2019-04-06, Spring #1, 80 m Classic
Carolina North Forest - East

Island Creative Time
The family website of Kelly and Patrick Sears

It was nice cool day. Perfect for running. We had eight participants from three families. All were runners.

The course.

We provided our usual five courses ranked by the number of foxes to find. As usual, the first event of the season is slightly shorter. The top two courses were the green course (4 foxes, 2.4 km) and the red course (5 foxes, 2.7 km). The distances listed are straight-line distances, so participants will be running a fair bit longer distance on each course. The longest distance across the course area was 1.7 km. Radial exclusions zones around controls was 300 m.

To successfully complete a course, participants must punch the start, at least one fox on that course, the homing beacon, and the finish. These are the same rules used in the championship events.

CTS-Evpro - the new electronic course timing system.

This was one of the most exciting developments for us as event director and planner. After two years in development, we finally have a working system. We thought it would change many aspects of the event, but we weren't certain. Wow! It changed everything. With the automatic timing, it truly felt like a real event.

It was super fun to have people get back and crowd around the laptop to see their times. The different courses had more meaning. We could put the start up by the main trail with no worries. The biggest change may have been at the start where the timing box had more use than ever. Finally, it reduced the load on Kelly. When Patrick was on course with the class, Kelly would be trying to keep track of precise start and finish times while doing all the other base table work. This time, it all happened by itself.

There are still a few rough spots in the system. A few controls didn't get registered. The time of day is reported rather than time from start. All this should be easy to fix in the code. But it was so much better than the punch cards!

Participant Activities

John and his father Mike arrived first. It was their first time trying ARDF. The learned all about orienteering, 80 m directional receivers, and the timing for ARDF classic events. They decided that they wanted to try it on their own and pretty soon they were on course. Even with this being their first time ever, they found four foxes. Excellent!

Morgan and Owen, and their parents Scott and Sarah arrived while the class was going on. They grabbed their equipment and came over for a quick refresher. Mostly they got to learn about the new electronic course timing system and how classic events are different from the foxoring they had tried last year. They took two RFID cards and so got listed as two groups. Mostly though, they stuck together and found all five red course foxes. Fantastic!

Emmett and James arrived some time before noon. After a quick refresher they were off on the red course. They also found all five foxes. Super!

Back at the finish, we had several students run in. Having that RFID card on the arm and that finish box waiting to be punched makes it an exciting run down the shoot with everyone cheering.

Results summary

For the first time, most of the results are generated by the electronic course timing system, "cts-evpro". Unless someone asks to be put on a different course or have something adjusted, the results are directly from cts-evpro.

The cts-evpro find order and time for each control can be found here.

#participants (school, grade)findstime

Participants are first listed by course. Then within a course, by number of foxes found and then by time on course. The # column gives the results placement for that course. The finds column notes the controls found: foxes 1 through 5 and H for the homing beacon. Fox numbers in parentheses were not on the chosen course. The time column is the time on course. Students are listed with their school and grade. We use the following schools abbreviations: PMS Phillips MS, SMS Smith MS, McDMS McDougle MS, CMS Culbreth MS, CHHS Chapel Hill HS, ECHHS East Chapel Hill HS, CaHS Carrboro HS, f family or guest friend, es elementary school, s chccs student (no school info). t teachers and staff members.

Thank you to all our helpers.

Pictures are generally listed in chronological order trying to keep groups together. If you took any pictures during the event, we would love to post them. If you would like that, email us your pictures.

Pre-run briefings.

Mike, Patrick, John. Talking about orienteering maps, contour lines, colors used for vegetation, boulders. All the ways we keep track of our position.

Morgan, Owen, Scott. Pre-run discussion. Probably how to divide up search tasks.

Patrick, Owen, Morgan (in back), Sarah, Scott. From the direction I'm pointing, I think I'm showing the hawk nest that was in a tree just 10 m behind our base area.

Emmett, Patrick, James. Reviewing the two gain patterns of the receiver antenna.

Finishing runs.

A few pictures from our setup.

Kelly. Our base area. The big box on the table is protecting the download laptop for the RFID cards.

Our class area. There is the demo control in the foreground at left. The string holds some notices: the fox timing and sounds at left; the schedule and transmitter frequencies at right.

The start. It is just off the main trail going into CNF. Under the start sign, there is the starter timing description. Under that on the tree, there is the RFID start box and a small orienteering flag. At the base of the tree, sticking out to the right, there is the starter timing box.

CTS Evpro Results.

Back to results summay.

The cts-evpro results are listed here mostly as they appeared during the event. We had a few miss-reads and added foxes for those in the correct order. Those are the ones with missing times. ToC is the time on course. The finds are listed as "control number/fox".

Red course.
