Cycling 600km in under 40 hours: How and Why.:

You’re connected to nature with no source of instant gratification at hand. In taking on a huge feat you’re submitting to something greater than yourself and the only way through it is to endure. Through enduring you learn more about yourself and in overcoming it, you develop a resilience and confidence that permeates into every aspect of your life.

@dbuntinx Does not sound like something I would do these days. (I used to cycle short 50km rides for the training). My uncle participated in “Den store styrkeprøven”, (500km, Trondheim-Oslo), but I don’t remember what time it took.
