looks like a great run, if only you could flatten out the hills a bit
This is Briones Regional, near Martinez, CA. It's an amazing park, but really it's just too hilly for me. That is to say, there are some bits so hilly I was playing a mental game to see whether I could get up the slope without using my hands. Then at the top you see Mount Diablo...an impressive (and inspiring) sight. Then the real problem: the downs are so steep I am afraid to run them. Back when I was having such problems with bursitis in my left knee, it was definitely downhills that triggered it. So you are on the money: if only you could flatten outh the hills a bit!
Look Ma no hands!! Too steep for me.
