I used to be a long distance bicyclist.  I got my time in but nowhere near as much as you, but nobody there really experienced the high either.<p>What I actually experienced felt more like what we now call Flow, which is a pretty good experience by itself.  Programmers seek it out almost habitually, like an addiction.  I&#x27;ve also experienced the same thing once doing restorative Yoga (the teacher was experimenting at the end of a quarter, but I moved across town after), and maybe while doing meditation but it felt different.<p>I&#x27;m really curious if this is the high people mean, and those who rave about it just have a really hard time entering a flow state.  If that&#x27;s so then I pity them.<p>Thanksgiving before last this really gelled for me.  I had potatoes cooling on the stove and the dog was begging for a walk so I went out with him at like 10:15 am.  Runners.  Everywhere runners.  Then it hit me like a brick.  They were all out meditating, trying to mentally prepare for the onslaught of relatives and poorly behaved nieces and nephews that were about to descend on them.
