Hmm, another poster I cannot see making a comment...
Ron, it did not go so well. To frame it. let me say that I can run 10 miles in about 1 hour, 20 minutes, road surface. Trail is always harder for me. This particular trail was a monster. If you make one loop, you gain (and lose) 11,000 feet (1/3 of Mt Everest). Not only do you have to move it along on the trail, you have to locate 11 way points where there are paperback books. You have to rip out the page corresponding to your race number (you get a new bib number on each lap). Between book one and two, I made a rookie mistake and lost my map & instructions and the page out of book one (which automatically DQd me). However, I manage to hang in there (for the experience) for another 10 miles. Then I found someone with a trail map and hiked out before dark. It took me 4.5 hours to go 10 miles. I put in about 16 miles that day.
The winner did do all 5 loops. Took him 57 hours. Three people finished the "fun run" (three loops) in about 36 hours.
