Event Write-Up
By , Event Director
Despite unseasonably warm temperatures, many intrepid orienteers ventured into Calero County Park in search of controls. With great determination, they climbed the steep hill to the Start, which (perhaps conveniently for some) also served as a warm-up. The courses took them along dusty trails and through tall grass as they ascended, descended, and contoured around the many many hills that call Calero home.
As always, this event was made possible by the contributions of many people!
Thanks to Calero County Park and ranger Jesse Baptista for allowing us to use their beautiful space for our event. Orienteering events often introduce people to parks they haven't visited before, and inspire new appreciation for these places.
Course setting is an intensive process that involves hours of planning, multiple field checks, and the placement of dozens of controls. Many thanks to course setter John Richardson for designing eight brand new courses for us to enjoy, and for spending Friday and Saturday setting up most of the controls so that we could open the courses early on Sunday!
Co-event director Stephanie Maclean secured the park permit weeks in advance of the event (Thank you!), ordered the maps from the print shop, and provided guidance on different aspects of event directing.
Set up in the Assembly Area and at the Start went smoothly thanks to Carson HS NJROTC, Josh Munic, Tamara, Ben the Boy Scout, and Ben's grandmother. Hauling all of the start equipment, including several gallons of water, to a remote start location that was 1 km away and 50 m up was no small feat. With the help of many hands, we were able to move all of the gear in one trip and open the starts as soon as the courses were ready.
The stellar Calero registration team of Sarah Williams, Steve Haas, Sheila Cotter, and Chuck Spalding handled pre-registration and on-site registration.
The event was well-attended by beginners, who benefited from Dan Greene’s instruction on orienteering fundamentals. Thanks to Dan for covering beginner clinics all morning!
E-punch was capably handled by the expert team of Jeff Lanam, Phil Lacroute, John Blakken, and Dan Greene, who ensured that everyone had an E-stick, had their results tied to the correct course, and were able to download results. Jeff did the after-event processing of the results, including posting on WinSplits (http://www.obasen.nu/winsplits/online/en/show_event.asp?id=111220) and Attackpoint (https://www.attackpoint.org/eventdetail.jsp/event_60556).
First-time starts volunteer Gordon Bloom managed the large crowds at early starts with ease. (It's always heartening to see people step up to volunteer for the first time! If you've been thinking about signing up for a role, you're in luck, because the next opportunity is only 2 weeks away! Just email event director to sign up.)
With afternoon temperatures peaking in the mid-80s, the control pickup crew of Tac Sugiyama, Rex Winterbottom, Theo Verhoeven, Jake Niebaum, Johan Grobler, Nikolay Chukanov, and Josh Munic rounded up the 45 controls spread across several square kilometers.
Thanks also to Chuck Spalding for setting up the event webpage and volunteer spreadsheet, and for his prompt updates to the event page.
Please let me know if I inadvertently omitted anyone or if other corrections are needed. Hope to see everyone in two weeks at Joe Grant!
Lost and Found
Two items were found at the park after the event:
- A very nice metal clothes hanger (found at the Registration picnic table)
- A Salomon "HydraPak Soft Flask" (500 ml/17 fl oz) hydration flask (found on the course by the control pickup crew)
Additionally, the two items found at the previous Morgan Territory event are still unclaimed:
- A pink/orange/gold pair of goodr sunglasses with "Arches National Park" on the arm
- A light-blue Danskin Now quarter-zip sweater, semi-fitted, size XL
If any of these items belong to you, please let me know! (If these items are not claimed by April 12, they will be donated to charity.)
Course Setter's Comments
By John Richardson
Many thanks also to Kat for stepping in to cover for Steph as Event Director. The heat brought a number of unexpected challenges on the day, and Kat did an amazing job handling everything smoothly.
Apologies to the Silver runners who encountered steeper/slipperier slopes or more PO than intended. The park is much more runnable earlier in the year, and if the calendar allows, I hope we can shift to an earlier slot next time. And perhaps make Silver more of a "sprint" — so we can still have technical orienteering without longer "route choice" legs that inevitably require a lot of climbing or contouring.
Thanks again to all the volunteers who made the event possible, and we hope to see you all at our next event, Joe Grant, where we'll also be holding the BAOC Annual General Meeting.

Also see control-by-control timing in the WinSplits results (http://www.obasen.nu/winsplits/online/en/show_event.asp?id=111220) and on Attackpoint (https://www.attackpoint.org/eventdetail.jsp/event_60556).
You can see the event map with the actual routes traveled by participants, and draw your own route for comparison, in RouteGadget for this event (http://baoc.org/gadget/cgi/reitti.cgi?act=map&id=576). (Use of RouteGadget is explained here.)
- In RouteGadget, you can enter your route manually or upload a GPS recording and adjust to fit our map. The following tips apply to the GPS method.
- RouteGadget Tip #1: After selecting your GPX file, make sure to adjust the time offset between starting your watch at the Start line and leaving the Start Triangle. The offset can have a significant impact on your route accuracy. For most local events, you should set the offset to 0 as we start from the triangle (assuming you started your watch exactly when you started).
- RouteGadget Tip #2: After uploading your GPS track to RouteGadget, you can create additional blue adjustment points by right-clicking your track. You can use these points to better align your route with the map, for example, along trails. You can delete extra adjustment points by right-clicking them.
- Comments from the E-punch Director:
- Thanks to Event Director Kat Lan and Course Setter John Richardson for a challenging event in this hilly park.
The unseasonably hot weather was an additional challenge, but many made the attempt.
Thanks to all the volunteers, especially those who worked with the many beginners. I want to thank my E-punch crew: Phil Lacroute, John Blakken, and Dan Greene. - – Jeff Lanam, E-punch Director
