I have to generally echo this sentiment. I&#x27;m at about 1,900 miles for the year and will end up with about 2,500 by New Year&#x27;s (50 miles per week avg for the year). Most of the time my runs are enjoyable, except maybe the day after a hard workout. Sometimes I&#x27;ll hit a stride and end up going much faster than intended and the miles click by and I&#x27;m amazed at my pace and what I&#x27;ve done by the end.<p>The closest I come to &quot;runners high&quot; is usually on those days where it&#x27;s been a bit hot for long periods and then a cool front blows in. I&#x27;m practically giddy for the whole run and feel amazing. And I run races from 5k to 100 miles. I really, really enjoy racing, but I think it&#x27;s the competitive aspect of it and not from some runners high.
