25 m      19  
    Short             3.6 km    40 m      16  
    Long              5.4 km    90 m      23

Note: The course lengths are measured “along the preferred route” (i.e., as determined by the Course Setter), not the straight-line distances between controls.

The Short and Long courses will be the ranking courses for the respective Summer Series.

Important Note:

This event will observe Sprint rules for all the courses, which means there are strict interpretations of some of the symbols on the map. In particular, some symbols indicate features that must not be crossed (i.e., even if it’s physically possible to cross them), and areas that are out of bounds (i.e., must not be entered). If you don’t know about those symbols, be sure to ask somebody before going to the Start​—​or download this file (1MB PDF), which contains a map legend that probably applies to the Berkeley map (note all the “forbidden to cross” symbols!).
In addition to being against orienteering rules, violating those restrictions could jeopardize our ability to hold events on the campus in the future!

Be sure to read the Course Setter’s Notes for more information.

Course Setter’s Notes

By George Minarik

The map scale is 1:3000; the contour interval is 2.5 m. The mapping standard is an old version of ISSOM (284KB PDF) (International Specification for Sprint Orienteering Maps), not the latest version (ISSprOM 2019-2 (1.2MB PDF)). There is no legend on the maps. If you need a legend, pick one up at registration. (This file (1MB PDF) contains a map legend that probably applies to the Berkeley map. Note all the “forbidden to cross” symbols!)

The Start is a 5-minute walk from the registration area.

The Start Triangle is located 30 meters from the start line. You must go to the Start Triangle, but there is nothing to punch there.

Note: There is a short tunnel to run through on the way from the Start to the Start Triangle. The tunnel clearance is 5 ft 11 in (180 cm). If you are six feet or taller you will need to duck.

The Beginner/Yellow course maps will be handed out at registration. The Short and Long course maps will be distributed upon starting in the normal way.

Control descriptions for the Yellow/Beginner course are on the map; loose descriptions can be picked up at registration when you get your map.

There are control descriptions on the maps for the Short and Long courses, but the font is quite small. So, competitors on these courses should pick up a loose copy that has a more readable font. The loose control descriptions for the Short and Long courses will be available at the Start.

Upon turning over your map, your first impression will be that there’s a clutter of circles, lines, and numbers! Upon leaving each control, the direction to the next control might not be immediately evident. Be careful! As always, check the control codes, and punch the controls in order.

There is a Eucalyptus tree-trimming and removal program taking place on campus. The program might move from day to day, so the affected areas might or might not be marked out of bounds on the map with red slashes. There might or might not be signs or streamers on the ground. If you encounter one of these areas, go around!

Leona Creek bisects the campus from north to south. The creek is marked as out of bounds. Luckily there are seven bridges you can use to cross the creek​—​you must cross the creek on a bridge.

Running through planted gardens is strictly prohibited. Most of these areas are marked on the map by the dark green out-of-bounds color. The standard olive-green color is also used to indicate out-of-bounds areas.

There are many outdoor “canopy” corridors on the campus (which are mapped as light gray). Please run/walk cautiously through these corridors to avoid collisions other people. Entering any building (dark gray) is prohibited while on a course.

Request for Help

As always, this event can’t happen without volunteers.

It's very easy to help, and it helps us have an event for all of us to enjoy. Of course, you get to do your course, too!

Not sure what to help with? Just want to help with something? Just contact me, and I can help you find a helpful role.

Please contact me if you can help.
