Yesterday I biked for about 13 hours (with breaks), maybe 200km (120 miles), twice as far as I’d planned. The weather was perfect, I had a tailwind, navigating was easy, and I was in a euphoric cycling state of mind. So when I reached my planned campground around 4, I kept going… and only when it started to get dark after 10 (solstice, moderately high latitude) did I think about stopping. I even found myself idly thinking about biking all night because I was in such a good mood– but fortunately common sense took over before I did something that crazy (I was out of food and water, only had a small light, canal ferries wouldn’t have been running). It’s a sickness, I tell you!
