Our original plan was to start at the top of the Grimsel Pass and walk in to the Oberaarjoch hut, spending the next day "training" on a local peak, probably the Studerhorn.
On day 3 we would cross the Gemslicke, with a side excursion to the top of the Oberaarrothorn, and drop down to the Finsteraarhorn hut. The Finsteraarhorn was programmed for day 4.
Day 5 - up to the Fieschersattel and the Fiescherhorn, descending to the Mönchsjoch hut.
Days 6, 7, and 8 would be Mönch, Jungfrau, and Eiger, with the order and routes depending on conditions (ours and the mountains'). This gave us a day in hand, as we weren't due down in Grindelwald until day 9.
But it didn't quite work out like that.
