Yojimbon, I wish I could have waited longer to get a few more awesome people like yourself to join in on the first leg. I had to move my start time up to tuesday, so now I’m in the hills off the san diego coast, about to head into the desert. Thanks for your enthusiasm, wanna join in phoenix?!
It sounds like he has gone maybe 150 miles in three and a half days. Can someone who knows the area verify? If that is correct he is going to need to pick up the pace if he is going to make it. I hope this means he is starting easy and building the pace otherwise it doesn't look too good.
