Course Setter: Deron van Hoff
Type: C; Sprint courses at the Main Post Parade Ground on SATURDAY
This is a last chance to tune up for the upcoming U.S. Sprint Championships at the Tahoe 2021 event. Also, this is a good introduction to orienteering if you are a beginner.
We will return to the Main Post Parade Ground for another set of Sprint-style courses on our ISSOM map produced by Matej Sebo in 2016. Three courses are on offer, of approximately Yellow, Green, and Blue length for a Sprint event.
This event will be suitable for beginners. Orienteers of all abilities are welcome and encouraged to attend.
Note: If you are coming with a group of five or more people, please tell the so we can be sure to have enough maps.
We will be following the San Francisco health ordinance guidelines on the day of the event. That generally means that we can hold the event without social distancing and wearing masks. Nevertheless, we should all be cognizant of the ongoing risk of contracting COVID-19, even for those who have been fully vaccinated. Please stay home if you are feeling unwell in any way. If you are not vaccinated, we ask that you wear a mask while you are in the assembly area, including at the Start and the Finish.
Also, no food or water will be provided at the assembly area, and no water will be available on the courses. Please bring what you need.
Note that the event is on Saturday.
- 9:00 AM – 11:59 AM: Registration is open
- 9:30 AM – 10:30 AM: Beginners' clinic instruction (free)
- 10:00 AM – 12:30 PM: Starts are open
- 2:00 PM: Courses close, checkpoint control pick-up begins
At 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/90KB)).
Note that you can register and start on courses anytime during the open periods 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).
Beginners' clinics are short, repeating sessions that introduce the sport of orienteering, and provide enough instruction to be able to complete a beginner course.
Please note that everyone must return to the Finish by 2:00 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, stick around and socialize with other participants!
The following fees apply at this event:
- $3 for each junior (age 8 through 20) on the beginner (Yellow) course
- $8 for each adult on the beginner (Yellow) course
- $5 for each junior on an advanced (Green or Blue) course

- $5 for an electronic fingerstick rental (if you don't own one; you'll need one to complete the course)
- $15 for the lowest-cost individual one-year BAOC membership (optional)
- We are able to accept payment only by cash or check—no credit cards or electronic payments.
- There is no charge for children under age 8 with a parent, guardian, or youth-group leader.
- There is no charge for a second (or more) course, except the difference must be paid if a later course has a higher fee than the first course.
More information about event pricing is available in the club FAQ. All the prices are also shown on the standard entry form (PDF/90KB), 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.)
Unfortunately, many of the eateries and restrooms are closed due to the economic effects of COVID-19. Fortunately, the Presidio has set up multiple portable toilets for public use. Six portable toilets are available at the assembly area. They were well maintained when I visited, although the disinfectant and soap dispensers were empty at the washing stations.
The Presidio Trust also wants me to make everyone aware that they have seen an uptick in car break-ins—smash and grabs. You should not leave anything visible in your car, and you should be careful about what you are storing in your trunk or glove compartment.
What to Bring
For beginners, comfortable outdoors attire is fine, but you should wear sturdy running or hiking shoes.
The Sprint courses will involve a lot of running on streets, sidewalks, and trails, so running shoes might be appropriate. However, there will also be some off-trail travel for which you might want cleated shoes. You will want long pants and/or gaiters.
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 each entry/team needs to have a SPORTident fingerstick. If you don't have your own, you can rent one at registration for $5. (Use of the "E-punch" system is easy. You can learn how at the event, or read about it here.)
All starts and finishes are at the assembly area.
Here are the details of the courses:
Course Length Climb Controls Yellow 1.9 km 20 m 12 Green 2.7 km 25 m 14 Blue 4.4 km 60 m 22
Note: Unlike “forest” courses, the course lengths above are the shortest possible while going around impassable objects (i.e., per IOF standards for Sprint courses). As usual, 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.
All the controls on the Green and Blue courses are unique—that is, there are no controls shared between the two courses. So, you might want to do both courses.
The Yellow course uses controls that are on both Blue and Green, but in a different order than on those courses. Beginners are encouraged to try the Yellow course first (although it is difficult to get truly lost, so you could start with Green). Feel free to run one, two, or all three courses for your entry fee as long as you arrive early enough to start your last course before starts close and complete by the course closing time. (Note: If you start with the Yellow course and then run either Green or Blue, you must pay the fee difference.)
Here are some other important notes about the courses:
- Impassable features: We need to be good neighbors to the residents of the Presidio, so it is important to follow the rules regarding not crossing “impassable” features.
- Those are features shown on the map as not allowed to be crossed even though some of these are physically possible to cross. This snip of the map legend shows the symbols that you are not allowed to cross.
- Unfortunately, there are many shades of green on the map—the darkest green (usually landscaping) and olive green (private property) are “impassable”.
- Vegetation: Most of the time you will be on pavement and grass. However, there are legs on Green and Blue that you may have wished you had worn long pants or gaiters to take the straightest route. You shouldn’t encounter poison oak unless you decide to take a route through the fight, in which case it is definitely present in its red-leafed form.
- Traffic: There is a ton of traffic, with multiple legs crossing streets. There are also many crosswalks, some with stop signs and some without. Please make sure you stay safe and yield to traffic.
Request for Volunteers
Please tell if you are willing to help for an hour or two during the event. We will need help with set up, beginner clinics, starts, finishes, and tear down.
In particular, has asked for help with E-punch set up, handling entries, and tear down.
Even if you don't have time to volunteer, we hope you decide to come out and run a course.
