Looking at some GPS tracks from Jukola


I spent a few minutes studying GPS tracks from Jukola. It feels like following the race live...without the actual drama, of course, since you know how the race turns out.

Watching the tracks of the Halden SK and IFK Goteborg runners on the 2nd leg I was struck by how much time could be made up with some good trail routes. On the leg below, Halden and Goteborg were together at the trail junction at the south edge of this map clip. Mattias Karlsson from Halden sticks to the trail. Tobias Noborn from Goteborg head off trail, through the marsh. In just three minutes of running time (the tails on the track are 3 minutes long), Karlsson gets a minute lead.

Noborn might have learned something from that leg because on the next leg he stuck to the trail route. Noborn made up about 30 seconds with the route choice (and a bobble by Karlsson at the fourth control cost 30 seconds).

If I didn't have a job, I'd probably spend all day tomorrow looking at GPS tracks.
