your trip looked amazing!
Not quite as epic as yours, but it was quite fun! I'm starting to do more and more vacations that don't revolve around running and I'm not sure how I feel about that...
Epic Iceland is epic! Also, especially when it's warmer, you can still run around Iceland.
I think visiting in the winter was quite special because of the lack of crowds, cheaper accommodation and wonderful frozen blue ice. I also think that we could have done more running than we did, though the center of the island still would have been offlimits. It would be fun to go back in the summer and run around more!
