12:30 Lunch (programme ends)

13:30 Mini-excursion to Holmenkollen Ski Jump (optional)

The famous Holmenkollen Ski Jump is right nearby the conference hotel (we pass it on the way back down to Oslo). For those who have time, we'll swing by the jump and the adjoining museum. You can even go up in the tower itself (and zip-line down again). https://www.visitoslo.com/en/product/?TLp=496475
