Yep, I'm beginning to understand that a successful ride means as much mental preparation as physical. I've done a fair bit of long days hiking and climbing, but I get really down/weepy when I'm tired (sleepy) and I have no tolerance at all for getting hungry. My dh knows enough to just hand me food when I start getting snarky

Daylight - we don't have midnight sun proper in Oslo, but it's light all day round. You could probably read outside almost all night. The sun slides down at a very gentle angle and just barely dips below the horizon, so you just have bright twilight for a few hours rather than any real darkness.

The downside is that I have to commute both ways in the dark for weeks in winter...
