One of our participants, Jon André Fosstvedt, is in the making of 3 videos from the entire trail in Ecotrail Oslo. The first one is from the 80km-start to the 50km-start. This one is from 50km to 31km.
The last one from 31km to the finish line.
In the videos you should get an impression of how the trail is along the course. Some parts are technical, some are not.
