FLO - Moss Park

Nate and I had trained here at Moss Park a year ago while our skills were still rather weak.  To stack the odds, I had recently tweaked my lower back (herniated disc injury years ago) and Nate was out drinking til 2am.  We like a little challenge ;)

As usual, we drove to the park, thinking of new tactics or experiments we could try.  To start, Nate would take the navigating role for the first time on a simpler orange course.


Here's the map and our GPS route overlaid on the Orange course.  Worthy to note is how skewed the map is compared our GPS route (esp. at CP6)

CP1 always takes a little bit of time, as we always adjust and feel out the scale of the map.  As soon as we located the pier, we knew CP1 was in the vicinity.  It was well hidden deep in a thicket.  It took us a bit to figure out the faint trails, but in hindsight, a straight line bushwhack from the start was the best route, considering how open that area was.

Nate used an intersection to shoot a direct bearing to CP2.  The ideal point would be point B, the bend in the trail.  The CP was only about 75m from the path, a distance where you can easily see far enough to know when to shoot in.  Point A just added a little bit more bushwhack, and even though it didn't take much more time, on a longer race with vast distances, it adds up proportionally.

CP3, 4, 5
CP3 and 4 were pinpointed exactly.  Going to 5, Nate decided to use the border of Lake Hart as a handrail.  I let him do whatever :)  We found it after identifying the nearby parking lot from the distance.  The faster route would have been to get back on the trail, run north to the parking lot about halfway down, and then shoot a bearing in from there.

(after adjusting the route to fit that area of the map correctly...) Nate's decision was to bushwhack a straight line from the bottom part of the parking lot to CP6.  This was a great idea since the forest was really open and you could save lots of time by cutting down the distance.  Despite the initial measurement being slightly off, we found nearby attack points to gauge where CP6 was.  Measuring compass bearings can be pretty tough on the fly.  The longer the distance, the more time you should put in how accurate of a measurement it is.  Even as little as 2 degrees off of a 500m bearing translates into being off path about 18m at the end.

Anyways, we attacked CP6 many times, even with nearby teams doing the same thing.  It wasn't until another team tipped us off, that we got it.  On GPS playback, the blue circle (above) shows where we punched the CP, which correctly corresponded to the number on our punch card.  This one was severely out of place!

CP7, 8
CP7, and 8 was too easy for Nate.  He did the right thing by planning out the next control, while I punched the card.

Great job Nate!


Next up was me.  For CP1, I wanted to take the line indicated at the blue arrow (below).  Instead, the intersection (blue circled) crept up so fast that we just took the trail to the corner of the fence at CP1.

I recall measuring about 650m from the start of the causeway to the trail that ran down to CP2.  I counted probably 700m before we actually ran into it.  As we ran down, we counted another 300m or so before cutting in to find some distinct thickets.  Those were easy to see from the trail, however, there were a couple patches of them.  Luckily, we saw another set of people punching the right one.

From CP2 to 3, we shot a direct bearing.  The clue seemed like "series of ditches" or something like that.  Once we got there, luck again was on our side, as we found the control in the first ditch we ran into.  We saw another man literally carrying his team on his back--his baby--while orienteering.  Big props to him!

Heading out of CP3, I wanted to go straight south.  The orange areas on the map with vertical green lines "open land with undergrowth", which means there should be some form of slow running ability.  There was not, which is why you see us hook up north for a bit to see if there was a better opening to head south.  The blue arrow would have been the best route had I identified the high berm-like land feature better on the map.  There was an actual trail at the top of that berm, unmapped.

CP4, 5, 6
We made easy work out of CPs 4, 5, and 6 with direct bearings and pace counting.

Going out of CP6, however, I erroneously thought CP8 was next.  So I carved another bushwhack out for us thinking we had just punched CP7 (at CP6).  Uh oh...  As we committed, land features slowly did not add up to what I saw on map, but sometimes that happens.  I chalked it up to that.  We did find the trail we were looking for and the trail that headed east towards CP8.

As we kept pushing foward, we ran into a 4-way intersection that I was not expecting heading towards CP8.  Luckily I head counted paces from when we first hit trail.  Once I hit my numbers, I did not see any intersections in sight.  That's when I finally knew what happened.  I asked Nate if we had punched CP7, he confirmed no.  We immediately turned around, quickly found CP7, and headed out there with the same plan I had before.  Woo...that was 15minutes lost according to the GPS route.

This is the path I intended to use to take it out of CP7 and onto a trail (blue arrow below).

We made a kink in the line because the thorns there we so bad, Nate deemed it the worst bushwhack he had experienced.  He was leading the charge there with shorts, so I could understand (I had long pants which provided much more protection).  To add insult to injury, there was a stagnant low swamp we had to cross too.

So we poked out onto the trail at the exact spot I wanted, but cutting over looked too hairy.  We ran up some more and saw a break in the forest to cut through.

In hindsight, this is the route I would choose.  It minimizes the light green area (which could be the thorns), but allowed you not to cross swamp.  It also minimizes the distance under bushwhacking.  You never know though, until you go through it.  These are risks you take unless you know the park inside out.

CP8 was easy to navigate to.  We saw another team run there before we did, about 100m in front of us.  Their transition was piss poor slow though.  We steadily caught up, and without stopping, smoothly exited, while they were still waiting there measuring bearings and distances.  Both of us had two-man teams.  One man should punch, while the other figures a way out to the next.  It gives a seamless and quick transition.  It is little techniques like this that saves you a lot of time.  Imagine if you spent even just one minute at each control, measuring distances, for example.  On a course that has 13 control points, the team who can do this on the fly will finish a whopping 13minutes faster, which is significant.

CP9, 10, 11
At the intersection heading up to CP9, I couldn't identify the faintly mapped trail.  Fortunately, I had been counting paces and after 250m, I just had to cut into the forest look for this control.  It did not appear to be situated very far from the trail.  Bingo, easily found.  CP10 and 11 were easy to find while following the pond.

I wanted to attack CP12 purely with orienteering skills of "feeling the lay of the land out" by following the blue arrows (below).  After the trail bend, we ran up to the next intersection too fast that I only got to execute that plan half-way.  It worked and saved us some little distance.  This only works when the control is somewhat within visible distance from poking off the trail.  If that distance was, say 300m, I would definitely not risk taking that shortcut.  Accuracy is better on longer distances to a control, so running up to the closest known and mapped intersection is the way to go.

On the home stretch, I measured a bearing to CP13 and we cut across all types of roads towards it.

In the end, we completed two courses with a fatal error in each.  Better to make these errors during training than during races :)

On a side story, we had asked the volunteers to do a third course.  He said they wanted to wrap up, even after we promised a 15 minute white course completion time.  Blasphemy!  Canyoneros always do three or more courses!
