Today, even as I am writing this, runners are slogging around the course of the Capon Valley 50K in Yellow Springs, WV (you'll have to Google it, don't have the link handy).
I have run this race twice and I love it. I came very close to sending in my app to run it again this spring, but my weekends looked pretty jammed up, so I passed.
Now I am glad I did. It is an especially ugly and rainy day today. The stream crossings, indeed the whole course, must be a swollen, soggy mess. On a different day I would consider it to be a great adventure. Today I'm just glad I passed. Must be getting old, I guess.
