See my extensive writeup with course description and picture of the 2012 Everest Challenge as well as the 2011 Everest Challenge locations, maps, course notes which will be largely the same for 2012.
Race organizer Steven Barnes says:
2011 course again, except 11.2 miles up Waucoba Canyon, a little more than last year.
Registration and Free Pasta Feast and Pre-Race meeting will again be at the Tri-County Fairgrounds, but we will be in the (even larger) Chas. Brown hall.
We are offering some major goodies to Aid Station Volunteers! We could use a few more, as always. Replies to the Race Director, as usual.
Bishop Amateur Radio Club (BARC) will be out at the EC this year coordinating communications. Not an easy task, but these folks are the best. We will have more sweep vehicles, including some motorcycles.
