I'm signed up for my 2nd time doing the 50k. Last year I did it in a pair of Luna Origen huarache sandals which are about 13mm thick and use old tire treads. I think that was a bit of overkill when I really just needed something for the various gravel patches on the course. This year I'm hoping to do it in my homemade leather huaraches made from $10 of bullhide scrap and $5 of leather cord. There was one guy last year who did the 25k totally unshod. Looked to be older than me, maybe 55-60. Kind of curious if he's on here at all but didn't meet him and don't know his name! I just heard about him and saw a few pictures of him on the galleries at the web site. Are there any others planning on running this year?
