On the north end of town, you can run / hike / cable car up into the "hills" (which still have more than 6,000 vertical feet up from Grindelwald) to get an even better view of the glaciers and huge mountains.
The weather did not cooperate quite as well in Grindelwald, but on our last day I went out in the morning for a run up the mountain. It was bluebird skies with some of the best views I have seen anywhere. My legs were still tired from the Sardona Ultra, but I was motivated to get as high as I could and above the treeline for some good views before I had to get back to our hotel to check out. I managed about 3,000 feet of climbing and descending in the 1:20 I had out there.
Sadly my camera lens on the iPhone was still super dirty from Sardona, but I figured the pictures were still worth sharing. There is a 51k and a 101k race in Grindelwald. Maybe someday I'll have to get back for that ...
