Hard to tell where the control is actually located since all tracks on the video above go first to the western edge then to the center and then a bit to the east.

Personally don’t know, did not go there.

One more nice mistake is on 1st control of 2nd leg. Turun Metsänkävijät has just made a great gap on Halden and loses it all + over 1 minute on 1st control. Priceless.

I suspect that the southern control 1 on leg 1 (as well as leg 2 & 3) is actually located 15-30 m further east from the center of the control circle, very close to where there is a boulder on the map:

When you study the GPS tracks above, you’ll notice that pretty much every runner stops and punches very close to the edge of the control circle.

A single GPS track is obviously not reliable, but when nearly all of them seem to punch in the same location, independently of the direction they hit the control from, then it is very likely that the map has a localized error there.

PS. The fact that I personally lost 8 minutes here on the 3rd leg, has of course nothing to do with my analysis. Jukola is always the best organized event of the year! :-)

Thank you for compiling this excellent coverage! It’s nice to have the ‘juicy bits’ picked out for my viewing. :)
