I aspire to be a mountain runner, but I can't call myself one--yet. In a recent reading of Friedrich Nietzsche's Thus Spoke Zarathustra, I ran across this quote, apropos of mountain running:
In the mountains the shortest way is from peak to peak, but for that
route thou must have long legs.
If only. . . . But I guess a mountain runner would say the fun isn't only at the peaks, but on all the ridges and valleys in between.
