I’ve always considered myself a good course setter. I never thought I might end up designing a
course that might be in the running for course of the year on World of O
though. Particularly not this year. And yet that’s what happened when I designed
a training course for a friend of mine visiting from Belgium, Yannick Michiels,
on Ottawa’s fabled map the Barrens. I
was looking through some of the courses being put forward during the nomination
period and discovered, to my surprise, that my training course from a month
previous had been nominated.
When it came time to vote 80+ courses had been
nominated. You could vote for your top 5. I had a serious look at the set of courses
and, being as honest as I could, placed mine in 3rd. It helps of course that I was working in
awesome terrain but I knew, based on the fact that the course already had
something like 800 views on WorldofO, that my course actually some merit.

My course ended up finishing
8th. I guess that makes me a
better course setter than orienteer (FootO World Ranking is 309th)! Regardless I think the result is super
cool. Here’s some insight into my course
setting process (you can find the entire course with Yannick's route here):
The Barrens is an amazing
area for technical middle distance orienteering but the layout of its abundant
lakes also allow for great challenging longer route choice legs. Yannick had asked me for some middle distance
type training lasting around an hour in length.
Perfect.
I’ve raced and trained on the
Barrens a good half a dozen times in since its debut at the Canadian Champs in
2010 so I know the area pretty well – something that important when course
setting for training where there won’t be anything at the controls. I felt comfortable in being able to pick out
which features would be obvious enough to use as control circles just by
looking at the map and I knew which areas were most interesting.
That’s the ground work. There’s only one real access road so that
partially takes care of the start and finish variable. I chose the same start location as for the
Ottawa O-Fest 2011 long – it’s easily accessible from the road and provides a
good bit of interesting technical orienteering right from the start. For training the finish generally goes right
by the start – in this case I had no reason not to so that’s what I did.
Given the terrain I split
legs into technical and route choice categories (with transport legs to get
from one section of the course to another as needed) before even starting
course setting.
I wanted to start the course
off with some short legs to get Yannick into the unique terrain. At that point a route choice presented
itself. The route choice isn’t extreme
but the straight route that Yannick took (probably fastest) is still somewhat
technical. The terrain around 4 opens up
a bit so I can take the opportunity to set some slightly longer technical legs
where it becomes tempting to go straight and speed up bit. Dangerous though. While tempting that is risking disaster in
this terrain where it’s easy to get pushed around by the forest, end up in the
wrong clearing, and spend a long time re-orienting.
The next section of terrain
shown below is among my favourite anywhere and certainly on the Barrens. It’s fast and the features are very well
defined. With a little bit of care you
can spike controls in there at full speed.
I knew from the start that I wanted to take my course in here.
The trick here was to set a
few short legs with the controls tucked on the far side of features. I set legs 8 and 9 such that there were one
or two larger features in the middle of the leg but lots of detail in the area
that could be simplified out. Change in
direction was also important and I’ve set control 8 the way I did so that you
come around the cliff to find it but have to go around another corner to get to
9 – you can’t just leave directly on a compass bearing.
Leg 10 is mostly a transport
leg – it’s tricky but it doesn’t emphasize route choice or technical difficulty
in any particular way. I tried in this
case to provide some route choice where you can go straight without too much
difficulty but you have to navigate carefully or you can head left to the long strip
of field heading north west in the direction of the control and then run along
then either left around the large marsh before the control at full speed along
the clearings or stay right for a shorter but slower entrance. I’m not sure it worked – I think straight was
easily the faster choice.
With controls 11, 12, and the
first half of 13, the primary purpose of the legs is to emphasize a unique
aspect of the terrain. The orienteering
in this section is all about weaving through the terrain from open spot to open
spot, around the lakes, and some of the hills and cliffs – micro route choice can
make a big difference here!
Legs 14 through 16 are quite
technical but their primary goal is to set up the first real route choice of
the course.
Going left I see 2 options
for the first half and 2 options for the second half for a total of 4 options
that way. I see another two fairly equivalent
options on the right. I haven’t run this
particular leg and have no idea which would be the fastest. What would you do?
The next few legs are more
transport legs (again difficult in their own right) to get to the more open
east side of the map and to set up the next and final route choice. In hindsight, I could have made one of those
much better.
Here is leg 20 as it was
initially:
It’s pretty obvious you go
left pick you’re through the little lakes.
With a bit of a revision it could be a very difficult route choice. Here’s a new version of it:
Here are the last few
controls.
I have never actually visited
the particular feature at control 21 but it’s nice forest around there and the
feature is unique in that it’s mapped in grey instead of in yellow even though
a lot of the rest of the yellow is mostly open rock so I wanted to take Yannick
to it. It’s also a great starting point
to a classic left / right route choice.
Because of the layout of the route it becomes very tempting to take the
right route choice heading out of control 21 because you’re closer to the line
on the first half of the leg.
I think the following route (dashed
purple) is best though because it takes you through a series of long fields
connected by white woods along a giant handrail that is nearly impossible to
screw up. The first bit of the leg takes
you over ground you’ve already travelled and the last bit is the same
regardless of you choose left or right.
Everyone has a different
course setting process and it can vary a lot depending on the terrain. In this case I already knew the terrain and
map quite well so I could sit down and plan this course in under an hour. As it was training for a single person I
wanted to set a good course but I wasn’t too worried about the details so that
helped as well. I didn’t pre-run any of
the route choice legs to find out which was the fastest which I probably would
have if it was for a major event but again, knowing the terrain, I could still
set good long legs based on the map along.
Sure it could have been optimized but so what? That wasn’t the purpose here.
Great post Jeff! Congrats.
ReplyDeleteI found this really interesting. I do remember the map quite well! Thank you.
