My son Bevan and I decided to try this new format for an O-event.
Mats Jansson at TrackMe360 makes it possible to orienteer in
breathtaking Sierra environments by staging the event over a month
or two (no permits required). A team can sign up to run (in our
case, walk) the course on any day. Coordinates are emailed the
night before and the map is standard USGS 1:24,000 scale. It’s all
enabled by a GPS tracking device that records where you’ve been
without any user interface to indicate where you are on the
course… At the end of the run, you simply send in the tracking
device to TrackMe360 which is used to verify that you actually
visited the controls (streamers). The tracking device also uses GPS
time to record your time (maybe even split time, although this
doesn’t seem to get posted on the results website).
The control placements are essentially Orange level on a BAOC map.
But coupled with the relative imprecision of a USGS map, a couple of
the controls had some surprising challenges. In particular, since
anything other than forest vegetation is not mapped, route choice
can lead to surprises in the area of Silver Lake (near Kirkwood ski
area). Large granite boulders and cliffs resulted in an unexpected
effort to get to one of the controls. And sometimes waist-high
brush (obviously not on the map) got in the way of taking the most
optimal route to the control.
We chose to do the Long course (27K), which had 8 controls and a
1000 meter climb (optimal). Probably 60-70% is off-trail. We walked
most of it, with a few downhill runs, and a few more slow rock
scrambles. We did not do the optional peak climb because we didn’t
think the additional time would be less than the reduction of 90
minutes from our overall time on the course (if we’d done the
optional climb). Maybe for those of you in better shape, it would
be worth it. In fact we averaged a little less than 3K/hour over the
whole course.
We were pleasantly surprised that two of the controls had some very
interesting route choice options. Again, because of the poor map
quality, there is a little more luck involved than I’d prefer. But
in retrospect, on the two controls that we bobbled due to poor route
choice, a closer inspection of the map would have resulted in a
better approach.
If you decide to do this Mountain-O, be sure to carry a water
filter. We each started with 2 liter CamelBaks, which we finished
by lunch and the 1/2 way point. We then refilled (pumped 4 litres)
from a well marked spring but at a lower than optimal location. The
water was a bit contaminated from previous high altitude cattle
grazing, but we survived. The last third of the course has
plentiful water from streams and lakes.
Bottom line, if you like to hike in the Sierra, then you should try
this O-event. It will help you to sharpen your large scale
navigation skills, and give you plenty of great views.
