Straight route = fastest?

They said: "Straight on routechoices is always better in Nackareservatet".
I tested if that statement was true in this video.
The result was… nice.

It can be dangerous to swim in a lake! Do it on your own risk!

Someone sold you a load of horsepuckey...must have been those guys at the bar the night before bragging about how they can run an O event along every purple line!!!

Yes those guys sure did fool me.. This is obviously to “run straight on” too literally I guess, but…if I only could swim faster and if it wasn’t a big hill in the way, then maybe it would be a great route choice!
