Course Setters' Notes
By Erin Schirm (Friday & Saturday) and Matej Šebo (Sunday)
Friday Relay at Hidden Lakes/Hidden Valley Park
Course Details: 1.9–2.2 km; roughly 40–60 m of climb
Teams of two, where each person runs two legs. We will put teams together at the event. Please make sure to show up by 6:10 PM, so we can make sure you know your teammate, and go through the exchange and arena before the race starts.
Forest orienteering shoes recommended. No medal studs if possible.
- This is a classic county park with a mix of forest, open land, athletic fields, a large trail network, and a mix of hills.
- The unique feature is a string of lakes that goes through the park. Between these lakes there is a large stream/gully with a mix of earth cliffs, dark green, and passable areas. I will be marking this out-of-bounds for the race, so its clear and no one takes a route choice into an area they can't get out of. Passages will be marked where relevant.
- Generally the map uses ISSOM (http://orienteering.org/resources/mapping/) standard symbols, including trails.
- It's important to note that there are plowed areas that look like trails, or have made it a little harder to notice where the trail goes through. I did not differentiate these beyond rough open, and continue the trails in places where they go through the plowed areas.
Saturday 3-Round Knock-Out
Round 1 will be 4 heats of 7 runners each. The top 2 from each heat, and the next 6 fastest times, will advance to Round 2.
Round 2 will be two heats of 7 runners each. After the heats finish, there will be an open start window for all the people who did not "qualify" for Round 2. The top 2 from each Round 2 heat, and next 2 fastest Round 2 heat times, will advance to Round 3.
Round 3 will be a "final" with 6 runners. After the final finishes, there will be an open start window for all the people who did not "qualify" for Round 3.
Saturday Round-1 Knock-Out at Paso Nogal Park
Course Details: 2.4–2.6 km; roughly 80–90 m of climb
For the first round, the challenge will be to spot the best forking. There will multiple forking options that will be either 42A–43A or 42B–43B. Your job is to choose what you think is the shortest forking, and you need to go only to the controls on the forking you choose. Please note that you can't switch forking halfway through. Once you choose the forking, you're on that forking until the course comes back together. Numbers of the controls will be printed on the map.
There will be a 1 km walk/jog to the Start. Parking will be at Diablo Valley College. You will be able to pick up a walking map at registration to get to the Start at Paso Nogal Park. The Start and Finish are close to each other, and the walk back is the same as the walk there.
Forest orienteering shoes suggested.
- Another classic park with a mix of open land, semi-open land, forested areas, and patches of mixed-green vegetation.
- The park is used for dog walking, so please be aware. Dogs should be on leases, and there is a fenced-in dog park that many people take their dogs to.
- The ground is getting pretty soft with the recent rain.
- There are areas with a bunch of scattered trees that are mapped pretty well, but be aware that there is a variety of vegetation features used to depict what's going on—they will be hard to see at a fast run.
- There are some small trails that have disappeared and others that have popped up. I updated the map as much as possible, but be aware there might be a few new trails not on the map.
- Finally there is an area of the map that you might run by on the courses where there is an end to the map, but the park goes further. This area will be marked out-of-bounds on the map. There will be no visible markings in the terrain, but it should not be much of an issue.
Saturday Rounds 2 and 3 at Diablo Valley College
Course Details: 2.8–3.2 km (best-route distance); roughly 40–60 m of climb
Urban running shoes recommended. However there might be areas that are slippery, so rubber shoes are fine, but medal studs are not permitted.
Round 2: The second round will use butterfly-loop forking, and will have a map flip. The map flip will happen roughly two-thirds through the course. There will be one common control on each side of the map. So when you flip the map, the control you are at last on side one will be the first control on side two of the map, with the rest of the course.
Round 3: The final round will have multiple loops for forking, and will go directly into what I call the maze. In order to better show the maze area, the scale of the map might be blown up, which will be announced at the Start—so be prepared. The nature of the maze is multi-level—in some cases three levels. I have done my best to depict this on the map, however the clue sheet will show which level the control will be on using upper, lower, and middle. Note that this is supposed to be a fun challenge, and the nature of the multi-level area makes it a little harder to make out. So part of this final round is a little bit about using the clue sheet and making your best guess.
