Interestingly, my first exhilarating running experiences came about when I started trail running.<p>I wasn&#x27;t a heavy runner before, but I had trained for&#x2F;completed an Olympic triathlon, and run several miles every once in a while like most formerly-athletic people.<p>But the first time I ran on a trail in the woods I was like &quot;YEAH!&quot; and I still get no similar rush from street running though I do that 10+ miles a week these days.
