Yes, I did! It was pretty mental running along tow paths in complete darkness with only a head torch lighting the way. And having to choose and follow your own route added another level of wtf.
I started off strong as 4th women until halfway but that came back to bite me as my right hip and knee gave out and I had to pull out at 16k. Great format though, totally like an alleycat-on-foot, would definitely do it again.
See you there next October @Tenderloin?