- DVC is a classic college campus with grassy areas, a mix of open land and trees, gardens, and a mix of buildings.
- I'm in the process of updating the vegetation, and got the majority of it, but there might be inconsistencies in the vegetation mapping. Please note that anything marked with the dark-green and olive-green-impassable vegetation symbols must not be run through.
- The most interesting part of the campus is its sections of multi-level areas in the buildings. There are a few areas with three levels. I have done my best to depict this using the tunnel symbol and light grey. The tunnel symbol is used to show the lower level, and the grey depicts the upper level. In cases of the third level, it was hard to show on the map, but I did my best. Make sure to check your clue sheet in the races!
Sunday at St. Mary's College
St. Mary's College is a brand new map created by Bob Cooley in October 2018. The map is drafted according to the ISSOM (http://orienteering.org/resources/mapping/) standard, at 1:4,000 scale with 2.5 meter contours.
This small college campus is located just outside of Moraga, and has a few unique qualities that make it excellent Sprint terrain. The center of the campus is almost completely flat, with the terrain sloping sharply upwards around it. The courses are mostly set in this flat central area, so climb should rarely be a factor. The campus has many overhangs, and narrow passageways with sharp changes in direction. Attention to detail is often important to determine which areas are passable, and the shapes of the buildings make it possible to set longer route choices with multiple possible options.
- 8:00– 8:50 Packet pickup
- 9:15– 9:40 Qualification round (Qualifier) with assigned starts
- 11:20–11:35 A-Final with assigned starts
- 12:00 Award Ceremony
- 12:35–13:00 B-Final with assigned starts
- 14:00 B-Final course closes
Both courses are interval-started. The Qualifier will use a 30-second start interval with assigned start times (don't be late for your start!).
The top 8 men and top 6 women in the Qualifier will receive start times in the A-Final. Everyone else will run in the B-Final, which will start after the A-Final is done so that everyone can watch the A-Final.
The A-Final and B-Final will be run on the same course. Both Finals will use a 1-minute start interval, with the start order in reverse order of the results of the Qualifier (that is, fastest runners start last).
The Qualifier and the Finals are National Ranking Events (and thus have 1-hour time limits).
Course Distance Climb Controls Qualifier 2.5 km 20 m 15 Final 2.4 km 30 m 19
The two courses will start from different locations. The call-up lines for both the Qualifier and the Final starts will be visible from the assembly area (Chapel Green), where the Finish is located. The Finish is shared between the Qualifier and the Final.
These courses will both be set to Sprint standards. There will be many changes in direction, with an emphasis on quick map reading and route choice. The expected winning times are in the 12- to 15-minute range for both courses. Due to the short length of the courses, no refreshments will be offered at controls.
Both courses will be printed across two maps. Both maps will be provided to competitors at the Start, facing outwards within a single map case. Competitors will start the course using one map, and after completing the course up until a certain control (#10, for example), will flip over their “double-sided” map and use the other map through to the Finish. In this example, map 1 would depict the course from the Start Triangle to control #10, and map 2 would depict the course from control #10 to the Finish. Control #10 would be shown on both maps. This makes the maps much easier to read, as parts of the Qualifier and Final courses loop back on each other.
A small section of artificial fencing will be used to make a part of the terrain more interesting. This artificial fencing will be clearly marked in the terrain with several lines of chest-high pink streamer tape. On the map, it will be depicted as an impassable fence. Any competitor spotted crossing this barrier, or any other impassable barriers as defined in ISSOM (http://orienteering.org/resources/mapping/) (i.e., buildings, olive green, 50% black/100% green, as well as any walls, fences, or hedges that are mapped as "impassable"), will be immediately disqualified. Marshals will be stationed throughout the courses to ensure fair play.
I would also like to remind all runners to carefully read the map when approaching a control. Remember that not all of the controls you see will be on your course, so remember to check each control code before punching.
