Although I've mixed-in a few hills, the last week or so has been pretty flat; but today I returned to Cowles Mt. for some off road up and down. To make that worthwhile, I had to run up and over Cowles down toward Pyles Peak. That trail is nice. Cowles, on the other hand, is so rocky and up and down that I suspect too much is flat too much ;-)
The diversity was good, it beat me up, and the view of a "stormy" San Diego county was nice. Life advice (meaning this applies to everything . . . except wives): Diversify. Everything. Tomorrow's fare? Rolling. . .
