This is the first event in the BAOC 2017 Summer Series.


We are less than a month away from the start of the BAOC 2017 Summer Series. So please note your calendars, and be sure to join us for the first event at the Main Post in the beautiful Presidio of San Francisco on Saturday, July 8th. Starts will open at 10 AM as usual.

The event will feature a single course composed of three loops. Everyone runs the same loops, in the same order. There are no beginner courses. However, since this is a highly urban and compact area, the course is suitable for anyone with some orienteering experience at Yellow (advanced beginner) level or above.

Each loop will be printed on a separate map. At the end of the first loop, you will drop your map in the box provided at the transition control (be sure to punch that control), and pick up the second map from a clearly marked map tray nearby. Likewise, at the end of the second loop. The end of the third loop is the Finish.

The first loop is approximately 2.4 km (straight-line distance), the second loop is 2.2 km, and the third loop is 1.2 km. Hence, all three loops together make a course of approximately 5.8 km (straight-line distance).

However, if anyone wants a shorter challenge, the ends of first and second loops are fairly close (~200 meters) to the Finish control. So you are welcome to finish after one or two loops if that is the distance you are looking for (be sure to punch the control at the end of your final loop before going to the Finish). Whether you are doing one, two, or three loops, please ensure that the Finish control is the last control you punch. And please be sure to download after you finish.

Points for the Summer Series will be awarded to everyone who completes the three-loop course. The exact system of scoring will be announced at least a day before this event.

There is very little climb​—​less than 100 meters for the entire three loops. There will be about 42 controls in total, roughly evenly distributed between the three loops. If you are planning to do more than one loop, you should ensure you have a high-capacity E-stick (available to rent or exchange at Registration).

There is not too much vegetation to negotiate, so short pants could be appropriate. The biggest hazard by far is road traffic: The courses necessarily cross several active roads. Please use extreme caution when crossing all roads. You can expect a lot of other park users, so please be mindful when using sidewalks, etc.

As a requirement for our permit, we are not allowed to approach certain buildings. These areas are clearly marked on the map as either out of bounds, or marked in the usual drab-green color indicating "restricted area". Please respect these limitations, and keep us within the restrictions of our permit for using this outstanding area.

We could use a few additional volunteers for control pick-up and some other duties. Please contact if you can volunteer.

Thanks!
