With 119 starters on Day 1 you would need 59½th place to make top half so you´re actually ahead ;)
Day 4 looks like a really nice area. I'd only run there once or twice - training on a very old map and not really got into the good bits. I remember it because I was running in my glasses (didn't have the contacts in for some reason) and a tree flicked my glasses off and I spent about 5 minutes crawling in the blueberries trying to find them. If I hadn't I might still be out there!
One of my clubmates lives on the map (one of the houses on the road bordering the SW edge of the map).
The steepest rockiest hillsides on the map look pretty typical of Ovik - unless you're running downhill it's just so slow (and technical). You have to be super careful. Even amongst the Scandinavians there would have been some pretty slow times I bet.
Not sure I should count non-starters and non-finishers, but in any case I slipped a couple of places on day 5 so the point is academic.
So far three of my best MTBO races this year have been sprints. Ironic given I'm notoriously bad at them (although Vic and Domsjo back up that assertion).
