Nordie is that one a reject photo, there's no dust in it?

It's been treated to 2 layers of oil painting and the dust is behind me

Congratulations guys a great achievement. I always like how BusaJim always has such a huge smile on his face (while he's not face down ).

Awesome, just awesome guys ... I so want to get into this trail riding!

Found a rather cool side for creating maps from GPS data here. Ride elevation profile and route mapped on google maps attached.

This is Nordies GPX data (thanks Nordie). Nordie reconed the batteries went flat somewhere around Jacobs Ladder but I think it is closer to the pass over to Wakefield myself.

Bling to the first person that manages to name all the major high points (twelve points) along the elevation profile.

Just been going through and naming all the peaks on the elevation plot and have found that data is a little screwy after about the 900km mark (red 100ish m section before the peak at 1000kms). This fits in the with the GPSr batteries going flat.

Also did some calcs from the data and we climbed and lost a total of about 10.2kms. There is probably about another 300ms in it allowing for the Thorpe/Wakefield/Nelson leg.

Totally wicked guys

No Kanny that was nothing compared to what you did on the weekend, sure your ride was not as far, but much more demanding for you
You ride really well I was most impressed

Really nice to meet you too

Cheers Scott

Ride elevation profile

Although the distance scale is whacko; did it read in Nordie's values as miles and it convert them to kays at x1.6? The Howard Valley to Howard Valley section should appear as a mirror image (ink blot). It looks like almost the 2nd third is repeated as the last third??

Not sure what it has done with the millage but I think it is not too bad. It seems most of these types of sites calculate distance from the lat long points so miles vs kms shouldn't be an issue. I think the distances on the x axis is 2d distance though rather than the 3d distance as it tends to be a bit short. This means the slope of the roads (lines on the plot) would be correct (if it was plotted on a 1 to 1 scale) but the distance traveled is not the distance read from the x axis at the end of the route, rather you would have to measure the length of the line.

You need to ignore everything after the 1000m peak around the 900km mark. It seems that after that the file has corrupted (an repeated some how) or Nordie has gone back and re run some of the route and it has appended it to the file. The linear slope orange line between the 900ish and 1000ish kms indicates to me that the GPSr stopped recording somewhere around dovedale and it was turned back on again at another location - my guess is around St Arnaud and that Nordie was with Zukin when he redid the St Arnaud to Nelson section of the route on the Sunday Arvo. The lack of time stamp in the GPX file means I cant be sure though.

Nordie - how were you recording the track? If seems you have a heap of track points that were recoded manually at key locations (intersections etc). Would have been better (if your GPSr has the memory for it) to automatically record a point every 2 to 5 seconds. Much bigger file but get a much more accurate idea of the "shape" of the route. You understand the difference between GPS tracks and GPS routes i.e. routes are prepared on a computer uploaded and followed and tracks are points automatically recorded at a set interval or manually when out riding the route. Tracks obviously have much better data.

With a GPS it is better to set up the track as a distance measure instead of a time measure
I have mine set up to record every 100m, that way if I stop and the GPS is running I don't waste memory for the track record when I stop

I just didn't set it up to record DB

Good point about the distance. We use time for stuff we do at work cause we are more interested in speed (and time spent sitting still) than 3d profiles.

Shame on you for not recording the DB. This is exactly the data I need for my web site (it is coming just waiting for the Bro in law to come back to NZ to help). Got any other GPX track logs? Would be best if you break them us so they only cover one route (i.e. just the Mangatapu or just the Porika) each. I assume you can do this in the Mapsource software?

I did the pylon track as well on the way over the Porika
